6.2 Serum neutralisation test |
The serum neutralisation test (SNT) is accepted as the „gold standard“ for BVD antibody detection. It is suitable for the detection and quantification of BVD-specific antibodies in serum. Depending on the test setup, it provides information on recent infections, infective status of a herd or the efficiency of a vaccination program (for a determination of the viral incidence in a herd only one serum sample is necessary, whereas an acute infection has to be tested with a paired serum sample 2-3 weeks apart, whereby a fourfold increase in the titre is considered to be significant).
