  Comments Samples will be tested using a Canadian ELISA kit that is not licensed for use in the US by the USDA. Bovine leukemia virus (BLV) infection is life-long in cattle, therefore POSITIVE antibody result indicates BLV persistent infection. However, testing of animals less than 6 months of age by serological tests could lead to a false positive result due to passively acquired maternal antibodies. If an USDA-Licensed test is required for sale or export/import, please contact the Laboratory for appropriate test.
