Clinical Endocrinology Laboratory

The Clinical Endocrinology Laboratoryis a non-profit, self-funded service unit, within the Department of Population Health and Reproduction that proudly serves veterinarians, owners and others managing all manner of species from a variety of local, national and international institutions including universities, zoos, research laboratories and private practice. The lab continues a long and distinguished history of developing, running and interpreting hormonal assays, in particular reproductive hormones, for pregnancy and disease in males and females.






We now offer mass spectrometry measurement of progesterone/DHP ratios for determination of placental support of pregnancy, and as evidence for the safe removal of pregnant mares from progesterone supplementation. Please see complete information and submission form.

Feline/Canine anti-Mullerian hormone  (Spaychek/AMH) testing is currently available. Testing with Spaychek from Preventia Diagnostics is a safe, humane and cost effective alternative to surgical exploration to determine spay status . Please see more information under anti-Mullerian Homone Testing. The test may be submitted using our sample submission form.
