About

The qPCR test detects the genome (DNA) of Equine Herpesvirus Type 4 (EHV-4).

Molecular detection by qPCR is the most sensitive, specific and accurate method for assessing the infectivity of affected horses.

What is Equine Herpesvirus Type 4 (EHV-4)?

Equine Herpesvirus Type 4 (EHV-4) is distributed worldwide and is an important cause of respiratory disease in horses.

Clinical signs often overlap with those of other respiratory infections, making laboratory testing essential for an accurate diagnosis.

Why test?

The qPCR test provides rapid and accurate detection of Equine Herpesvirus Type 4 (EHV-4) and supports the diagnosis of respiratory disease associated with EHV-4 infection.

Clinical signs

Infection is primarily restricted to the respiratory tract and associated lymph nodes.
Respiratory disease is the main clinical presentation.
Abortion in pregnant mares is uncommon with EHV-4 strains.
Most infected horses establish latent infection, with viral shedding potentially reactivating during periods of stress.

Transmission

Transmission occurs through:

Aerosolised respiratory secretions from coughing horses.
Direct horse-to-horse contact.
Indirect contact via contaminated equipment or objects (fomites).
Nasal secretions from clinically healthy carrier horses.

The air and environment surrounding infected horses may also become contaminated with the virus.

Prevention

As latent carrier horses are common, eradication from a herd is extremely difficult.

Preventive measures include:

Routine vaccination to increase herd immunity.
Good herd management practices.
Keeping horses in small, closed groups whenever possible.
Minimising stress to reduce viral reactivation.
During outbreaks:
Isolate affected horses.
Disinfect contaminated facilities and equipment.
Implement strict biosecurity protocols.

Results

FAQs

Who collects the sample? Your veterinarian. See Sample for the material and the volume this test requires.

How should the sample be sent? Keep it cool and send it by tracked courier as soon as it is collected. Shipping is arranged and paid for by the client.

What happens if the sample arrives unsuitable? We contact you before processing and ask for a new sample.

Can other tests be added to the same sample? Often yes, if the material and the volume allow it. Ask us before shipping.

How long does it take? See Turnaround. The count starts when the sample arrives at the laboratory, not when you order.
