TRYPT

Specialty

Allergy

Clinical significance

Tryptase is secreted almost exclusively by mast cells and is only found in the blood after these cells have been stimulated by some agonist, e.g. a drug or hymenopteran venom. Its levels correlate with the severity of the anaphylaxis (e.g. the case of curare). High levels are also found in systemic mastocytosis.
