Answer:
Allergists, docs who specialize in this, do skin prick tests to check for allergic responses. It's mildly painful.

Answer:
A dermatologist can do scratch tests to see what you are allergic too
Just last week had one.
And if you’re allergic to cats i would not study veterinary technology at all.
But that is up to you of course.

Answer:
Allergies can often be diagnosed by a careful medical history, matching the onset of symptoms to the exposure to possible allergens. Allergy tests can be used to identify potential allergens. These tests usually start with prick tests or patch tests, which expose the skin to small amounts of allergen to observe the response. Reaction will occur on the skin even if the allergen is normally came across in food or in the airways. RAST testing is a blood test that measures the level of reactive antibodies in the blood. Provocation tests, most commonly done with airborne allergens, present the allergen directly through the route normally involved. Food allergen provocation tests require abstinence from the suspect allergen for two weeks or more, followed by ingestion of a measured amount. Provocation tests are not used if anaphylaxis is a concern due to the patient's medical history.
