I've had a great experience working with Pet Preferred diagnostics! The short turn around time for their allergy panels really helps on the diagnostic aspect of managing my allergy patients. Dr. Khristofor is also always willing to discuss the results and provide his professional insight in developing a treatment protocol. Excellent service!
