Diagnosing mast cell activation disease (MCAS, MCAD, Dr. Afrin)

This is a good quote from Dr. Afrin, from this page about diagnosing mast cell activation disease (MCAS, MCAD), which explains why it has taken this long to get close to a diagnosis of my illness. Regular everyday doctors, even the hematologist I saw last week, may know about mastocytosis, but they don’t know about mast cell activation disease.
