Are blood allergy tests for pets accurate?

Serum allergy test is less invasive than the skin test. It is very important this test be done at the right time for each pet – if the test is run at the wrong time it may be negative despite the patient being allergic. This blood is taken in-clinic and the test is done at an outside lab. The only reason to do allergy testing in a pet is to use the results to begin immunotherapy and desensitize your pet to their environmental allergies.
