What does it mean to get an allergy test? what happens during an allergy test?

Skin prick/lab test: To be checked for allergy, usually you have a skin prick test to introduce a small amount of the allergen into the superficial layer of your skin (often done on your back or forearm). Alternatively, sometimes a blood test is checked instead to check for allergic antibody specific to an allergen (example, milk or dog dander).

To check for allergy: If you think you are allergic to something then an allergist takes your history and examines you. Then scratch testing is usually done on the skin - without needles. Not really painful. A drop of possible allergic substances is put in the skin. If you have an allergy a small welt- like a mosquito bite shows up. The allergist then interprets that along with your history.
