What ISO 10993-10 Sensitization Testing Means for Glove Buyers
A dental office that has one hygienist reporting itchy hands after a shift is dealing with a materials question, not a staffing question. Repeated skin contact with a device material can produce sensitization, which is a change in how the immune system reacts to something it has met before. ISO 10993-10 is the part of the biocompatibility series that describes how that risk is tested.
What the standard looks at
ISO 10993-10 sets out test approaches for skin sensitization, using defined extracts or material samples and defined observation periods. In the 2021 edition, the standard is dedicated to sensitization. Irritation, which was previously covered in the same part, now sits in ISO 10993-23 as a separate document. Knowing that split matters when a supplier hands over a report, because a current file should reference both parts.
Where this sits in the ISO 10993 series
- Part 1: evaluation and testing within a risk management process
- Part 5: cytotoxicity, the first screen for cell-level effects
- Part 10: skin sensitization
- Part 23: irritation
- Part 7: ethylene oxide residuals for items sterilized with EO
A clinic does not need to read all of them. What matters is that a supplier can say which parts were applied, why, and what the outcome was for the material touching skin.
Reading a report properly
| Item to find | Why it matters |
|---|---|
| :-- | :-- |
| Test method and extract medium | Shows what was actually tested |
| Material or finished device | A raw material result is not a device result |
| Observation period | Sensitization needs a repeat-exposure window |
| Conclusion, with limits | States what the result does not cover |
| Report date and revision | Older files may reference superseded editions |
Why this matters for gloves and dressings
Gloves sit on skin for hours, and staff wear them every day. Reactions reported after glove use can come from the polymer, from residual process chemicals, or from powder and donning agents. A sensitization report narrows the possibilities. For a clinic, the practical value is being able to change one variable at a time instead of switching product lines blindly.
What to keep on file
Keep the report, the material description and the lot or batch reference from your supplier. If several glove formats are stocked, keep a report for each one, since the material and the process differ between a 4 mil exam glove and a 5 mil textured glove.
For daily clinic use, a standard blue exam glove (4 mil nitrile exam gloves) covers routine examinations, a chemo-rated format (Aurelia Protege 4.0 mil gloves) suits handling where chemical exposure is a factor, and a fully textured glove (Aurelia Robust 5.0 mil gloves) helps with grip in wet work. Clinics trialling formats before a case order can start with the wholesale account.

Frequently Asked Questions
What does ISO 10993-10 test for?
It sets out how to test a device or material for skin sensitization, the immune response that develops after repeated exposure. In the current edition the standard is focused on sensitization, while irritation testing is described separately in ISO 10993-23.
Which products need this testing?
Materials that contact skin repeatedly, or that contact broken skin and mucosa, are the main candidates. Examination gloves, wound dressings and patient contact fabrics are common examples in a clinic setting.
How should I read a sensitization report?
Look for the test method used, the extract or material tested, the animal or in vitro model, the observation period and the conclusion. A report that names the method and the material is useful; a one-line statement that a product is non-irritating is not.
Do I need this report for gloves?
It helps when a clinic has staff or patients reporting reactions. Keeping the report with the lot documentation means a skin complaint can be handled with evidence rather than guesswork.
