2. Sample Size Used for the Test Set and Data Provenance
- Dimensions: 13 pieces of gloves from each size (XS, S, M, L, XL) for each parameter (length, width, thickness). Lot size for sampling was 35,001 to 150,000, with an inspection level of S-2 and AQL of 4.0.
- Freedom from Holes: 200 pieces of M-size gloves. Lot size for sampling was 35,001 to 150,000, with an inspection level of G-1 and AQL of 2.5.
- Physical Properties: 13 pieces of M-size gloves. Lot size for sampling was 35,001 to 150,000, with an inspection level of S-2 and AQL of 4.0.
- Powder-free Residue: 5 pieces of gloves.
- Skin Irritation Test: 6 New Zealand White rabbits (3 for polar extracts, 3 for non-polar extracts).
- Skin Sensitization Test: 30 guinea pigs (5 for polar solvent control, 10 for polar test item extract, 5 for non-polar solvent control, 10 for non-polar test item extract).
- In vitro Cytotoxicity: L-929 mouse fibroblasts cells.
- Acute Systemic Toxicity Test: 20 Swiss Albino mice (4 groups of 5 males each).
Data Provenance: The document does not explicitly state the country of origin for the testing facilities or the specific animal vendors/data source, but the submitter is from Malaysia. These are prospective tests performed specifically for this 510(k) submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts
These tests are standardized laboratory and in-vivo animal tests, not typically requiring "experts" in the sense of clinical reviewers establishing ground truth for diagnostic or AI systems. The "ground truth" is established by the well-defined and validated methodologies of the ASTM and ISO standards themselves. The results are quantitative measurements or qualitative observations by laboratory personnel trained in those specific methods.
4. Adjudication Method for the Test Set
Not applicable in the context of these types of performance and biocompatibility tests. Results are generally objective measurements or direct observations against a standard, not requiring multi-expert 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 device is an examination glove, not an AI/ML-based diagnostic system.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This device is an examination glove, not an AI/ML-based diagnostic system.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for these tests is based on:
- Standardized measurement protocols: For physical dimensions, tensile strength, elongation, and powder residue.
- Defined biological reactions: For freedom from holes (water leak detection) and biocompatibility tests (observed biological responses in animals or cell cultures according to ISO guidelines).
8. The Sample Size for the Training Set
Not applicable. This is not an AI/ML device, so there is no training set in the typical sense. The performance characteristics of the glove are inherent to its manufacturing process and material properties, validated by testing against established standards.
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set for this type of device.
