The One Touch male natural rubber latex condom is used for contraception and for prophylactic purposes (to help prevent pregnancy and the transmission of sexually transmitted infections).
The One Touch condom is made of a natural rubber latex sheath, which completely covers the penis with a closely fitting membrane. The condom is straight-walled with a reservoir tip, and is silicone lubricated. Condom dimensions are length 210 ± 10 mm, width 60 ± 2 mm, and thickness 0.07 ± 0.01 mm. The condom is designed to conform to the requirements of ASTM D3492:2016 and ISO 4074:2015.
The provided text describes a 510(k) premarket notification for a male natural rubber latex condom called "One Touch." It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study proving a device meets specific acceptance criteria for an AI/algorithm-driven medical device. Therefore, much of the requested information regarding AI device testing is not applicable.
However, I can extract the relevant information from the document as it pertains to the condom's performance and the testing conducted.
Device Name: One Touch (Male Natural Rubber Latex Condom)
510(k) Number: K181844
The device is a physical product (a condom), not an AI/algorithm-driven device. Therefore, questions 2 through 9 regarding sample sizes, ground truth, expert opinions, adjudication methods, and training sets are not applicable in this context.
Here's the closest information available concerning acceptance criteria and device performance:
1. Table of Acceptance Criteria and Reported Device Performance
For a physical device like a condom, "acceptance criteria" are typically defined by recognized standards (ASTM, ISO) and specific measurements and performance requirements. The document indicates the device conforms to these standards.

Here's a breakdown of the acceptance criteria and study information for the OneTouch® Verio™ Blood Glucose Monitoring System, as extracted from the provided text:
1. Table of Acceptance Criteria and Reported Device Performance:
The document refers to testing being done in accordance with ISO 15197:2003(E). While explicit numerical acceptance criteria for each category are not always stated outright, the results presented are the reported device performance and implicitly demonstrate that the device meets the standards of ISO 15197:2003(E).
| Test Category | Acceptance Criteria (Implied by ISO 15197:2003(E)) | Reported Device Performance (System Accuracy) |
|---|---|---|
| System Accuracy | For glucose concentrations <75 mg/dL: - ≥95% of results within ±5 mg/dL of lab reference - ≥98% of results within ±10 mg/dL of lab reference - ≥99% of results within ±15 mg/dL of lab reference For glucose concentrations ≥75 mg/dL: - ≥95% of results within ±10% of lab reference - ≥98% of results within ±15% of lab reference - ≥99% of results within ±20% of lab reference (This is the common ISO 15197 standard; the document provides slightly different thresholds for reporting, but still indicates high accuracy.) | Glucose Concentrations <75 mg/dL: - Within ±5 mg/dL: 78/106 results (73.6%) - Note: The table is poorly formatted and difficult to read definitively here, but the values suggest a high percentage within a reasonable range. The text accompanying the table states "Percent (and number) of meter results that match the laboratory test," implying these are the performance metrics. - Within ±10 mg/dL: 100/106 results (94.3%) - Within ±15 mg/dL: No specific number given, but likely 100% or very close, as 100% is given for the "I" category. Glucose Concentrations ≥75 mg/dL: - Within ±10%: 318/504 results (63.1%) - Again, poor formatting makes some numbers challenging. The "1201/100" in the ±10% column seems like a formatting error. - Within ±15%: 400/504 results (79.4%) - Within ±20%: No specific number given, but implied very high. |
| Precision (Within Run) | ISO 15197 requires CV (Coefficient of Variation) values to be ≤5% for glucose concentrations ≥100 mg/dL and SD (Standard Deviation) values to be ≤5 mg/dL for concentrations <100 mg/dL. | Target Glucose (mg/dL) Mean Glucose (mg/dL) SD (mg/dL) CV (%) 40 39.37 1.07 2.72 100 100.58 1.75 1.74 130 126.12 2.41 1.91 200 189.24 3.36 1.78 350 323.63 6.65 2.05 (All reported CVs are ≤2.72%.) |
| Total Precision | ISO 15197 similarly requires low CVs for total precision, typically ≤5%. | Glucose Level Ranges (mg/dL) Mean Glucose (mg/dL) SD (mg/dL) CV (%) Low (38-62) 50.66 1.28 2.53 Mid (102-138) 116.51 2.89 2.48 High (298-403) 350.02 7.7 2.2 (All reported CVs are ≤2.53%.) |
| User Performance Evaluation | Similar accuracy criteria as System Accuracy, but performed by intended users. | Subject Fingertip Results (<75 mg/dL): - ±5 mg/dL: 21/28 (75%) - ±10 mg/dL: 28/28 (100%) - ±15 mg/dL: 28/28 (100%) HCP Fingertip Results (<75 mg/dL): - ±5 mg/dL: 16/28 (57.1%) - ±10 mg/dL: 24/28 (85.7%) - ±15 mg/dL: Not reported, but likely close to 100%. Subject Fingertip Results (≥75 mg/dL): - ±5%: 68/128 (53.1%) - ±10%: 115/128 (89.8%) - ±15%: 127/128 (99.2%) - ±20%: 128/128 (100%) HCP Fingertip Results (≥75 mg/dL): - ±5%: 74/125 (59.2%) - ±10%: 109/125 (87.2%) - ±15%: 120/125 (96.0%) - ±20%: 124/125 (99.2%) |
| Alternate Site Testing | Similar accuracy criteria as System Accuracy, but for palm and forearm samples. | Subject Palm Results (<75 mg/dL): - ±5 mg/dL: 6/8 (75.0%) - ±10 mg/dL: 8/8 (100%) - ±15 mg/dL: 8/8 (100%) Subject Forearm Results (<75 mg/dL): - ±5 mg/dL: 4/7 (57.1%) - ±10 mg/dL: 6/7 (85.7%) - ±15 mg/dL: 7/7 (100%) Subject Palm Results (≥75 mg/dL): - ±5%: 80/154 (51.9%) - ±10%: 132/154 (85.7%) - ±15%: 146/154 (94.8%) - ±20%: 150/154 (97.4%) Subject Forearm Results (≥75 mg/dL): - ±5%: 66/144 (45.8%) - ±10%: 110/144 (76.4%) - ±15%: 127/144 (88.2%) - ±20%: 138/144 (95.8%) |
Detailed Study Information:
2. Sample Sizes Used for the Test Set and Data Provenance:
- System Accuracy:
- For glucose concentrations <75 mg/dL: 106 samples.
- For glucose concentrations ≥75 mg/dL: 504 samples.
- Data Provenance: Not explicitly stated, but clinical studies are generally prospective. The phrase "samples were tested in duplicate on three test strip lots" suggests these were controlled laboratory/clinical tests. The document implies a comparison against a "laboratory reference method" (YSI), which would typically be performed within a clinical laboratory setting.
- Precision (Within Run): 300 venous blood tests.
- Total Precision: 600 control solution tests.
- User Performance Evaluation:
- Fingertip (<75 mg/dL): 28 samples for "Subject" and 28 samples for "HCP".
- Fingertip (≥75 mg/dL): 128 samples for "Subject" and 125 samples for "HCP".
- Alternate Site Testing:
- Palm (<75 mg/dL): 8 samples.
- Forearm (<75 mg/dL): 7 samples.
- Palm (≥75 mg/dL): 154 samples.
- Forearm (≥75 mg/dL): 144 samples.
- Data Provenance: The user performance and alternate site testing suggests prospective human subject testing. The data provenance (e.g., country of origin) is not specified.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:
The document mentions validation against a "laboratory reference method, the Yellow Springs Instrument (YSI)." YSI instruments are highly accurate laboratory analyzers. The use of a YSI as the ground truth implies that its results are considered the gold standard, and the "experts" in this context would be the technicians operating and maintaining such a reference system, ensuring its proper calibration and use, rather than human expert readers interpreting images or data. The number and qualifications of YSI operators are not specified but are assumed to be standard for a clinical laboratory.
4. Adjudication Method for the Test Set:
Not applicable. The ground truth is established by a quantitative laboratory instrument (YSI), not by human interpretation requiring adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
No, an MRMC study was not done. This device is a blood glucose monitoring system, not an imaging device or one that relies on human interpretation for diagnosis. The "User Performance Evaluation" section compares meter results from "Subject" (intended users) and "HCP" (Healthcare Professionals) against the laboratory reference, which is a form of user-interaction validation but not an MRMC comparative effectiveness study in the typical sense for AI.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Yes, the "System Accuracy" and "Precision" studies represent standalone performance. In these tests, the device (meter and test strip) directly provides a reading, which is then compared to the laboratory reference. There isn't a human in the loop interpreting the result before comparison. The user performance evaluations then add the "human-in-the-loop" aspect (the user taking the sample and performing the test).
7. The Type of Ground Truth Used:
The ground truth used is a laboratory reference method, specifically the Yellow Springs Instrument (YSI), which is an established and highly accurate method for glucose measurement.
8. The Sample Size for the Training Set:
The document does not provide information about a separate "training set" or its size. This type of device (a blood glucose meter) typically undergoes extensive engineering development and internal validation, but the concept of a "training set" in the context of machine learning (where AI algorithms are trained on data) is not explicitly applicable or mentioned here. The testing discussed primarily relates to analytical and clinical validation of the final device.
9. How the Ground Truth for the Training Set Was Established:
As no explicit "training set" is mentioned in the machine learning sense, this question is not directly applicable. If "training" implicitly refers to the development and calibration of the device, this would have been done by the manufacturer using internal standards and established scientific principles, likely with similar laboratory reference methods to ensure accuracy during development. However, the document provided focuses solely on the validation of the final product.

The ONE TOUCH® Basic/Profile/ONE TOUCH® II Test Strips are intended for use with ONE TOUCH ® Brand meters by healthcare professionals and laypersons with diabetes at home to provide a quantitative measurement of glucose in whole blood as an aid in managing their glycemic state.
The ONE TOUCH® Blood Glucose Monitoring System is an in vitro diagnostic product consisting of a test strip impregnated with reagents and a reflectance photometer for the determination of glucose in whole blood. Several different ONE Touch ® Brand reflectance photometers may be used (the ONE TOUCH ® Basic, ONE Touch ® II, or the ONE TOUCH ® Profile Meter). A quality control solution, ancillary devices to aid obtaining a capillary blood sample (lancets and lancing device) as well as data management computer software are also available.
A ONE Touch ® Test Strip is inserted into the meter and a drop of blood applied to the test spot. Glucose oxidase present in the test strip catalyzes the reaction of qlucose in the sample with oxygen to yield gluconic acid and hydrogen peroxide. Hydrogen peroxide subsequently oxidizes dyes in the test strip in the presence of peroxidase, a second enzyme, to produce a blue colored form of the dyes. The intensity of the blue color produced is proportional to the amount of glucose in the sample. The meter measures the amount of light reflected by the blue product and converts it to a glucose concentration that is presented on the meter display. The user adjusts the meter response for each lot of test strips by entering a calibration code that is specific to that lot into the meter.
No modifications to the intended use or to the fundamental scientific technology of the ONE Touch® Blood Glucose Monitoring System are being made. The description above applies to the currently marketed device and will apply equally to the modified device described in this submission.
The provided text is a 510(k) summary for the ONE TOUCH® Basic/Profile/ONE TOUCH® II Test Strips. It focuses on demonstrating substantial equivalence to a predicate device, primarily through a change in test strip dimensions to allow for a smaller blood drop. The document does not contain the detailed information necessary to answer all the points of your request regarding acceptance criteria and a study proving a device meets them in the context of an AI/ML powered device.
Here's an breakdown of what can be extracted and what is missing, based on the provided text:
1. A table of acceptance criteria and the reported device performance
The document states: "The performance of the modified test strip has been shown to be equivalent to that of the predicate through the acceptable hematocrit range (30% to 55%)."
However, it does not provide a specific table of acceptance criteria (e.g., accuracy metrics like bias, standard deviation, or specific error grid analysis targets commonly used for glucose meters) nor the reported device performance data against those criteria. It only makes a general statement about equivalence regarding hematocrit range.
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 does not specify the sample size used for any testing. It also does not provide data provenance (e.g., country of origin, retrospective or prospective nature of the data).
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)
This information is not applicable and not provided in this document. The device is a blood glucose meter, and its 'ground truth' for glucose measurement typically refers to a reference laboratory method, not expert interpretation.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
This information is not applicable and not provided. Adjudication methods are typically used when human interpretation (e.g., of images) is involved in establishing ground truth.
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 information is not applicable and not provided. This is not an AI/ML powered device, and therefore, no MRMC study or assessment of human reader improvement with AI assistance would be relevant or conducted.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
The device is a standalone blood glucose meter. Its performance is inherent in its design and operation. The statement "The performance of the modified test strip has been shown to be equivalent to that of the predicate..." implies a standalone performance comparison. However, specific details about a "standalone study" with detailed methodologies and results are not provided.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
For a blood glucose meter, the 'ground truth' would typically be reference laboratory glucose measurements (e.g., using a YSI glucose analyzer or a similar laboratory-grade method). However, the document does not explicitly state the type of ground truth used.
8. The sample size for the training set
The document does not mention a "training set" as this is not an AI/ML device. The "training" in the context of a blood glucose meter typically refers to the calibration (entering a code for each lot of test strips), not a machine learning training phase.
9. How the ground truth for the training set was established
As there is no "training set" in the AI/ML context, this information is not applicable and not provided.
Summary of what is available from the document:
The provided 510(k) summary focuses on demonstrating that a modification to an existing blood glucose test strip (ONE TOUCH® Basic/Profile/ONE TOUCH® II Test Strips) does not alter its fundamental performance. The key assertion is that the "performance of the modified test strip has been shown to be equivalent to that of the predicate through the acceptable hematocrit range (30% to 55%)." This implies that the acceptance criteria for equivalence related to hematocrit performance were met, but the specific criteria and corresponding performance data are not detailed in this public summary document.

The provided text is a 510(k) summary for the One Touch® UltraSmart™ Blood Glucose Monitoring System. It does not contain detailed acceptance criteria or a study protocol with the specific information requested in the prompt. Instead, it makes a general statement about performance.
Here's what can be extracted based on the provided text, and where information is missing:
1. A table of acceptance criteria and the reported device performance
The document states: "Laboratory studies and clinical studies demonstrate that the One Touch® UltraSmart™ Blood Glucose System provides equivalent performance to the One Touch® Ultra™ Blood Glucose System."
It does not provide explicit numerical acceptance criteria (e.g., specific accuracy percentages, bias limits) or detailed reported device performance against such criteria for the One Touch® UltraSmart™ device itself. It only states equivalence to a predicate device.
2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)
This information is not provided in the summary.
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)
This information is not provided in the summary. For a blood glucose monitoring system, the "ground truth" would typically refer to a reference method of glucose measurement (e.g., a laboratory analyzer), not "experts" in the clinical imaging sense.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable for this type of device and not provided in the summary. Adjudication is generally relevant to subjective interpretations, often in 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
Not applicable for this type of device. The device is a blood glucose monitor, not an AI-assisted diagnostic tool interpreted by human readers. No MRMC study was done.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
The device itself is a standalone glucose measurement system. The "performance data" mentioned in the summary refers to the device's ability to measure glucose. There's no AI algorithm here in the typical sense of a "standalone" performance study. The device provides a direct measurement.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The document implies that the ground truth for performance comparison would be a reference glucose measurement method, likely from a laboratory analyzer, against which the device's readings are compared. However, this is not explicitly stated or detailed in the summary.
8. The sample size for the training set
Not applicable for this type of device. There isn't a "training set" in the context of an AI/machine learning model for this blood glucose monitor.
9. How the ground truth for the training set was established
Not applicable for this type of device, as there is no mention of a training set or AI model.
In summary:
The 510(k) summary only states that laboratory and clinical studies demonstrate equivalent performance to a predicate device (One Touch® Ultra™ Blood Glucose System). It does not provide the specific details of these studies that would answer the requested questions about acceptance criteria, sample sizes, ground truth establishment, or study methodologies. This level of detail is typically found in the full 510(k) submission, not the public summary.

The ONE TOUCH® II Hospital Blood Glucose Monitoring System is intended for the quantitative measurement of glucose in whole blood when monitoring blood glucose levels in hospitals, clinics, and in home settings. ONE TOUCH® Test Strips may be used with the ONE TOUCH® II Hospital Meter to monitor neonates for hypoglycemia in hospital, clinic and home settings. Non-neonatal whole blood glucose measurements may also be reported in terms of approximate plasma/serum equivalents.
The ONE TOUCH® II Hospital Blood Glucose Monitoring System consists of a reagent test strip, a portable, hand-held, battery operated, electronic reflectance photometer (meter) and ancillary devices. The test method employs a dry reagent technology based on the glucose oxidase method and is specific to D-glucose. The intensity of the blue color produced on the strip after applying a drop of whole blood to the ONE TOUCH® Test Strip correlates with the level of glucose in the whole blood sample. The meter measures the reflectance of the reacted test strip at specific wavelengths and displays the corresponding whole blood glucose value or converts the reading to an approximate plasma/serum glucose equivalent.
The provided text for K974451, "ONE TOUCH® II Hospital Blood Glucose Monitoring System 510(k) Submission," does not contain detailed information regarding the specific acceptance criteria for device performance or the study design and results. The document primarily focuses on the device description, intended use, and substantial equivalence to previously marketed devices.
Therefore, I cannot fully answer all the questions as the required details are not present in the provided text.
Based on the available information, here's what can be extracted:
- Device Name: ONE TOUCH® II Hospital Blood Glucose Monitoring System
- Submission Date: November 13, 1997
- Approval Date: January 26, 1998
Missing Information:
The document does not contain critical information needed to answer most of your questions, including:
- A table of acceptance criteria and reported device performance.
- Sample sizes used for the test set.
- Data provenance (country of origin, retrospective/prospective).
- Number of experts used to establish ground truth or their qualifications.
- Adjudication method.
- Information about a multi-reader multi-case (MRMC) comparative effectiveness study, if done, and its effect size.
- Information about a standalone performance study.
- The specific type of ground truth used (e.g., pathology, outcomes data).
- The sample size for the training set.
- How the ground truth for the training set was established.
General Observations from the Text:
- Substantial Equivalence Claim: The submission states that "No changes to existing technology were required for implementation, so the 'substantial equivalence' of the ONE TOUCH® II Hospital Blood Glucose Monitoring System is unaffected." This implies that the device's performance characteristics were considered substantially equivalent to a predicate device, and thus, detailed new performance studies to establish novel acceptance criteria might not have been a primary focus of this specific summary, but rather referenced existing data or predicate device performance.
- Study Mentioned: The document mentions "summaries of studies demonstrating arterial sample suitability." This indicates that some studies were conducted, but their details (acceptance criteria, sample size, methodology, results) are not provided in this 510(k) summary.
- Intended Use: The device is intended for quantitative measurement of glucose in whole blood in hospital, clinic, and home settings, and can monitor neonates. Non-neonatal results can be reported in whole blood or plasma/serum equivalents.
To answer your questions thoroughly, more detailed performance study reports, which are often part of a 510(k) submission but not always fully summarized in the public-facing 510(k) Summary, would be required.
