Allergy Scratch Test

Welcome to Healingwell No, the scratch test shouldn't hurt. It feels sort of like when you run the corner of your finger nail down your arm. Usually they test you for the typical allergens such as pollen, molds, mildew, dust, dustmite, cat, dog etc. If you have a positive reaction, the skin where it was scratched will get red and sort of puffy. If there is no reaction, nothing will show up on the skin. I can't remember exactly since it was a long time ago that my son had this done, but they use a scale I believe. If it falls within a certain range, then it shows an allergy. (someone correct me if I'm wrong here)

Also, they usually do them on your back, but I just had one done a few months ago and they did it on my upper arm. It doesn't hurt to get the test. If you end up being allergic to one of the allergens they test, it can make you itchy for a little while in that spot...nothing too bad. They do tell you not to itch it at all though while you're waiting for about 10 minutes to see what (if any) reactions you have.
