Diagnosis
Diagnosing MCAS can be challenging due to its wide range of symptoms and lack of specific diagnostic tests. Doctors typically rely on a combination of:
- Medical history: Detailed review of symptoms and potential triggers
- Physical examination: Assessment for physical signs of mast cell activation
- Blood tests: Elevated tryptase levels or other markers of mast cell activation
- Bone marrow biopsy: May show increased mast cell count or abnormal mast cell morphology
Treatment
Treatment for MCAS aims to control mast cell activation and relieve symptoms. Options may include:
- Avoidance of triggers: Identifying and avoiding known triggers
- Antihistamines: H1 and H2 blockers to block histamine effects
- Mast cell stabilizers: Medications that prevent mast cells from releasing mediators
