Pseudoperoxidase Activity
Definition
Peroxide-dependent oxidation chemistry associated with haem proteins such as haemoglobin. Some screening reactions use haem-associated peroxide chemistry to reveal areas compatible with blood. Substrates and other catalysts can also affect the response.
- Context
- Blood screening
For example, peroxide-dependent screening chemistry can produce a useful response without uniquely identifying a body fluid or donor.
A positive reaction is not specific proof of human blood or a particular donor. Suitable follow-up and contamination controls are required.
