Technically, they're part of your immune and neuroimmune system, but as far as I know MCAS isn't classified as an autoimmune or immune system disease/disorder.

Promethazine in Germany is prescribed for anxiety, and they want you to see a psychiatrist to get it typically (despite the fact it's almost impossible to see a psychiatrist here in Germany). After taking promethazine during a coughing fit, the symptom magically cleared up. It turns out that promethazine, whilst prescribed for anxiety due to its sedative effects, is actually a powerful first generation anti-histamine. A cough after eating that gets cleared up by taking an antihistamine, how curious?"

Since these are the primary markers, you might be forgiven for thing it might be several hours or a couple of days, but, ha, no, it's 30-45 minutes. It usually takes you that long just to get in to get blood drawn, let alone analysed within that timeframe (or properly stored and defrosted to test later). Also, weirdly hospitals don't seem to test for these when you're showing signs of an MCAS attack, but they test everything else. (Don't ask me how I know..)"
