What is Anti-Tryptase?

This blood test is used to measure the concentration of tryptase that has been released into the blood by mast cells. Tryptase is an enzyme which gets released into the blood as a result of an allergic immune response. This test is used to detect conditions like anaphylaxis, mastocytosis, and other allergic conditions.

Why is Anti-Tryptase done?

This test is usually suggested if you have recurrent symptoms that may resemble anaphylaxis or mastocytosis, like swollen face, itchy skin and others.

Interpreting Anti-Tryptase results


If a high tryptase level reduces suddenly, then it is an indicator of anaphylaxis. If the tryptase levels shoot up and don’t reduce for a long period, then it is an indication of mastyocytosis.
