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 gives clinicians a biochemical window into mast cell activity, which is useful both in acute allergic events and in the evaluation of disorders characterized by abnormal mast cell accumulation.
About Tryptase Level Test | Mastocytosis Testing in Maple Valley
The Tryptase Level Test assesses circulating tryptase to support the investigation of mast cell–driven conditions.
Tryptase exists in two principal forms: alpha-tryptase, which is constitutively secreted and serves as a marker of total mast cell burden, and beta-tryptase, which is stored in granules and released during degranulation. A blood measurement captures the combined contribution of these forms, so the result must be interpreted alongside the clinical context in which the sample was drawn.
In anaphylaxis, tryptase typically rises within minutes of symptom onset, peaks around one hour, and declines over several hours. Because of this kinetics, the timing of collection relative to the event materially affects the result. A baseline tryptase obtained when the patient is well can later be compared with an acute value to determine whether the elevation is meaningful.
Persistently elevated baseline tryptase raises suspicion for mastocytosis, a group of disorders in which mast cells accumulate in tissues such as skin, bone marrow, and internal organs. The test is one component of a broader diagnostic workup that may include a complete blood count, bone marrow examination, and genetic testing for KIT mutations.
