The Allergy Screening Tryptase Diagnostic Test is a crucial blood test used to measure the levels of tryptase, an enzyme primarily released by mast cells during severe allergic reactions. It serves as a vital biomarker to confirm cases of systemic anaphylaxis, helping clinicians differentiate life-threatening allergic responses from other medical emergencies.

Beyond acute episodes, this test is instrumental in diagnosing mast cell activation syndrome (MCAS) and mastocytosis—a rare disorder characterized by an abnormal accumulation of mast cells. Measuring both baseline and peak tryptase levels provides healthcare professionals with essential data to assess allergic severity and guide long-term management strategies.
