Tryptase Level

Tryptase Level. If the tryptase blood test results indicate that the TMR is above 20 the medical provider will typically order a bone marrow aspiration. Tryptase measurement is of value in the assessment of selected cases of anaphylacticanaphylactoid reactions and in the investigation of suspected mastocytosis.

Tryptase levels can also be significantly and persistently increased with mastocytosis a rare group of disorders associated with an abnormal increase in the number of mast cells. If the tryptase level is persistently elevated then the person likely has a persistently increased number of mast cells. Elevated Tryptase level and not its dcrease is important in diagnosis of mast cell activation disorders Therefore decreased level of tryptase has no clinical importance.

Mast cell tryptase MCT is a key diagnostic test for mastocytosis and anaphylaxis. On average most people have a blood level of tryptase from 3 to 5 nanograms per milliliter ngmL. Mast cell tryptase MCT is a key diagnostic test for mastocytosis and anaphylaxis. These cells may accumulate in the skin cutaneous mastocytosis or in organs throughout the body systemic mastocytosis.
