Take steps toward getting a diagnosis by working with your doctor, finding the right specialists, and coordinating medical care. It is also possible that the increased tryptase itself causes the symptoms without requiring mast cells to be activated, or it could cause an abnormally increased response to otherwise normal mast cell activation, which might explain why so many patients respond to medications that target mast cells and substances released by mast cells. Direct bilirubin ULN for patients with total bilirubin >1.5 x ULN. Previous Grade 3-4 infusion or hypersensitivity reaction (not immunotoxicity) to treatment with another mAb. Learn about symptoms, cause, support, and research for a rare disease. Elevated serum tryptase is present in perhaps up to 6 percent of the general population.
