Comprehensive laboratory testing including innovative, exclusive diagnostics.

The best menu of industry-leading diagnostics

IDEXX Reference Laboratories offers specialized equine testing and offers expertise in detecting the serious diseases affecting horses today.

Along with providing a team of board-certified equine specialists and the latest advancements in equine diagnostic research, IDEXX offers innovative new tests and delivers accurate, comprehensive results up front, so you can make more informed and confident medical decisions.


The nationwide network of IDEXX Reference Laboratories offers the following equine testing options:

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
