It all makes sense now

Nothing hits me like a case of strep. It rips through me and puts me down for weeks, but anything else and I bounce back in a day. Strangely though, the quick strep test never comes back positive. The docs just put me on penicillin because it is very obvious that I do have it and then later the long test confirms it.

I just learned that the quick test does not actually test for strep directly, it tests for the antibodies you are supposed to produce to fight it. Making a small leap I take this to mean that I don't produce enough, if any, of the strep antibodies on my own, which is why it hits me so hard and it takes me so long to get over it. My immune system works great against anything else, but just can't see strep.
