Samples are pooled at the laboratory in pools of up to 5 samples. Pooled testing can only be performed on fecal samples. Indicate whether the samples should be pooled or tested individually, otherwise submissions containing greater than 5 samples will be pooled. Retest of positive pools is $25.00 per individual sample (5 individuals per pool X $25 = $125 per retested pool). See submission guide for sample collection and submission guidelines.
Results of pool cases may take up to 15 days, dependent on retesting of pools and time of year. Individual samples requested on pool cases will not be reported out before the pool retests are finalized.
The NDSU-VDL is an APHIS-approved laboratory to conduct official Johne’s testing. Approval is based on satisfactory annual proficiency test scores.
