I'm not 100% positive about this but the blood test doesn't check for food allergies. If you want to test for food related allergies you need to do the patch test and it is more extensive so it is also more expensive.

The next step in treatment should be a serum created from the allergens specifically for your dog. Then you will start giving injections.

I did some quick research on HYDROXYZINE. Some interesting information pasted from various sites:

{It is an antihistamine and does not contain any cortisteriods. Antihistamines in general are more effective in itchy cats than itchy dogs though many dogs achieve relief with this medication. The enteric coating and small sized tablet make it a common first choice in an antihistamine trial.

In the treatment of allergic skin disease, antihistamines are felt to synergize with omega 3 fatty acid supplements and, as a general rule for this condition, it is best to use these medications together.

Hydroxyzine should not be used with additional tranquilizing medications.

A newer antihistamine called Cetirizine has become available. This medication represents an active form of hydroxyzine which does not cross the blood-brain barrier. This means that Cetirizine would be helpful for a patient who’s responded well to hydroxyzine but had an unacceptable level of drowsiness.

CONCERNS AND CAUTIONS

This medication will interfere with allergic skin testing. Check with your veterinary dermatologist regarding how far in advance this medication should be withheld.}


When I first started out with allergies in Dusty we did food elimination diets and he was started on Chlorphenaramine (antihistimine). We tried several antihistimines but none really worked. Then we started on the Prednisone. He needed to be off all these for a minimum of 3 weeks but preferrably 6 weeks before being blood tested. I only mention this because you said your vet did not tell you this. Before spending money on having a special allergy serum created, verify with the vet that the tests are valid if Nova was still on antihistimines immediately prior to the test being taken. While they probably are, it is better to check than to be sorry later after many dollars are invested. It never hurts to ask the vet!
