The new IDEXX/EBI® EHV-1 RealPCR Test™ helps you confidently:
- Diagnose horses exhibiting clinical signs consistent with EHV-1 disease
- Diagnose horses exposed to confirmed EHV-1 cases
- Isolate infected or exposed horses from other susceptible horses in a timely manner
- Identify EHV-1 strains containing a mutation that is highly associated with neurologic
clinical signs
Equine Herpesvirus Type 4
Equine herpesvirus type 4 (EHV-4; equine rhinopneumonitis virus) is a health risk to equine populations worldwide. Disease severity depends on multiple factors and may be latent in normal horses. And because clinical signs are similar to other respiratory diseases, it is difficult to make a definitive diagnosis from clinical presentation alone.
The IDEXX EHV-4 RealPCR™ Test identifies:
- EHV-4 in horses presenting with respiratory clinical signs
- Horses that have been exposed to confirmed EHV-4 cases
PCR methods help distinguish between EHV-4, EHV-1 and EHV-1 neuropathogenic strains
Horses presenting with respiratory disease may have a dual infection with both EHV-1 and EHV-4. With the EHV-4 and EHV-1 RealPCR™ Tests, an equine practitioner can quickly distinguish between EHV-4, EHV-1, and the EHV-1 neuropathogenic mutant strain, to manage disease and prevent the spread of the virus to other horses.
The EHV-1 and EHV-4 RealPCR Tests are performed daily,
Monday–Saturday.
- Results are available within 24 hours.
- Results for specimens received on Saturday are available the following Monday.

Sample collection guidelines: recommended specimens
are whole blood and/or nasal swabs from both nostrils.*
- Whole blood: at least 7 mL in a 10 mL purple-top tube.
- Nasal swabs: Dacron swabs moistened with <0.5 mL Ringer’s solution/ buffered saline (not water) in an empty sterile red-top tube. Do not use swabs with wooden shafts or cotton ends.
- Ship within 24 hours of collection. If necessary, store at
4°C, but do not freeze.

 *Nasal swabs are used to detect animals shedding the virus or that were recently exposed to a confirmed case. A whole blood sample is recommended from a symptomatic animal to detect viremia. Submission of both sample types is ideal. Each sample will be considered as a separate submission.
