Please provide clinical details - eg, time taken in relation to anaphylatic reaction & list drugs taken.
APPLICATION: To identify anaphylaxis as a cause of collapse or death, eg, during anaesthesia, after insect sting, administration of drugs or biological agents (densitisation vaccines).
INTERPRETATION: Increasd tryptase levels indicate mast cell degranulation with mediator release, thereby demonstrating an allergic basis for the reaction. A negative result does not exclude an allergis basis.
