2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Sample size for test set: Not explicitly stated for each test (length, width, thickness, tensile strength, elongation, stress, pinhole). However, "Average Value of Subject Device" generally indicates testing was done on multiple samples.
  • Data provenance:
    • Country of origin: Testing was conducted by Lenora Glove Pvt. Ltd., located in Coimbatore, Tamil Nadu, India.
    • Retrospective or prospective: The document describes "bench tests" performed to verify the device met specifications, which indicates prospective testing of the manufactured product.

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 device is not an AI/diagnostic device that typically involves expert ground truth establishment in the same way. The "ground truth" for the performance characteristics comes from established international and national standards (e.g., ASTM D3577-09, ASTM D5151-06, ISO 10993-10). These standards define the acceptable range for physical and biological properties of latex surgeon's gloves. Therefore, there were no "experts" in the context of medical image interpretation for this type of device.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. As described above, the acceptance criteria are based on objective measurements against established engineering and medical device standards, not subjective interpretations requiring 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

Not applicable. This is a physical medical device (surgical glove), not an AI-assisted diagnostic tool or an imaging product. MRMC studies are not relevant here.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is a physical medical device, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for this device is defined by the acceptance criteria established in recognized consensus standards. These standards (e.g., ASTM, ISO) outline specific physical, mechanical, and biological properties that surgical gloves must meet for safety and effectiveness.

8. The sample size for the training set

Not applicable. This is a physical medical device, not an AI/machine learning model that requires a training set.

9. How the ground truth for the training set was established

Not applicable. No training set was used for this physical medical device.

Dear Manoj Zacharias:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

{1}------------------------------------------------

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
