The Sensitization Test is used for the determination of sensitizing activity of chemicals and medical devices. These tests are assessing the potential of a material or product to cause a delayed hyper-sensitivity reaction.

The sensitization test exposes the animals to the test article extracts or test article across multiple induction phases, and a single challenge phase. The challenge sites of each animal will be observed for evidence of skin sensitizations reactions 24±2 and 48±2 hours after removal of the test articles/extracts. Sensitization reactions are noted by observing erythema and/or edema (redness and swelling) as it interacts with the body’s immune system. Our Sensitization and Hypersensitivity Testing is performed in compliance with criteria from:

  • ISO 10993-10
  • ISO 10993-12
