How do doctors scan for allergies? Like the specific what are they looking for in the body and how.

Disclaimer: The last time I was put through this process I was a kid, so it may be different now.
To test what I was allergic to I was put in a room with a nurse and she had tinctures of all different kinds of allergens in them in the form of a liquid. She had me hold my arms out and she dropped just a bit of each one in it’s own spot and the ones that make the skin red and irritated are deemed to be the things you are allergic to.
I am now wondering myself if there are other methods of doing this, especially for more severe types of allergies such as anaphylaxis.
