Single ear notch (1cm/side). Do not send large pieces of ear tissue.
Collect ear notch (1cm/side) from each animal and place in a dry, sterile tube (e.g. 6 ml with push up plastic cap preferred, serum tube-no separator gel or anticoagulant). Individual samples must be identified and submitted separately; samples will be pooled by the laboratory. Up to 24 ear notches/pool.
Disinfect tools with 10% bleach (e.g., 100ml (3oz) bleach in 900ml (27oz) water) or 1% Virkon, between animals; rinse thoroughly with water. Specimens MUST be free of dirt, feces, tattoo ink and vaccine. Residual disinfectant or contamination with feces or tattoo ink can yield false negative results. Do not vaccinate while collecting ear notches - this can lead to contamination with extraneous BVDV, causing false positive results.
A medium ear notch tool works well (e.g., Nasco: 800-558-9595, size-Medium C0024N, or Valley Vet Supply: 800-419-9524, size-Medium 17016, or similar tool that cuts a notch that is ½” wide at base).
Keep refrigerated for a maximum of 72 hours. If unable to ship to arrive at the lab within 72 hours, freeze and ship the next business day Mon-Thur only.
Not for testing animals exhibiting clinical signs - please refer to individual BVDV-PCR test information.
*Fee is $65.00/pool. Individual specimens within a positive pool will be identified by BVDV ELISA for an additional fee of $4.00/ear notch.
Samples from different owners will not be pooled.
Pooled testing should only be used for detection of Persistently Infected (PI) animals in herds without clinical signs of BVDV. Although it is possible to detect acute BVDV infections, clinical suspects should be tested individually to avoid false negative results. If an animal tests positive, we recommend testing again in 3-4 weeks to confirm PI status. EDTA blood is the preferred specimen for follow-up testing.
USDA approved test.
