I went to an Allergy clinic in a hospital and just got the entire test where they prick sample sites into your back (it doesn't hurt at all). I don't have my paper near me but I hit something like 80-85% of the allergens they tested me with which ran the gamut from pollens to bugs, a few common common foods (tomatoes/nightshades for sure, I forget what else) were also on the list although not that many.

IIRC it was either stupid cheap or covered by insurance. I was a little annoyed my parents didn't take me in when I was younger for it.

It was completely hassle-free and maybe 30 minutes.

Now when I eat pizza with tomato sauce and start scratching my arms and my mouth is burnt and my stomach is destroyed and I have wild brain fog for 3 days I finally know why! Not sure how I never equated it before, I always thought it was the bread and never got gluten tested (could still contribute, but I'm not going through that test).

This is a dogs results but my results looked similar, I just had a food section; https://i.servimg.com/u/f11/18/49/47/07/kyeall11.jpg
