It seems like there are so many things to potentially be allergic to. How does/could a lab determine what someone is allergic to?
In:
Most allergy tests are not done at labs but at an allergist’s office. They don’t test you for every possible allergen in existence, that would be impossible, as you pointed out. They just test you for a few dozen of the most common allergens by using a skin prick to apply small amount of it to your skin to see if you have a reaction. You’ll only be tested for uncommon allergens if you have a specific complaint or symptoms that indicate an allergy to that substance.
