I can't tell exactly, the test was done on my forearm, I'd say about 20-something allergens. I think it was some kind of standard-test, because I didn't do a symptom diary or anything and she was using an adhesive tape with numbers on it to mark the spots for the according liquids she used to do the Prick-test (I want to say it looked like some kind of readymade "set" to test certain allergens).

The doctor is a medical specialist for lung-diseases and allergies.

I was thinking about using those bedcovers too. I just wasn't sure if it would make sense now that I'm officially tested as "non-allergic".
