The analyzer offers 2 models: one with Bluetooth function for printing the test results and transferring data to a PC via Bluetooth technology and the other without it. The analyzer without the Bluetooth unit can still print the test results and transfer the data to a PC using a cable.
The system includes Lipid Profile Test Strip which is based on a reflectance photometry, and Glucose Test Strip which is based on glucose oxidase biosensor.
There are also lipid check strips and glucose check the internal malfunction (or problem) of the analyzer prior to testing.
The code chip is for the analyzer to read the lot-specific characteristics of the test strips currently in use. The SD Ezi Tube+ is used to apply blood sample for lipid profile testing.
Here's a breakdown of the acceptance criteria and the study information for the SD LipidoCare systems, based on the provided document:
The document combines information for four devices: SD LipidoCare Home System, SD LipidoCare Professional System, SD LipidoCare BT Home System, and SD LipidoCare BT Professional System. All four systems are intended for the quantitative measurement of glucose, total cholesterol (TC), triglycerides (TG), and HDL cholesterol (HDL) in capillary whole blood. The "BT" versions add Bluetooth functionality.
It's important to note that the provided document is a 510(k) summary, which focuses on demonstrating substantial equivalence to predicate devices, rather than a detailed clinical study report with explicit acceptance criteria for each performance metric. Therefore, some information, particularly around specific acceptance criteria values and the detailed methodology of how "ground truth" was established, is inferred or generalized from the context of substantial equivalence testing for IVD devices.
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state quantitative acceptance criteria in a table format for the subject devices (SD LipidoCare systems). Instead, it relies on demonstrating substantial equivalence to predicate devices. However, it does list the test ranges for both the predicate and new devices, which can be seen as the operational range where performance is expected to be acceptable. Performance is generally presented as "substantially equivalent" rather than with specific quantifiable metrics against a pre-defined criterion table.
Inferred Performance and Comparison:
Attribute | Predicate: PTS PANELS Lipid Panel Test Strips | New Devices: SD LipidoCare (BT) Professional/Home (Lipid) | Predicate: SmartLink™ GOLD Blood Glucose Monitoring System | New Devices: SD LipidoCare (BT) Professional/Home (Glucose) |
---|---|---|---|---|
Test Range (Lipid) | ||||
TC | 100-400 mg/dL (2.59-10.36 mmol/L) | 100-450 mg/dL (2.59-11.6 mmol/L) | N/A | N/A |
TG | 50-500 mg/dL (0.57-5.65 mmol/L) | 45-650 mg/dL (0.51-7.43 mmol/L) | N/A | N/A |
HDL | 15-100 mg/dL (0.57-2.59 mmol/L) | 25-95 mg/dL (0.65-2.46 mmol/L) | N/A | N/A |

Acceptance Criteria Implication: For many IVD devices, acceptance criteria often relate to accuracy (bias, precision), linearity, interference, and user performance. The document states that "We performed various clinical and bench tests and the test results supported that despite these differences the [subject device is] substantially equivalent to the predicate devices." This implies that the performance of the new devices, within their specified (and sometimes wider) ranges, met the accepted performance characteristics typically associated with the predicate devices, thereby not raising questions of safety and effectiveness.
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the sample size used for the "clinical and bench tests" that demonstrated substantial equivalence.
Data Provenance: The manufacturer is SD Biosensor, Inc. from the Republic of Korea. The document does not explicitly state whether the data was retrospective or prospective, but clinical and bench testing for 510(k) submissions are typically prospective studies designed to evaluate the new device's performance.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
The document does not specify the number or qualifications of experts used to establish ground truth. For in vitro diagnostic (IVD) devices measuring biomarkers, ground truth is typically established using established laboratory reference methods performed by qualified laboratory personnel, rather than expert consensus on image interpretation.
4. Adjudication Method for the Test Set
The document does not mention an adjudication method. For quantitative measurements by IVD devices, adjudication (like 2+1 or 3+1 for imaging studies) is generally not applicable in the same way. The comparison is usually made directly against a reference method.
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
No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic imaging devices where AI assists human readers. The SD LipidoCare systems are in vitro diagnostic devices for quantitative measurement of blood analytes.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
The device itself is a standalone measurement system (analyzer and test strips). Its performance is inherently "standalone" in the sense that it provides a quantitative result without direct human interpretation of complex visual data or complex human-AI interaction. The "clinical and bench tests" would have evaluated this standalone performance.
7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)
For IVD devices measuring analytes like glucose, total cholesterol, triglycerides, and HDL cholesterol, the ground truth is typically established using reference laboratory methods (e.g., enzymatic colorimetric methods on a chemistry analyzer) operated by trained laboratory professionals. These methods are considered the gold standard for accurate quantitative measurements for these specific analytes in blood. The document implies this approach through its discussion of "Substantial Equivalence," which generally means the device's results correlate sufficiently with established laboratory methods.
8. The Sample Size for the Training Set
The document does not specify the sample size for a "training set." These devices typically do not involve AI algorithms that require explicit "training sets" in the conventional machine learning sense. Their performance is based on the chemical and enzymatic reactions within the test strips and the photometric/biosensor reading technology, which are validated through analytical and clinical studies.
9. How the Ground Truth for the Training Set Was Established
As noted above, a "training set" in the machine learning sense is not applicable here. The device's underlying principles (e.g., enzymatic reactions for glucose, photometric reading for lipids) are based on established scientific methods. Any calibration or internal adjustments made during manufacturing (which would be analogous to "training" in a very broad sense) would be done against reference standards, with the "ground truth" being the known concentrations of those reference standards.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document explicitly states: "Clinical sensitivity and clinical specificity testing are not applicable." This implies that no clinical performance study involving a patient test set was conducted for this 510(k) submission, as the focus was on demonstrating substantial equivalence based on non-clinical tests (design control, risk analysis, verification & validation activities) due to the nature of the modifications (primarily adding Bluetooth connectivity). Therefore, sample size for a clinical test set and its provenance are not provided.
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)
Not applicable, as no clinical test set was used for this submission.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, as no clinical test set was used for this submission.
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
Not applicable. This device is a blood glucose monitoring system, not an AI-assisted diagnostic imaging device that would typically involve human readers and MRMC studies.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is a standalone blood glucose meter. Its performance is evaluated intrinsically, and the "study" demonstrating its performance relies on the device itself against a reference method (not detailed here, but expected for glucose meters). The document indicates "design control, risk analysis and verification & validation activities" were performed, which would include testing the device's accuracy and precision, but the specific details of these tests (e.g., sample size, reference method) are not included in this summary.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For a blood glucose monitoring system, the "ground truth" would typically be established by a laboratory-grade reference method for glucose measurement (e.g., YSI glucose analyzer), which is considered the gold standard. However, the document does not explicitly state the specific reference method used for the verification and validation activities.
8. The sample size for the training set
Not applicable in the context of an AI/algorithm training set. For a traditional medical device like a glucose meter, "training" might refer to calibration data, but the document does not provide details on the sample size for such data.
9. How the ground truth for the training set was established
Not applicable in the context of an AI/algorithm training set. For a glucose meter, the ground truth for calibration (if considered "training") would be established by measuring known glucose concentrations against a reference method.

2. Sample Size Used for the Test Set and the Data Provenance
The document explicitly states that "the non-clinical studies and clinical-studies provided in this submission demonstrated that the differences do not raise and effectiveness." The list of tests on page 9 includes "System Accuracy," "Precision," "Linearity," "Sample Volume," "Hematocrit," "Matrix comparison," and "Interference Substances," which typically involve clinical or non-clinical data.
- Sample Size: The document does not specify the sample size used for any of the clinical or non-clinical tests (e.g., system accuracy, precision, linearity).
- Data Provenance: The document does not specify the country of origin for the data or whether the study was retrospective or prospective. It generally refers to "non-clinical studies and clinical-studies."
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
The document is for a Blood Glucose Monitoring System, which measures a quantitative value (glucose concentration). For such devices, the "ground truth" (or reference method) is typically established using a highly accurate laboratory reference instrument, not by human expert consensus or radiologists.
- Therefore, the concept of "number of experts" and "qualifications of those experts" for establishing ground truth, as typically applied to image-based diagnostic systems, does not directly apply here. The ground truth for glucose measurements would be derived from a laboratory reference method.
4. Adjudication Method for the Test Set
As explained above, for a quantitative measurement device like a blood glucose meter, the ground truth is established by a reference laboratory method rather than by human interpretation requiring adjudication.
- Thus, adjudication methods (e.g., 2+1, 3+1) are not relevant to the type of ground truth used for this device.
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
The SD GlucoNFC Blood Glucose Monitoring System is a device designed for direct measurement of blood glucose, not an AI-powered image analysis system that assists human readers in diagnosis.
- Therefore, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study is not applicable to this device. There is no mention of AI assistance or human readers improving diagnostic accuracy with the device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
This device is a standalone glucose measurement system. The blood glucose meter provides a numerical result directly to the user or healthcare professional. There isn't an "algorithm only" component separate from the meter's function, as the meter itself performs the measurement.
- The performance metrics like "System Accuracy," "Precision," and "Linearity" inherently represent the standalone performance of the device (the meter and test strip system).
7. The Type of Ground Truth Used
For a blood glucose monitoring system, the ground truth is typically established against a laboratory reference method that is highly accurate and precise, often a hexokinase or glucose oxidase method run on a clinical chemistry analyzer.
- The document implies this by stating "System Accuracy" and "Matrix comparison" tests were performed, which compare the device's readings to a known, precise reference. It does not explicitly name the reference method but it's understood in the context of these devices.
- It is not expert consensus, pathology, or outcomes data.
8. The Sample Size for the Training Set
The document describes premarket notification (510(k)) to demonstrate substantial equivalence, focusing on testing the final device. It does not mention a "training set" in the context of machine learning or AI.
- This device is a traditional electrochemical biosensor, not an AI/ML-based system requiring a distinct training dataset.
9. How the Ground Truth for the Training Set Was Established
As there is no mention of an AI/ML component or a "training set," this question does not apply to the information provided.

Here's a breakdown of the acceptance criteria and study information for the SD A1cCare System, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document explicitly states that "All testing met acceptance criteria," but it does not provide a table with specific numerical acceptance criteria alongside the reported device performance for each test. Instead, it lists the types of tests conducted.
To provide a tabular format, I will extract the types of tests mentioned under "Functional and Safety Testing" and indicate that the results met unstated acceptance criteria.
Acceptance Criteria Category | Reported Device Performance |
---|---|
NGSP certification | Met acceptance criteria |
Accuracy method comparison | Met acceptance criteria |
Linearity | Met acceptance criteria |
Precision | Met acceptance criteria |
Comparison of Spoit Type test kit performance | Met acceptance criteria |
Hematocrit range | Met acceptance criteria |
Interferences | Met acceptance criteria |
Hemoglobin variants | Met acceptance criteria |
Total hemoglobin | Met acceptance criteria |
Altitude | Met acceptance criteria |
Testing time | Met acceptance criteria |
Operating temperature range | Met acceptance criteria |
Optimal sample and mixture volume | Met acceptance criteria |
Anticoagulants | Met acceptance criteria |
Sample collection and preparation | Met acceptance criteria |
Stability of blood samples | Met acceptance criteria |
Vibration | Met acceptance criteria |
Temperature and humidity | Met acceptance criteria |
EMC and electrical safety testing | Met acceptance criteria |
Shelf-life testing | Met acceptance criteria |
Software verification and validation | Met acceptance criteria |
2. Sample Sizes Used for the Test Set and Data Provenance
The document mentions "a user study clinical evaluation was conducted comparing home user results against a reference method." However, it does not specify the sample size for this test set nor the specific country of origin for the data. It implies the data is prospective, gathered from the user study.
For other functional and safety tests, no specific sample sizes are provided.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
The document does not provide information on the number or qualifications of experts used to establish ground truth. It states "comparing home user results against a reference method," but the nature of this reference method and the involvement of experts in its establishment or application are not detailed.
4. Adjudication Method for the Test Set
The document does not specify an adjudication method. It only mentions a comparison against a "reference method."
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not explicitly mentioned or described. The device is an immunoassay system designed for quantitative measurement, not an imaging or diagnostic aid typically assessed via MRMC studies. The "user study clinical evaluation" compared home user results to a reference method, which is different from an MRMC study assessing human reader improvement with AI assistance.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance)
Yes, the studies described are indicative of standalone performance of the device. The "SD A1cCare System" is an automated reflectometry immunoassay system. The bench testing and clinical evaluation would assess the performance of this system (analyzer and test kit) in isolation, measuring its accuracy, precision, linearity, etc., without an explicit human-in-the-loop component influencing the measurement itself. The "user study clinical evaluation" did involve home users, but their role was in operating the device, not in interpreting results in conjunction with an AI algorithm.
7. Type of Ground Truth Used
The ground truth for the clinical evaluation was established by a "reference method". The specific nature of this reference method is not detailed, but for HbA1c assays, it typically refers to a highly accurate laboratory method (e.g., HPLC or mass spectrometry, often NGSP-certified) used to provide the true HbA1c values against which the device's measurements are compared.
8. Sample Size for the Training Set
The document does not specify a sample size for a training set. Immunoassays like the SD A1cCare System typically use a different development and validation paradigm than machine learning models that require distinct training and test sets. While the system may have undergone internal calibration and optimization during development, the text does not refer to a "training set" in the context of a machine learning algorithm.
9. How Ground Truth for the Training Set Was Established
As no "training set" in the machine learning sense is mentioned, this information is not available in the provided text. The calibration and performance optimization of an immunoassay system would typically be based on a series of characterized samples and reference methods, but this is not referred to as a "training set."

A drop of blood sample from the finger prick works with glucose oxidase and the mediators in the test strip to make a small electric current proportional to the glucose concentration in the blood. The meter reads the current and displays the blood glucose result equivalent to the current.
The user can search the stored results with three presentations of 7, 14 and 30-day averages of test results stored in memory: normal, pre-meal state averages. The system can set the beep, hypo warning, date, time, post-meal alarm. The system can also set the pre-meal and post-meal mark. Test results are displayed with mg/dL unit. A check strip allows the meter to check a problem and the control solution allows the meter and test strip to be checked.

The provided text describes the SD GlucoMentor™ Blood Glucose Monitoring System, but it does not contain detailed acceptance criteria or a study proving that the device meets specific performance criteria in the format requested.
The document is a 510(k) Summary, which typically focuses on demonstrating substantial equivalence to a predicate device rather than providing a standalone performance study with detailed acceptance criteria and results.
However, I can extract the information that is present and highlight what is missing based on your request.
Here's a breakdown of the available information and what's not present:
1. Table of Acceptance Criteria and Reported Device Performance
This information is not explicitly provided in the document. The document mentions types of testing performed (e.g., Performance Evaluation, Electromagnetic Compatibility Study (ISO 15197:2003)), but it does not specify the quantitative acceptance criteria (e.g., accuracy percentages, limits of agreement) or the precise reported device performance metrics against those criteria.
2. Sample size used for the test set and the data provenance
The document mentions:
- "A system accuracy evaluation (Method Comparison with Predicate Device) for the SD GlucoLink Blood Glucose Monitoring System was performed according to ISO 15197:2003."
- "A user performance study was performed to demonstrate that lay consumers could obtain accurate results using the SD GlucoLink Blood Glucose Monitoring System. The study was performed using capillary whole blood from fingertip, palm, forearm, and upper arm sample sites."
However, the specific sample sizes for these studies are not provided.
Data provenance (country of origin, retrospective/prospective) is also not specified. Given SD Biosensor, Inc.'s address in Korea, it's possible the studies were conducted there, but this is not stated. The studies appear to be prospective clinical studies based on the descriptions ("performed using capillary whole blood from...").
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not provided. For blood glucose monitors, the ground truth is typically established using a reference laboratory method (e.g., YSI analyzer). Certified laboratory personnel would operate such equipment, but they are not "experts" in the sense of clinical reviewers for imaging AI.
4. Adjudication method
This information is not provided. For blood glucose measurements, adjudication methods as described (e.g., 2+1) are not typically applicable. The reference method provides the established true value.
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
No MRMC comparative effectiveness study was done. This device is a blood glucose monitoring system, which does not involve "human readers" interpreting medical images or data that an AI would assist with in the traditional sense of an MRMC study.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Yes, the system accuracy evaluation is a standalone performance test of the device. The "user performance study" then tests the device with human-in-the-loop (lay consumers) to ensure they can obtain accurate results, but the primary measurement is algorithmic. However, the standalone performance metrics are not detailed.
7. The type of ground truth used
The ground truth for blood glucose monitoring systems is typically established using a reference laboratory method, such as a hexokinase-based enzymatic method performed on a YSI analyzer or similar highly accurate laboratory instrument. While not explicitly stated as "YSI," the "system accuracy evaluation (Method Comparison with Predicate Device)" implies comparison against a highly accurate reference.
8. The sample size for the training set
This information is not applicable/not provided. Blood glucose monitoring systems typically rely on established electrochemical principles calibrated during manufacturing; they are generally not "trained" on large datasets in the way a machine learning algorithm for image analysis would be.
9. How the ground truth for the training set was established
This information is not applicable/not provided for the reasons mentioned in point 8.
Summary of Missing and Provided Information:
Information Requested | Status in Document |
---|---|
1. Acceptance Criteria Table | NOT PROVIDED (only types of tests mentioned) |
2. Test Set Sample Size & Data Provenance | NOT PROVIDED (sample sizes) / Limited (provenance - likely prospective, possibly Korea) |
3. Ground Truth Experts & Qualifications | NOT APPLICABLE (ground truth usually from lab reference method, not clinical experts for adjudication) |
4. Adjudication Method | NOT APPLICABLE (not relevant for blood glucose measurements) |
5. MRMC Comparative Effectiveness Study & Effect Size | NOT APPLICABLE (not an AI-assisted interpretation device) |
6. Standalone Performance | Yes, implied by "System accuracy evaluation", but metrics not detailed. |
7. Type of Ground Truth | Reference laboratory method (implied, not explicitly named, e.g., YSI) |
8. Training Set Sample Size | NOT APPLICABLE (not an ML-trained device) |
9. How Training Set Ground Truth Established | NOT APPLICABLE (not an ML-trained device) |
This 510(k) summary focuses on demonstrating equivalence to an existing device rather than providing a detailed performance report with specific acceptance criteria and outcome data as might be found in a clinical trial publication.
