Blood Testing
"Blood tests for allergies do seem to have some value in ruling out an allergy to a particular substance. That is, when test results come back saying that your pet is not allergic to something, it probably isn’t allergic to that substance. If it comes back stating that your pet is allergic to something, that may or may not be true."
