Total serum tryptase is elevated in mast cell leukemia. Normal total (alpha + beta) serum tryptase is approximately 6 micro g/L (range 0 to 11 micro g/L). Values of several hundred micro g/L are characteristic of mast cell leukemia. [12] Plasma and urinary histamine levels are frequently elevated in mast cell leukemia.
Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. [1] MCAS is an immunological condition in which mast cells, a type of white blood cell, inappropriately and excessively release chemical mediators, such as histamine, resulting in a range of chronic symptoms, sometimes including anaphylaxis or ...

[1] [2] Metabolically, hypertryptophanemia results in tryptophanuria and exhibits significantly elevated serum levels of tryptophan, exceeding 650% of maximum (normal range: 25–73 micromole/l) in some instances. [2] [3] A product of the bacterial biosynthesis of tryptophan is indole.
If the base level of s-tryptase is elevated, this implies that the mastocytosis can be systemic. In cases of suspicion of SM help can also be drawn from analysis of mutation in KIT(D816V) in peripheral blood using sensitive PCR-technology [citation needed] To set the diagnosis of systemic mastocytosis, certain criteria must be met.
