ASTM D6124-06 (Reapproved 2017) | Determine residual powder in the gloves | 2 Mg/Glove Max | X-small: 0.3mg/glove, Small: 1.4mg/glove, Medium: 2 mg/glove, Large: 0.5 mg/glove, X-Large: 0.7mg/glove (All meet or are below 2 Mg/Glove) |
ISO 10993-10 (Irritation) | Determine potential for dermal irritation in Rabbits | Under the condition of study not an irritant | Under the condition of study not an irritant |
ISO 10993-10 (Sensitization) | Determine skin sensitization potential in Guinea Pig | Under the conditions of the study not a sensitizer | Under the conditions of the study not a sensitizer |
ISO 10993-5:2009 (In vitro cytotoxicity) | Evaluate in vitro cytotoxic potential | Under the conditions of study non cytotoxic | Under the conditions of the study cytotoxic (This is an interesting result, as it states "cytotoxic" where the acceptance criteria states "non cytotoxic". This typically requires additional justification or risk assessment for FDA clearance.) |
ISO 10993-11:2017 (Acute systemic toxicity) | Determine acute systemic toxicity potential in mice | Under the conditions of study, the device extracts do not pose a systemic toxicity concern | Under the conditions of study the device extracts do not pose a systemic toxicity concern |
ISO 10993-11:2017 (Material Mediated Pyrogenicity) | Determine pyrogenic potential in Rabbits | Under the conditions of the study, the device did not demonstrate a material mediated pyrogenicity response | Under the conditions of the study, the device did not demonstrate a material mediated pyrogenicity response |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document lists test methods (e.g., ASTM D6319-2019, ISO 10993 series) but does not specify the sample sizes used for each test for the subject device. It also does not specify the data provenance in terms of country of origin or whether the tests were retrospective or prospective. It only indicates that "Non-clinical tests were conducted to verify that the proposed device complies with the following standards".
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 product is a medical examination glove, which is a physical device, not an AI or diagnostic imaging product. Therefore, the concept of "experts" establishing a "ground truth" for a test set in the way it's described (e.g., radiologists for medical images) does not apply to this type of device. Performance is measured against established material and safety standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
The concept of an "adjudication method" (like 2+1 or 3+1 consensus) is relevant for studies involving human interpretation of data, particularly in diagnostics or AI algorithm validation. Since this document pertains to the physical and biocompatibility testing of a medical glove, this method is not applicable and not mentioned.
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 a physical medical device (examination glove), not an AI-assisted diagnostic tool. Therefore, an MRMC comparative effectiveness study is not applicable and was not performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Again, this is a physical medical device. The concept of "standalone algorithm performance" does not apply. The tests performed are on the physical and chemical properties of the glove itself.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For this type of device, "ground truth" is defined by the established ASTM and ISO standards for physical properties (like length, width, thickness, tensile strength, elongation, watertightness, powder residue) and biocompatibility (irritation, sensitization, cytotoxicity, systemic toxicity, pyrogenicity). These standards themselves represent a consensus on what constitutes acceptable performance for such a device.
8. The sample size for the training set
This is a physical medical device, not an AI algorithm. Therefore, the concept of a "training set" for machine learning does not apply and no training set was used.
9. How the ground truth for the training set was established
As there is no training set for this type of device, this question is not applicable.
§ 880.6250 Non-powdered patient examination glove.
(a)
Identification. A non-powdered patient examination glove is a disposable device intended for medical purposes that is worn on the examiner's hand or finger to prevent contamination between patient and examiner. A non-powdered patient examination glove does not incorporate powder for purposes other than manufacturing. The final finished glove includes only residual powder from manufacturing.(b)
Classification. Class I (general controls). The device, when it is a finger cot, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 880.9.
