Serum tryptase is raised acutely in anaphylaxis. It is particularly useful in anaesthetic allergy where it may help in the differential diagnosis of the acute reaction. However, normal levels do not exclude allergy as a cause of a reaction.

Read MoreSerum should be taken as soon as possible after the reaction (within 1 hour), a short time after the reaction (between 1 and 4 hours), as well as 24 hours later and labelled with the time of reaction and time of sample post reaction. The two samples taken give information about levels of Tryptase immediately post reaction and also once a resting level has returned. It is therefore very important that BOTH samples are taken, labelled accurately and sent to the laboratory quickly.
