Positive: Excellence

Excellent diagnostic tests and EXCELLENT customer service! I switched to Pet Preferred Dx after talking to Khris - and he explained all the science. I compared the results from his lab to Greer, and Pet Preferred Dx seem to be significantly more accurate. The food allergy and food intolerance test, have proven over and over to be highly accurate - my clients end up seeing me less, and trusting me more! The new cancer test is helpful for the owner that is always worrying about their fur babies. I have used the cancer test to support my theory of cancer and as a screen of healthy patients. Khris is ALWAYS available to talk to me and explain results to me. I can honestly say, they have NEVER disappointed me!
