PCR samples that showed no evidence of BVD within the analytical range (maximum 40 Ct) are not reported with a specific Ct value, but rather are labeled undetected.
In the event of a positive group/pool, ELISA testing may have been done along with PCR testing to assist in identification of specific positive animals within a test positive pooled sample. If both pooled PCR and ELISA results are listed for a specific animal within a submission, refer to the individual animal sample (ELISA test) as the final result.
