General information about the disease:

Bovine viral diarrhoea virus (“pestivirus”) is one of the most significant viral diseases in cattle.  A range of tests are available to investigate disease in various ages and classes of cattle.

General information about when this test is indicated:

If cattle are suspected as having been infected with BVD virus, a VNT can be used on paired convalescent sera.  This is a more expensive test than other BVD testing options and not used as frequently now the BVD antibody ELISA has been validated as a quantitative test.

Comparison with other related tests: Can be used in conjunction with BVD antibody ELISA, PCR and antigen ELISA testing.

NOTE – This test is not performed by Awanui Veterinary and requires referral to an external reference laboratory.
