Are allergic tests for cats definitive? Will the test be done for all for major allergens known in cats?

In brief: Depends

There are two materials used for cat allergy testing - hair & skin.
Both contain the major cat allergen. Cat skin contains other allergens - especially cat Albumin - not present in cat hair - that sometimes cause allergic symptoms. So if you were tested only with cat hair perhaps you could be retested with cat skin (aka cat epidermal or cat dander).

Cat hair testing material usually contains the 2 major cat allergens, Fel d1 (from sebaceous glands) and Fel d4 (from salivary glands). If you have a strong history of reaction to the cat, and the cat hair test is negative, you may want to test with the cat pelt which may contain the minor antigens. You may also be allergic to outdoor pollen/molds that the cat may carry in house from outside.

In brief: Cat allergy test

Like any test, cat allergy test results have to correlate with the patient's history.
They can be falsely positive and negative.

In brief: CAT ALLERGIES

There are skin tests and blood tests for possible cat allergies.
Your general doctor or allergist will be able to explain these to you. These tests are not 100% correct.
