Animal Health

BVDV demands a confident response

Bovine viral diarrhea virus (BVDV) suppresses a cow's immune system, making the animal susceptible to a host of other infections. That's why BVDV is one of the world's most costly bovine diseases for both dairy and beef producers, with losses of $15–$88 (£10–£60)1 per head from reduced herd productivity, health and reproductive efficiency.

Stopping BVDV requires detecting and removing the infection source: persistently infected (PI) cattle that continually expose other animals to disease.

Because PI cattle often look healthy, a sensitive, specific diagnostic test is essential. Mistakes can be costly: whether it’s removing a valuable animal from production or allowing an infected calf to join the herd.


The IDEXX BVDV Ag/Serum Plus Test Accurately Targets BVDV PI Cattle

The IDEXX BVDV Ag/Serum Plus Test is the only test based on the BVDV Erns antigen, a protein abundant in the blood and tissue of BVDV PI animals and stable under a wide range of environmental conditions.

Erns detection makes the IDEXX test robust, reliable and accurate.


  • Detects BVDV infection in old or poor quality samples; no special sample handling required
  • Appropriate for any cattle operation—dairy or beef


  • Works with blood, serum, plasma and ear-notch tissue; allows veterinarians to request BVDV tests on samples collected for other tests
  • Tissue samples show no interference with maternal antibodies; can be used even with newborns


  • Detects BVDV genotypes 1 and 2 and all known field strains
  • Demonstrates specificity >99.7% and sensitivity approaching 100% in tested populations


Familiar ELISA Format Fits Easily into Any Laboratory

  • Requires no additional investment in training or equipment
  • Supports manual, semiautomated or fully automated work flows for higher throughput and increased revenue
  • Short and long protocols adapt to your laboratory’s schedule


Reliable Results Inspire Confident Decisions

Results from the IDEXX BVDV Ag/Serum Plus Test help producers make the
right decisions to protect their herds from BVDV.
