Tryptase - Wikipedia
Tryptase is the most abundant secretory granule-derived serine proteinase in mast cells and a marker for mast cell activation. It is involved in allergenic response, influenza virus infection, and some diseases such as eosinophilic leukemia and systemic mastocytosis.

Measuring serum tryptase after suspected anaphylaxis
Acute elevation of serum tryptase indicates degranulation of mast cells which occurs either due to an IgE-mediated mechanism, for example with penicillin allergy, or may result from direct degranulation of mast cells through non-IgE-mediated means, for example with NSAIDs or …
