AHDC Veterinary Support Services (VSS) veterinarians will answer diagnostic consultation and sample submission questions from veterinarians outside of regular hours. To reach VSS Veterinarians use this direct email,, with a very brief problem description in your email and a DIRECT phone number to reach you. If very urgent, note URGENT in the subject line. We will do our best to respond by phone or email as quickly as possible.

Referral testing that the AHDC normally sends out to other laboratories for our clients is being temporarily suspended due to the rapidly changing status of diagnostic laboratories across the country. These tests have been temporarily removed from our catalog and will no longer be available through the AHDC until further notice. Please contact our Veterinary Support Services team at or call 607.253.3900 if you need assistance on the availability of testing services at other laboratories.
