Additional Information

For pooling, samples must be collected, identified and submitted individually. The laboratory will pool up to five samples per pool. If pooled sample yields a positive result, samples in that pool will be tested individually upon request for an additional charge.
Due to supply issues with one of the extraction kits, Johne’s PCR testing will be reduced to Wednesday and Friday until further notice.
