Equine Chemistry Testing
In addition to a complete range of routine tests, our innovative tests include:
- SDH (sorbitol dehydrogenase)—a highly specific liver enzyme that is a sensitive indicator of liver disease (hepatocellular leakage)
- Endocrine testing, such as endogenous ACTH, insulin and dexamethasone suppression tests
- Bile acids so you can evaluate liver function

Equine Hematology Testing
IDEXX offers a comprehensive equine CBC, which automatically includes fibrinogen estimates (by heat precipitation) and plasma protein, and manual slide review on all abnormals for a more complete picture. Manual slide review could reveal:
- Toxic change: an indicator of response to inflammation
- Left shift: release of immature neutrophils in response to inflammation
- Hemaparasites: e.g., Ehrlichia equi (Anaplasma phagocytophilum), Babesia and other parasites
- Atypical cells: e.g., leukemia fibrinogen is always automatically included in the equine CBC for indicating inflammation

Equine Serology and Microbiology Testing
- Coggins testing by AGID and ELISA procedures
- A complete line of infectious disease serologic testing, including leptospirosis, Lyme disease and other tick-borne disease
- IgG testing for foals to indicate adequacy of passive transfer
- Automated microbiology system to allow more rapid culture results with minimum inhibitory concentrations (MICs) to improve selection of antibiotics
