hi, after lots of money spent and vet visits, you should know that those blood test kits are bery inaccurate for food allergies. There sre lots and lots of false positives and negatives. The ONLY way to truly identify food allergy is by an elimination diet. This involves either feeding a novel protein source or a hydrolyzed diet like royal canin for 8-13 weeks then intrducing foods one by one, and seeing reactions.
Each new food is tested for 2 weeks.
