Order Tryptase Level Test | Mastocytosis TestingTryptase is a serine protease stored primarily in the secretory granules of mast cells and released when those cells degranulate. Measuring the level of tryptase in the blood provides a laboratory window into mast cell activity, which is why the assay is used both in the evaluation of severe allergic reactions and in the diagnostic workup of mast cell disorders such as mastocytosis.
About Tryptase Level Test | Mastocytosis Testing in Bothell
The Tryptase Level test quantifies the concentration of tryptase in a blood sample to assess mast cell burden and activation.
Tryptase exists in several forms. The mature enzyme is stored in mast cell granules and released during degranulation, while a precursor form is continuously secreted at low levels by mast cells. A total tryptase measurement captures both fractions, so an elevated result can reflect either an acute release event or a chronically increased number of mast cells.
Because tryptase is relatively specific to mast cells, it is a useful marker when anaphylaxis is suspected. Serial sampling can show the characteristic rise and fall that follows an acute event, and comparing a peak value with a later baseline sample helps distinguish a transient reaction from a persistent elevation.
Persistently elevated tryptase levels raise the possibility of systemic mastocytosis, a condition in which abnormal mast cells accumulate in tissues. The test is therefore used alongside clinical findings and, when indicated, bone marrow evaluation to support or refute that diagnosis. Results should always be interpreted by a qualified clinician in the context of the patient's history and other laboratory data.
