Tryptase Unit Converter

Tryptase is an enzyme stored in the granules of mast cells, which are immune cells found throughout your body. When mast cells are activated, they release tryptase along with other substances like histamine.

There are two main forms: alpha-tryptase (constantly released in small amounts) and beta-tryptase (stored in granules and released during allergic reactions or mast cell activation). Most laboratory tests measure total tryptase, which includes both forms.

Baseline tryptase reflects the total number of mast cells in your body, while acute tryptase (measured during or shortly after a reaction) indicates how much mast cell activation has occurred.

Tryptase is produced primarily by mast cells, which are found throughout the body in tissues such as the skin, airways, gastrointestinal tract, and bone marrow. Basophils (a type of white blood cell) also produce small amounts of tryptase.
