The information provided in the document describes the substantial equivalence of the "BD Vacutainer Citrate Blood Collection Tubes" to a predicate device, focusing on physical and chemical characteristics, rather than the performance of an AI or software device. As such, many of the requested categories for AI/software device evaluation (e.g., sample size of test set, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, training set sample size, how ground truth for training set was established) are not applicable to this submission.
However, I can extract information related to the device's performance testing and acceptance criteria as described for the medical device itself.

Clinical Performance Studies and Acceptance Criteria (as described):
The clinical studies aimed to demonstrate "Clinical Equivalence" and evaluated specific parameters. The acceptance criteria for these (e.g., non-inferiority margins) are not explicitly stated but are implied by the "demonstrated clinical equivalence" and "passed non-inferiority criterion" statements.
Study | Key Objective / Acceptance Criteria (Implied) | Reported Device Performance |
---|---|---|
Clinical Equivalence | Evaluate clinical equivalence of BD Citrate Tubes compared to a similar comparator citrate tube for PT, aPTT, INR, D-Dimer, Anti-Factor Xa. (Implied acceptance: demonstrating equivalence, likely within predefined statistical margins). | Clinical equivalence was demonstrated for all tube comparisons for representative selected plasma coagulation test parameters (PT, aPTT, INR, D-Dimer, Anti-Factor Xa). |
Within-Tube Stability (WTS) | Demonstrate within-tube stability for PT, aPTT, INR, D-Dimer, Anti-Factor Xa with BD Citrate Tubes. (Implied acceptance: stability within predefined limits over a specified time). | Demonstrated Within-Tube Stability (WTS) for representative selected plasma coagulation test parameters (PT, aPTT, INR, D-Dimer, Anti-Factor Xa). |
Shelf-Life Performance | Evaluate performance of BD Citrate Tubes at end-of-shelf-life (EOSL) compared to recently manufactured tubes for PT, aPTT, INR, D-Dimer, Anti-Factor Xa. (Implied acceptance: performance at EOSL is comparable to fresh tubes, supporting the proposed shelf-life). | The results support the proposed shelf-life for the selected plasma coagulation test parameters (PT, aPTT, INR, D-Dimer, Anti-Factor Xa). |
Repeatability/Reproducibility | Evaluate within-tube repeatability (duplicate testing), tube-to-tube reproducibility (two tubes/lot), and lot-to-lot reproducibility (three lots) for PT, aPTT, INR, D-Dimer, Anti-Factor Xa, compared to a similar comparator. (Implied acceptance: meeting non-inferiority criterion based on ratios appropriate to data structure). | The evaluation passed the non-inferiority criterion for all tube comparisons, based on the ratios appropriate to the data structure for the selected coagulation analytes when compared with a similar comparator citrate anticoagulant tube (PT, aPTT, INR, D-Dimer, Anti-Factor Xa). |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample sizes for the clinical test sets. It mentions "whole blood collected," but the number of subjects or samples is not specified.
Data Provenance: "Clinical testing was conducted on whole blood collected in the subject device, BD Citrate Tubes, and a similar comparator tube." This implies the data were collected from human subjects, likely in a clinical setting. The country of origin is not specified, and it's a prospective collection for these studies as they were performed to demonstrate equivalence.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not applicable. The device is a blood collection tube, not an AI diagnostic system requiring expert interpretation of primary data (like medical images). The "ground truth" for clinical performance likely refers to the analytical results obtained from the blood samples, which are objectively measured by laboratory instruments.
4. Adjudication Method for the Test Set
This information is not applicable for a device of this nature. Adjudication methods are typically relevant for subjective interpretations (e.g., by human readers in medical imaging studies).
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This is not applicable as the device is a blood collection tube, not an AI or software device that assists human readers.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
This is not applicable as the device is a blood collection tube, not an algorithm or AI system.
7. The Type of Ground Truth Used
For the clinical studies, the "ground truth" refers to the analytical measurements of coagulation parameters (Prothrombin Time [PT], Activated Partial Thromboplastin Time [aPTT], International Normalized Ratio [INR], D-Dimer, Anti-Factor Xa) obtained from the blood plasma after collection and processing. These are objective laboratory measurements, not expert consensus, pathology, or outcomes data in the typical sense for AI devices.
8. The Sample Size for the Training Set
This is not applicable as the device is not an AI/machine learning device that requires a training set.
9. How the Ground Truth for the Training Set Was Established

The provided text is a 510(k) summary for the BD MiniDraw Capillary Blood Collection System, a medical device for collecting blood samples. It discusses the device's intended use, comparison to a predicate device, and performance testing. However, it does not include information about AI/ML models, image analysis, or expert consensus/adjudication for establishing ground truth, which are typically found in the context of AI/ML-driven medical device submissions.
Therefore, many of the requested elements for describing the acceptance criteria and study proving device performance (especially those related to AI/ML, ground truth establishment by experts, and MRMC studies) cannot be extracted from this document.
The document focuses on the physical and chemical performance of a blood collection device, primarily comparing its ability to collect, transport, and preserve blood samples for Hemoglobin (HgB) and Hematocrit (HCT) analysis, and ensuring its stability, compatibility with existing lab equipment (Sysmex XN-Series™ analyzers), and user-friendliness.
Here's what can be extracted and what cannot:
1. A table of acceptance criteria and the reported device performance:
The document primarily lists non-clinical (bench) tests with a "Pass" outcome, indicating that the device met the established acceptance criteria for these physical and mechanical properties. For clinical performance, it states that "clinical equivalence" and "non-inferiority" criteria were met, but does not provide quantitative acceptance limits or exact reported values for these.

BD Vacutainer® EDTA Blood Collection Tubes are evacuated, sterile, single use, in vitro diagnostic medical devices. They are intended to be used by trained healthcare professionals for the collection, containment, preservation, and transport of human venous blood specimens used for in vitro diagnostic testing.
BD Vacutainer® K2EDTA and K3EDTA Blood Collection Tubes are used for testing in hematology including white blood cells (WBC), red blood cells (RBC), red blood cell distribution width (RDW), hemoglobin (HgB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular (MCH), mean corpuscular hemoglobin concentration (MCHC), platelets, and 5-part white blood cell (WBC) differential counts (neutrophils, lymphocytes, monocytes, eosinophils, basophils).
BD Vacutainer® K2EDTA Blood Collection Tubes and BD Vacutainer® K3EDTA Blood Collection Tubes are for collecting, transporting and centrifuging blood in a closed tube. The blood collection tube consists of closure assembly, a glass tube and EDTA additive.
The standard closure assembly is a basic rubber stopper. The tube is also available with the Vacutainer® Hemogard™ Closure Assembly which consists of a rubber stopper and protective plastic shield to reduce user exposure to blood. All stopper/closures are color coded to reflect additive type; the closures included in this submission are either pink or lavender to indicate the presence of the EDTA additive.
The provided text describes the regulatory submission for BD Vacutainer® K2EDTA and K3EDTA Blood Collection Tubes. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study of an AI/human reader device with acceptance criteria for performance metrics like sensitivity, specificity, or accuracy.
Therefore, many of the requested details about acceptance criteria, study design for AI/human reader performance, sample sizes for training/test sets in machine learning, expert adjudication, MRMC studies, standalone performance, and ground truth establishment in the context of AI are not applicable (N/A) to this document. This submission is for blood collection tubes, not a diagnostic algorithm.
However, I can extract information related to the performance testing of the blood collection tubes themselves.
Here's a breakdown of the relevant information from the document, with an emphasis on why certain requested fields are N/A:
1. A table of acceptance criteria and the reported device performance
Since this is for a medical device (blood collection tubes) and not an AI algorithm, the "acceptance criteria" are related to mechanical and physical performance, and clinical equivalence for blood parameters.
Test | Acceptance Criteria (Implied by "Pass" result and regulatory context) | Reported Device Performance |
---|---|---|
Draw Volume | Must meet defined specifications | Pass |
X-Value (likely relates to vacuum pressure or fill volume) | Must meet defined specifications | Pass |
Second Stopper Pullout | Must meet defined specifications for stopper integrity | Pass |
Stopper/Shield Separation | Must meet defined specifications for closure integrity | Pass |
Stopper Leakage | Must demonstrate no leakage | Pass |
Resistance to Breakage during Drop Testing | Must withstand specified drop tests without breakage | Pass |
Resistance to Breakage During Centrifugation | Must withstand specified centrifugal forces without breakage | Pass |
Ship Testing for Functional Performance of Packaging Materials | Must maintain integrity and function after simulated shipping | Pass |
Clinical Equivalence (Method Comparison) | Mean and 95% Confidence Limits of paired sample biases within Clinical Acceptance Limits (CALs) for key hematology parameters (WBC, RBC, RDW, Hgb, HCT, MCV, MCH, MCHC, Platelets, 5-part WBC differential) | Demonstrated for all parameters except Hgb, PLT, and WBC at low medically relevant points on two instruments (mean bias within CAL, but C.I. exceeded; deemed clinically acceptable due to insufficient low-point data) |
Precision (Lot to Lot Variability) | Non-inferiority for repeatability (within tube) and reproducibility (lot-to-lot and tube-to-tube) when compared to a comparator device for tested hematology parameters | Non-inferiority shown for all tube comparisons and hematology parameters on two instrument platforms. |
Within-Tube Type Stability | Analytes must demonstrate stability at specified storage conditions and time points (12- and 24-hours Room Temperature, 24 hours Refrigerated, 24 hours Room Temperature followed by 24 hours Refrigerated). | All analytes demonstrated stability. |
Shelf-Life | Product must maintain performance over proposed shelf life | 11 months for K2EDTA, 10 months for K3EDTA. |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size: The document does not specify the exact number of samples or subjects for the clinical studies. It mentions "low medically relevant points were insufficient to adequately power the analysis" for Hgb, PLT, and WBC in the method comparison, suggesting a limitation in that specific subgroup analysis.
- Data Provenance: Not explicitly stated (e.g., country of origin). The studies involved "testing performed internally and externally," and "clinical samples." There is no mention of prospective or retrospective design, but clinical equivalence and stability studies typically involve prospective collection or use of fresh samples to assess performance over time/conditions.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- N/A. This device does not rely on expert interpretation for "ground truth" in the way an AI algorithm for image analysis would. The "truth" for blood parameters is established by laboratory analyzers.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- N/A. Not relevant. This is not an image interpretation or diagnostic decision-making study that would require adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- N/A. Not an AI-assisted human reader study.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- N/A. Not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
- The "ground truth" for this device's performance would be the analytical results obtained from established, calibrated laboratory instruments (e.g., hematology analyzers) using the collected blood samples. Clinical equivalence was demonstrated against "legally marketed comparator tubes," implying that the comparator's performance on these instruments serves as the reference.
8. The sample size for the training set
- N/A. This is not an AI/machine learning device. There are no training sets.
9. How the ground truth for the training set was established
- N/A. Not an AI/machine learning device.

TransFix/EDTA Vacuum Blood Collection Tubes (TVTs) are intended for collection and storage of human whole blood specimens for immunophenotyping of white blood cells by flow cytometry. Recovery of lymphocyte subset markers of the HIV panel can be accomplished over a 14-day period following collection. TVTs are in-vitro diagnostic medical devices.
TransFix®/EDTA Vacuum Blood Collection Tubes (TVTs) are intended for collection and storage of human whole blood specimens for immunophenotyping of white blood cells (WBC, leukocytes) by flow cytometry up to 14-days following collection; the TVTs preserve the qualitative and quantitative leukocyte subset characteristics. Flow cytometry is used to identify subsets of leukocytes that can be distinguished on the basis of cell surface antigens using fluorescent antibodies.
The TransFix®/EDTA Vacuum Blood Collection Tubes (TVTs) consist of purple-capped polyethylene terephthalate blood collection tubes containing the paraformaldehyde based preservative, TransFix, and K2EDTA at the correct volume to simultaneously stabilize and anticoagulate human whole blood at the time of collection. TVTs hold 3mL (final draw volume) with a tube dimension of 13 x 75mm. TVTs are sterilized by gamma radiation. Further, the vacuum contained within the TVT ensures that the TransFix/EDTA reagent is administered at the correct ratio of 1 part TransFix/EDTA to 5 parts whole blood.
The provided text describes the performance of a medical device, the TransFix®/EDTA Vacuum Blood Collection Tubes (TVTs), and presents data to support its substantial equivalence to a predicate device. However, it does not explicitly state acceptance criteria or a specific study proving the device meets those criteria in the typical sense of a diagnostic test performance study (e.g., sensitivity, specificity thresholds).
Instead, the documentation focuses on reproducibility (precision) and equivalence (method comparison) to a reference method and a predicate device. The "acceptance criteria" are implied by statements regarding "sufficiently precise" and the comparison tables to accepted methods.
Here's an attempt to extract and present the information given available:
Acceptance Criteria and Device Performance
Implied Acceptance Criteria:
Based on the text, the device aims to demonstrate:
- Reproducibility (Precision): Individual and total %CVs (Coefficient of Variation) are "less than 10% and 15%, respectively" for absolute cell counts of specific lymphocyte biomarkers (CD3, CD8, CD45, CD16/CD56, CD19). This is the key performance metric measured.
- Equivalence: The absolute counts of lymphocyte subsets (CD3, CD4, CD8, CD16/56, CD19, and CD45) in TVT tubes should be comparable to those obtained from the predicate device (Cyto-Chex® BCT) and a gold standard (BD EDTA tubes) over a 14-day storage period. This is assessed via Passing-Bablok regression with slopes and intercepts within an acceptable range, and high R-values indicating strong correlation. The exact thresholds for acceptable slope/intercept/R are not explicitly stated as "acceptance criteria" but are implied by the presentation of the data for a substantial equivalence claim.
- Non-Interference: The performance of the TVTs should not be significantly affected by common interfering substances (bilirubin, hemoglobin, triglycerides).
Reported Device Performance:
Reproducibility Studies:
The tables in the document (Tables 1-12) present %CVs for various biomarkers under different conditions (Between-Day, Between-Lot, Between-Tube, Between-Replicate, Between-Site) and indicate that the TVT lots were "sufficiently precise" against the implied criteria of individual and total %CVs being less than 10% and 15% respectively. For example, in Table 1 (CD3+ biomarker), all total %CVs are well below 15% (ranging from 4.7% to 6.2%). Similar observations are made for all other biomarkers across both reproducibility studies.
Equivalence Study (Method Comparisons):
Tables 12 and 14 (for HIV positive subjects and healthy subjects, respectively) show Passing-Bablok regression results comparing TVTs and BCTs against BD EDTA tubes.
- Slopes: Most slopes for TVT (and BCT) are close to 1.0, indicating good agreement with the BD EDTA control. For HIV-positive subjects, TVT slopes are generally between 0.95 and 1.12. For healthy subjects, TVT slopes are generally between 0.90 and 1.10.
- Intercepts: Intercepts are generally small for both TVT and BCT, indicating minimal systematic bias.
- R-values: All R-values are high (0.95-1.00), demonstrating a strong correlation between the TVTs (and BCTs) and the BD EDTA control for the listed markers.
- The text explicitly states: "The TVT tubes were found to be safe and effective for the intended use."
Interference Study:
The study observed "no significant effects from the potential interferents listed" when comparing results from aliquots with added interfering substances to a control aliquot. This indicates the device meets the non-interference aspect of its performance.
Study Details:
-
A table of acceptance criteria and the reported device performance:
(Combined above based on implicit criteria in the text). -
Sample size used for the test set and the data provenance:
-
Reproducibility Study 1 (Intra-lab variability):
- Sample Size: 5 healthy subjects. For each subject, blood was collected into six TVTs (two tubes from each of three lots). Testing was performed at three time points (0, 12, 15 days post venipuncture) with triplicate determinations on each of the duplicate TVTs from each of the three lots. (N=54 mentioned for each subject for each biomarker calculation, indicating total determinations).
- Data Provenance: Not explicitly stated, but the context of submitting to FDA suggests a regulated environment. Likely prospective, as it's a specific study design.
-
Reproducibility Study 2 (Inter-site variability):
- Sample Size: 5 healthy subjects. Blood collected into six TVTs (from the same lot) from each subject. Tested at three clinical flow cytometry laboratories. Testing performed with triplicate determinations on each of the duplicate TVTs. (N=18 mentioned for each donor for each biomarker calculation).
- Data Provenance: UK (from "three clinical flow cytometry laboratories in the UK"). Likely prospective.
-
Equivalence Study (Method Comparison):
- Sample Size: 30 HIV positive donors and 12 normal donors.
- Data Provenance: Not explicitly stated, but the context implies data collected for this registration. Likely prospective.
-
Interference Study:
- Sample Size: 5 healthy subjects and 5 HIV positive subjects.
- Data Provenance: Not explicitly stated. Likely prospective.
-
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This document describes a device for sample collection and preservation rather than a diagnostic algorithm that interprets images or patient data. Therefore, the concept of "experts establishing ground truth" in the way it applies to AI/radiology devices is not directly applicable here. The ground truth for lymphocyte counts is established by flow cytometry using a reference method (BD EDTA tubes) and accepted laboratory procedures. The "experts" would be the trained laboratory personnel performing the flow cytometry and data analysis. Their specific qualifications are not detailed in this summary.
-
Adjudication method for the test set:
- Not applicable in this context. This is a quantative measurement of cell counts, not an interpretation requiring adjudication.
-
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No, an MRMC study was not done. This device is a blood collection tube, not an AI diagnostic algorithm for human interpretation.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an algorithm.
-
The type of ground truth used:
- For the equivalence study, the ground truth was established by immediate (Day 0, within 6 hours) analysis of blood samples collected in BD EDTA tubes, considered the reference condition for immunophenotyping. This represents a "reference method" ground truth.
-
The sample size for the training set:
- Not applicable as this is a physical device (blood collection tube) and not an algorithm requiring a training set in the machine learning sense. The "training" of the tubes is inherent in their manufacturing process and formulation.
-
How the ground truth for the training set was established:
- Not applicable (as above).

Cyto-Chex® BCT™ is intended for collection and storage of blood specimens for immunophenotyping of WBC by flowcytometry. Recovery of lymphocyte subset cell markers of the HIV panel can be accomplished over a 14-day period following collection.
Cyto-Chex BCT consists of a standard 13 x 75mm glass blood collection tube containing 75.8ul of sterile KJEDTA anti-coagulant and WBC preservative. It is manufactured with a vacuum to draw 5ml of blood by venipuncture.
Here's a breakdown of the acceptance criteria and the study that demonstrates the device meets these criteria, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance:
Acceptance Criteria | Reported Device Performance |
---|---|
Clinically important HIV markers (CD3, CD4, and CD8) are stable in samples collected in Cyto-Chex BCT. | Confirmed. CD3, CD4, and CD8 showed agreement with reference values (fresh K2EDTA samples within 6 hours). |
Agreement of values with fresh samples: trendline slope better than 0.90 (preferably 0.95), R^2 values of 0.85 or better. | Values for CD3, CD4, and CD8 from Cyto-Chex BCT stabilized samples confirmed through calculated correlation statistics meeting acceptance criteria. (Specific slope and R^2 values are not explicitly given, but the text states they meet the criteria). |
Recovery of CD3, CD4 and CD8 markers well within the acceptance criteria for absolute cell count. | Confirmed in both HIV-positive and healthy donors. |
Preservation of HIV markers for a 14-day period following collection. | Confirmed for CD3, CD4, and CD8 in both HIV-positive and healthy donors. |
CD19 stability. | Showed "some deterioration at 14 days" but the report suggests "additional patient sampling would probably improve the results." (This indicates it may not have fully met the criteria or was a borderline finding that Streck believes could be improved with more data, but was deemed acceptable for the intended use of CD3/CD4/CD8). |
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: The text states "multiple healthy donors" and "samples from HIV positive patients." Specific numerical sample sizes for either group are not provided.
- Data Provenance: Not explicitly stated, but it implies a prospective clinical study where fresh blood samples were collected and then split into different tubes and analyzed over time. The mention of "resource-poor countries" in the conclusion suggests a global relevance, but doesn't specifically state the origin of the study participants. The study tested both healthy and HIV-positive individuals.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
- Number of Experts: Not mentioned.
- Qualifications of Experts: Not mentioned. The ground truth was established by laboratory analysis using flow cytometry, a standardized method. The expertise would lie in the technicians performing and interpreting these tests, but their specific qualifications are not detailed.
4. Adjudication Method for the Test Set:
- Adjudication Method: Not applicable. This device is a blood collection tube for sample preservation, not an AI diagnostic tool requiring expert adjudication of image interpretations or similar subjective assessments. The "ground truth" was derived from direct laboratory measurements (flow cytometry results of fresh samples).
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:
- MRMC Study: No. This is not an imaging or diagnostic device that involves human interpretation of results. Therefore, an MRMC study is not relevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:
- Standalone Performance: No. This is a medical device (blood collection tube) that is designed to preserve biological samples. Its performance is assessed by how well it maintains the integrity of the sample, not as an algorithm performing a task autonomously.
7. The Type of Ground Truth Used:
- Type of Ground Truth: The ground truth was established by direct laboratory measurement from fresh samples (specifically, flow cytometric data for lymphocyte subset cell-surface markers from K2EDTA blood collection tubes analyzed within 6 hours of draw). This serves as the "reference value" against which the Cyto-Chex BCT preserved samples were compared.
8. The Sample Size for the Training Set:
- Sample Size for Training Set: Not applicable. This is not an AI/ML device that requires training. The device's performance is based on its physical properties and chemical composition to preserve blood samples.
9. How the Ground Truth for the Training Set Was Established:
- Ground Truth for Training Set: Not applicable, as there is no training set for this type of device.

The VACUTAINER® Brand PLUS (plastic) Tube with EDTA is an evacuated blood collection tube which provide a means of collecting, transporting, separating and processing blood in a plastic tube. When the tube is used together with VACUTAINER® Brand Needles and Holders, it is a closed system for the collection of venous blood with the same indications as described herein.
Blood collected in a tube containing EDTA Anticoagulant is primarily used for clinical laboratory testing-hematology study using whole blood but may be used for other studies including such studies as testing for lead and FEP analyses, requiring whole blood as determined by the laboratory.
The VACUTAINER® Brand PLUS Tube with EDTA is an evacuated plastic tube for collecting, transmitting and processing blood in a closed plastic tube. The blood collection tube consists of closure assembly, a plastic tube and EDTA coating (dipotassium, K2). The plastic tube is manufactured from PET (Polyethylene terepthalate Plastic and enhances user safety and disposal because of the reduced risk of tube breakage and incineration as a method of disposal. The standard closure assembly is a basic rubber stopper. The tube is also available with VACUTAINER Systems Hemogard™ Closure assembly which is designed to reduce user exposure to blood. The EDTA anticoagulant tube coating is spray coated in a dipotassium (K2) form. The EDTA prevents specimen coagulation.
The provided text describes a 510(k) premarket notification for the VACUTAINER® Brand PLUS Tube with EDTA Anticoagulant. Here's an analysis of the acceptance criteria and study information:
1. Table of Acceptance Criteria and Reported Device Performance:
Acceptance Criteria / Performance Metric | Reported Device Performance |
---|---|
Equivalence for FEP (Free Erythrocyte Protoporphyrin) Analysis (compared to VACUTAINER® Brand Glass Tube with EDTA) | Demonstrated analytically and statistically equivalent results and sample stability at initial time and extended tube storage. |
Equivalence for Blood Lead Analysis (compared to VACUTAINER® Brand Glass Tube with EDTA) | Demonstrated analytically and statistically equivalent results and sample stability at initial time and extended tube storage. |
Lead Level in Tubes (Maximum limit is 2.5 ug/L (ppb) as per draft product labeling for the Becton Dickinson VACUTAINER Systems Plus Plastic Tube with EDTA) | All tubes from three different lots tested had lead levels below 2 ug/L. |
Reduced Risk of Tube Breakage | Achieved, as described in prior 510(k) K901449/A. |
Enhanced Disposal (Incineration as method) | Achieved, as described in prior 510(k) K901449/A. |
2. Sample Size Used for the Test Set and Data Provenance:
- For FEP and Blood Lead Analysis: The specific sample size for the clinical evaluation comparing the Plus Tube to the Glass Tube is not explicitly stated.
- For Tube Lead Levels: "Twenty tubes from each of the three lots" were tested, totaling 60 tubes (20 tubes/lot * 3 lots).
- Data Provenance: The document does not specify the country of origin for the clinical evaluation data. It is a prospective comparison study for FEP and Blood Lead, and an analytical/bench study for tube lead levels.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
- The document describes analytical and statistical equivalence based on laboratory measurements (FEP, Blood Lead, Atomic Absorption for lead). It does not mention the use of human experts to establish "ground truth" in the typical sense of expert consensus for diagnostic interpretation.
- The "ground truth" for FEP and Blood Lead would be the quantitative measurements themselves, and for lead levels, it would be the results from Atomic Absorption.
4. Adjudication Method for the Test Set:
- Adjudication methods (e.g., 2+1, 3+1) are typically relevant for studies involving human interpretation of diagnostic images or clinical assessments where there might be inter-reader variability.
- Given the nature of the tests (quantitative analyte measurements and material analysis), no adjudication method was mentioned or appears to be applicable in this context. The determination of equivalence and lead levels relies on direct analytical measurements.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done:
- No, an MRMC comparative effectiveness study was not done. The study design involved comparing a new medical device (plastic tube) to an existing device (glass tube) for its ability to preserve sample integrity for specific laboratory tests (FEP and Blood Lead) and for its material properties (lead levels in the tube). This is not equivalent to an MRMC study which typically assesses the impact of AI on human reader performance in diagnostic tasks.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done:
- This device is a blood collection tube, not an AI algorithm. Therefore, the concept of "standalone performance" for an algorithm is not applicable. The device's performance is driven by its material properties and manufacturing, assessed through analytical and clinical laboratory testing.
7. The Type of Ground Truth Used:
- Quantitative Analytical Measurements:
- For FEP and Blood Lead analyses: The "ground truth" was established by quantitative measurements of FEP and blood lead levels from blood samples collected in both the test (plastic) and predicate (glass) tubes. The comparison was based on the numerical results and their statistical equivalence.
- For tube lead levels: The "ground truth" was established by Atomic Absorption (AA) measurements of lead levels within the tubes.
8. The Sample Size for the Training Set:
- This device is a physical medical device (blood collection tube), not an AI model that requires a "training set." Therefore, the concept of a training set does not apply to this submission.
9. How the Ground Truth for the Training Set was Established:
- As concluded in point 8, there is no training set for this device.

The Greiner Vacuette® blood collection tube with sodium citrate is an evacuated blood collection device containing sodium citrate anticoagulant additive. The tube material for the Greiner product is clear plastic.
This document is a 510(k) summary for a blood collection tube, not a medical device involving AI or complex algorithms. Therefore, much of the requested information (e.g., AI performance, expert consensus, training sets, MRMC studies) is not applicable.
Here's the relevant information based on the provided text:
I. Acceptance Criteria and Study Details for Greiner Vacuette® Blood Collection Tube with Sodium Citrate
This submission describes a direct comparison study to establish substantial equivalence for a new medical device (blood collection tube) with an existing predicate device. The acceptance criteria and performance are based on the correlation of results from these two devices for specific laboratory tests.
1. Table of Acceptance Criteria and Reported Device Performance
Parameter Tested | Acceptance Criteria (Implied) | Reported Device Performance |
---|---|---|
Coagulation Analyses (2 parameters) | "Good correlation" of test results between the Greiner Vacuette® tube and the predicate Becton Dickinson Vacutainer® tube. | "Good correlation was observed." |
Note: The document does not explicitly state numerical acceptance criteria (e.g., correlation coefficient thresholds). Instead, it uses the qualitative term "good correlation."
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated. The study involved "paired samples."
- Data Provenance: Not specified (e.g., country of origin, retrospective or prospective). However, given the nature of a 510(k) submission for a physical device, it's highly likely to be prospective clinical laboratory testing conducted in a controlled environment.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
- Not Applicable: For a blood collection tube, "ground truth" is established by the analytical results of standardized laboratory tests. There are no human experts interpreting images or making diagnoses in this context to establish a conventional "ground truth." The "ground truth" is effectively the result obtained from the predicate device which is considered the standard.
4. Adjudication Method for the Test Set
- Not Applicable: Adjudication methods are typically used for subjective diagnostic tasks (e.g., image interpretation). This study involves objective laboratory measurements. The comparison is direct, not interpretive.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
- No: An MRMC comparative effectiveness study is not applicable as this device is a blood collection tube, not an AI-powered diagnostic tool requiring human interpretation.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Not Applicable: This is a physical blood collection device, not an algorithm, so "standalone performance" in the AI sense is not relevant. The performance is the analytical result generated by the laboratory instrument after blood collection in the tube.
7. The Type of Ground Truth Used
- Comparator Device Results: The "ground truth" or reference standard for comparison was the results obtained from the Becton Dickinson Vacutainer® sodium citrate tube (predicate device). The equivalency was evaluated by comparing test results from the new device against the established predicate.
8. The Sample Size for the Training Set
- Not Applicable: This is a physical medical device, not an AI model. Therefore, there is no "training set."
9. How the Ground Truth for the Training Set Was Established
- Not Applicable: As there is no training set for this type of device, this question is irrelevant.
