Featured Tests

IDEXX SDMA® testing

Earlier intervention for more effective management of kidney disease

SDMA, symmetric dimethylarginine, is produced in every cell and released into the body’s circulation during protein degradation. SDMA is excreted by the kidneys, making it a good marker for estimating kidney function. Identifying kidney disease earlier could help manage a horse's kidney disease more effectively.

Equine Diarrhoea RealPCR Panel

Faster, more definitive diagnoses of equine gastrointestinal diseases

Identifying the pathogens causing equine gastrointestinal disease is critical for determining treatments, implementing biosecurity protocols and managing the spread of disease. Treatment protocols can be costly and inconvenient, so a quick, accurate diagnosis is essential.  

With the IDEXX Equine Diarrhoea RealPCR Panel, veterinarians can now submit one sample to test for either 6 or 10 gastrointestinal pathogens.

The Equine Diarrhoea RealPCR Panel is available in two configurations: Comprehensive and Standard. If a positive Salmonella PCR result is obtained with either panel, a culture and sensitivity test will be performed.

  • Optional add-on test: Equine Arteritis Virus RealPCR Test (must be selected on test requisition form)
Specimen requirements

Deep nasopharyngeal swabs (one from each nostril). Please submit dry, plastic-stemmed swabs, without transport media, in a sterile tube; keep refrigerated. Collect specimen prior to antibiotic administration.

Turnaround time

1–4 working days for RealPCR panel; allow additional time for culture

Equine Herpesvirus Types 1 (EHV-1) and 4 (EHV-4) RealPCR™ Tests

New weapons in the fight against infectious diseases

Equine Herpesvirus Types 1 (EHV-1) and 4 (EHV-4) RealPCR Tests are sensitive tests that use real-time PCR technology to deliver speed and accuracy in detecting the presence of EHV-1 and EHV-4 DNA.

Equine Herpesvirus Type 1

Numerous outbreaks of EHV-1 have hit the equine industry, resulting in great loss.

EHV-1, a virus often found latent in normal horses, can present as respiratory disease or neurologic disease, or cause abortions. Once in a population of horses, the virus is spread quickly and can cause devastating results.

The Equine Herpesvirus Type 1 (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. Because clinical signs are similar to other respiratory diseases, it is difficult to make a definitive diagnosis from clinical presentation alone.

The Equine Herpesvirus Type 4 (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.


Specimen requirements

2 mL EDTA whole blood and/or deep nasopharyngeal swabs (one from each nostril). Please submit dry, plastic-stemmed swabs, without transport media, in a sterile tube; keep refrigerated.

Note: Nasal swabs are used to detect animals shedding the virus or that were recently exposed to a confirmed case. A whole blood specimen is recommended from symptomatic animals to detect viremia.

With IDEXX RealPCR tests, you can count on
  • The latest innovation in PCR technology, with the virtual elimination of false positives.
  • Fast answers, so you can work through your list of differential diagnoses faster.

Equine Faecal Egg Count Panel

When evaluating the effectiveness of a deworming program, simply determining the presence or absence of eggs is not enough.

The IDEXX Equine Faecal Egg Count Panel provides a quantitative analysis of egg count, so you can accurately monitor anthelmintic performance and recommend adjustments as necessary.
Consider running the IDEXX Equine Faecal Egg Count Panel when:

  • Determining the worm burden within an individual horse or on a farm
  • Evaluating anthelmintic efficacy

Additionally, this test will give you the information you need to help clients understand if their current deworming programs are working—and where you can make recommendations to improve effectiveness.

IDEXX Rhodococcus equi RealPCR™ Test

The IDEXX Rhodococcus equi (R. equi) RealPCR™ Test:

  • Detects strains that contain the virulence plasmid (VapA gene)
  • Includes culture confirmation of the presence of R. equi bacteria, virulent or avirulent strains

PCR methods are more rapid and sensitive than culture, and can identify virulent R. equi

Horses are unique in that the R. equi strains which cause disease almost all contain a plasmid that carries a virulence gene. VapA, whose function is not well understood, is necessary for clinical disease.

The detection of R. equi by standard bacterial culture can be difficult if the horse has received antibiotic therapy. Further, culture cannot identify strains that carry the virulence plasmid. PCR methods are not only more rapid and sensitive than culture, but also can identify virulent R. equi.

Sample requirements
  • Recommended specimen is at least 5 mL of tracheal wash fluid placed in a sterile tube without preservatives.
  • Ship with ice pack within 24 hours of collection if possible. If stored, refrigerate at 4°C but do not freeze.
Turnaround times

Test is performed daily, Monday–Friday, with results available within 48 hours.

IDEXX Streptococcus equi (S. equi) subsp. equi ELISA

Quantify Streptococcus equi subsp. equi antibody levels using the test that measures the immune reponse to the SeM protein, the major virulence factor of S. equi subsp. equi.

Performed on serum, this test provides antibody levels as titres in one of five different categories:
  • Negative
  • Weak positive
  • Moderate positive
  • High positive
  • Very high positive
This test is very useful if you suspect:
  • Recent infections or recent vaccinations
  • The need for booster vaccinations
  • Purpura hemorrhagica
  • Metastatic abscesses (“bastard strangles”)
  • Streptococcal myositis
Sample requirements

1 mL of serum.

Turnaround time

Results are available in 14 working days.
