Mast cell activation syndrome must meet consensus criteria. A serum level greater than 10 ng/ml is suggestive of alpha tryptasemia, while a level lower than 8ng/ml makes this diagnosis far less likely. Finding a doctor you can trust to provide you with the best options and course of treatment is a critical part of your health journey. Heritable risk for severe anaphylaxis associated with - PubMed It is also possible that the increased tryptase itself causes the symptoms without requiring mast cells to be activated, or it could cause an abnormally increased response to otherwise normal mast cell activation, which might explain why so many patients respond to medications that target mast cells and substances released by mast cells. This assay cannot be performed on chorionic villus specimens.

Tryptase, a neutral protease, is a dominant protein component of the secretory granules of human mast cells. In the case of hereditary alpha tryptasemia, people with this trait have inherited extra copies of the alpha tryptase gene (TPSAB1), and this leads to increased levels of trypase protein detected in the blood, whether a reaction is happening or not.
