Equine Diagnostic Plans and Panels

Updated July 28, 2021

The following diagnostic plans have been developed primarily as an educational tool to assist the veterinarian in designing a complete, although not exhaustive, diagnostic strategy. To encourage veterinarians to select only the tests that are deemed clinically appropriate in each situation, the price of the diagnostic plan is not discounted from the sum of the individual test costs.

For the test groupings labeled as panels, there may be a discounted price versus the costs of the individual tests. Diagnostic plans and panels can be requested by writing the complete name as the test request. If appropriate samples are included all tests will be performed.

Antimicrobial susceptibilities for culture isolates are available upon request at an additional charge.

To avoid testing acute samples twice, hold and submit with convalescent samples. If convalescent samples will not be collected, or when infectious abortion is strongly suspected due to history, immediate testing of acute sample may be warranted.

Notes

For fever in a foal, please refer to Equine Diarrhea/Septicemia, Neonatal Foal Acute Diarrhea Diagnostic Plan.

This diagnostic plan is designed to detect a broad spectrum of systemic bacterial, viral, and some blood parasite causes of acute fever of unknown origin, as well as certain inflammatory changes which may assist in determining the underlying problems. Viral causes of illness are best detected during the first week of illness. This plan is not intended to be ordered in its entirety, rather the clinician should select the most appropriate tests consistent with the patient’s history, clinical signs, geographic location and season. See Large Animal Internal Medicine, 6th Edition, 2019, Chapter 4: Fever of Unknown Origin

Please note that additional referral diagnostics to consider with this plan may include Caseous lymphadenitis, Encephalitis, Eastern, IgM ELISA, Lawsonia IPMA and Piroplasmosis c-ELISA. These referral diagnostics must be sent directly to their respective diagnostic testing laboratory for out of state submissions and those cases that are not under NY state contract. Visit our referral testing web page for referral lab contact information. Please contact the AHDC Veterinary Support Services team with any questions (vetsupport@cornell.edu, 607.253.3900).

Please note that additional referral diagnostics to consider with this plan may include Polysaccharide Storage, Lawsonia IPMA, HYPP, Muscle Profile, Immune Mediated Myositis (MYHM Mutation) and Streptococcus equi ELISA. These referral diagnostics must be sent directly to their respective diagnostic testing laboratory for out of state submissions and those cases that are not under NY state contract.

Notes

May want to retain feed sources including hay for possible botulism testing. Contact lab for more information.

For an increase in sensitivity in diagnosing EHV-1 include a nasal swab in a red top with 0.5 ml sterile saline and request Equine Herpes Virus-1 (EHV-1) PCR for an additional charge.

Please note that additional referral diagnostics to consider with this plan may include EPM SAG Titer ELISA. Referral diagnostics must be sent directly to their respective diagnostic testing laboratory. Visit our referral testing web page for referral lab contact information. Please contact the AHDC Veterinary Support Services team with any questions (vetsupport@cornell.edu, 607.253.3900).

Note that EEE is not reliably detected in whole blood (CSF and brain tissue are more appropriate samples), however, EEE PCR is warranted on whole blood samples if the season and clinical signs are compatible and other samples are not available.

The Eastern Encephalitis IgM ELISA must be run in conjunction with EEE PCR to increase diagnosis of this viral disease. The course of the disease may cause a change in the results of the PCR and IgM; therefore, it is necessary to run both tests together to increase the diagnosis of EEE.

Notes

When acute and convalescent samples are/will be collected, for most serology assays they should always be tested in parallel, and paired results interpreted. If acute samples are submitted alone please indicated if all tests should be performed. If second, convalescent samples are later submitted, tests on both samples will be run in parallel and fees for both samples will be charged. To avoid testing acute samples twice, hold and submit with convalescent samples. If convalescent samples will not be collected, or when infectious abortion is strongly suspected due to history, immediate testing of acute sample may be warranted.
