A 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. These gloves were tested for use with Chemotherapy Drugs and Fentanyl Citrate as per ASTM D6978-05 (Reapproved 2019) Standard Practice for Assessment of Medical Gloves to Permeation by Chemotherapy Drugs.
Non-Sterile Nitrile Patient Examination Glove is made from synthetic rubber latex. It is single use and powder-free class I Nitrile Patient Examination Gloves which coated by on-line polymer with mild on-line chlorination process. These processes modify the surface characteristics and causes it to remain tack-free without the use of any dusting or donning powder. The available sizes are X-Small, Small, Medium, Large and X-Large. The Nitrile Examination Gloves Powder Free (Blue & Black) have been tested for Chemotherapy Drugs. The subject devices are identical in design and formulation to the predicate gloves of K230121.
The provided FDA 510(k) clearance letter pertains to Nitrile Examination Gloves Powder Free Tested for Use With Chemotherapy Drugs & Fentanyl Citrate (Blue & Black), a medical device. This type of device is classified as a Class I medical device and does not involve AI/ML technology. Therefore, many of the requested categories related to AI/ML device studies (e.g., sample sizes for test/training sets, ground truth establishment, MRMC studies, standalone performance, expert qualifications, adjudication methods, effect sizes) are not applicable.
The acceptance criteria and device performance are primarily evaluated based on material properties, chemical permeation resistance, and biocompatibility, using established ASTM and ISO standards for examination gloves.

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the exact sample sizes for each test (e.g., number of gloves tested for permeation, holes, dimensions, etc.) but refers to adherence to the methodologies outlined in the specified ASTM and ISO standards. These standards typically define minimum sample sizes for material testing.
- Data Provenance: The document states the applicant is from Malaysia (Careglove Global Sdn. Bhd.). The testing was conducted according to international standards (ASTM, ISO), implying the tests were performed in a controlled laboratory environment, likely by the manufacturer or a contracted lab. The data is non-clinical and derived from prospective testing of manufactured glove samples.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This device is not an AI/ML device that requires expert review for "ground truth" establishment in the context of diagnostic or interpretive tasks. The "ground truth" for material properties is established by the physical and chemical measurements themselves, according to standardized protocols and certified laboratory equipment.
4. Adjudication Method for the Test Set
Not applicable. This device is not an AI/ML device that requires adjudication for interpretations. Test results are objective measurements against predefined criteria.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
Not applicable. MRMC studies are relevant for diagnostic or interpretive AI/ML devices where human readers' performance is evaluated with and without AI assistance. This is a physical and chemical barrier device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Study Was Done
Not applicable. This device is a passive physical barrier and does not involve any algorithms or software.
7. The Type of Ground Truth Used
The "ground truth" for this device is based on objective measurements of physical properties (e.g., length, thickness, tensile strength, elongation), chemical resistance (breakthrough detection time), and biological reactivity (biocompatibility tests), as defined by internationally recognized standards (ASTM, ISO). There is no subjective human "ground truth" in this context.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/ML device that undergoes "training."
9. How the Ground Truth for the Training Set Was Established
Not applicable. This is not an AI/ML device. The manufacturing process of the gloves is designed to meet the specified standards, and quality control ensures consistency, but this is not "training" in the context of AI/ML.
§ 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.
