Transient tryptase concentrations greater than or equal to 11.5 ng/mL may be consistent with mast cell activation in the context of anaphylaxis or allergen challenge; measurement of tryptase in specimens obtained 1 to 6 hours and at least 24 hours after the episode may be useful in demonstrating a return to baseline concentrations. Mastocytosis encompasses a heterogeneous group of diseases characterized by the presence of clonal mast cells (MCs) in tissues and symptoms of MC activation, including anaphylaxis.

However, a wide range of symptoms has been reported among individuals with the associated syndrome, many of which can be rather common, so it is difficult to know who has it from symptoms alone. In MCAS, mast cells mistakenly release too many chemical agents, resulting in symptoms in the skin, gastrointestinal tract, heart, respiratory, and neurologic systems. Profile Information Reflex Tests Testing Algorithm For prenatal specimens only: If amniotic fluid (nonconfluent cultured cells) is received, amniotic fluid culture will be added at an additional charge. Circulatory system doctors (vascular medicine specialists) are trained to diagnose, treat, and manage diseases involving the vessels that move blood around the body (arteries, veins, and capillaries). Hereditary alpha tryptasemia syndrome could be present in a subset of patients with mast cell activation syndrome BUT they do not have a clonal mast cell disorder. Note, GARD cannot enroll individuals in clinical studies. After incubation, unbound enzyme-labeled antibodies are washed away, and the bound complex is incubated with a developing agent. Again, it must be stressed that there is great variability from person to person in terms of what symptoms the duplications or triplications do or do not cause.
