Order Tryptase Level Test | Mastocytosis TestingTryptase is an enzyme stored in mast cells, the immune cells that release histamine and other mediators during allergic reactions. Measuring tryptase levels in the blood gives clinicians an objective view of mast cell activity, which is useful when symptoms suggest anaphylaxis or a mast cell disorder such as mastocytosis.
About Tryptase Level Test | Mastocytosis Testing in Foster City
Tryptase testing is most often ordered when a severe allergic reaction is suspected or when a clinician is evaluating persistent symptoms that point to excess mast cells.
Tryptase exists in two main forms. Alpha-tryptase is released continuously at low levels by mast cells, while beta-tryptase is stored in granules and released in larger amounts when mast cells are activated. A total tryptase measurement reflects both forms, so the result is interpreted alongside the timing of symptoms and the clinical picture.
During anaphylaxis, tryptase levels typically rise within 15 to 120 minutes of symptom onset and can remain elevated for several hours. Because of this pattern, a sample collected too early or too late may miss the peak. When anaphylaxis is the concern, clinicians sometimes compare a sample drawn during the reaction with a baseline sample taken later, when the person is well, to see whether the level returns to normal.
In mastocytosis, abnormal mast cells accumulate in tissues such as the skin, bone marrow, or internal organs. Many people with systemic mastocytosis have a persistently elevated baseline tryptase, which is one of the minor diagnostic criteria used in evaluation. A normal tryptase does not by itself rule out a mast cell disorder, and an elevated result does not confirm one; the test is one piece of a broader assessment that may include a bone marrow examination and other laboratory studies.
