Diagnosis

Your doctor may diagnose systemic mastocytosis through blood or urine tests or imaging tests like X-rays, ultrasounds, and CT scans. You may need a test to collect a sample of bone marrow to study in a lab. These tests look for high levels of mast cells or the substances they release.

Treatment

Treatment for systemic mastocytosis may include medications like antihistamines, aspirin, and drugs that work against the substances released by mast cells in your body. If you have a severe allergic reaction, you may need an injection of epinephrine. Aggressive forms of systemic mastocytosis may need powerful chemotherapy drugs to destroy mast cells.
