| Fee | $58 |
| Days Tested | Tue |
| Turnaround Time |
2-15 days, depending on results, number of samples submitted, and time of year. Improperly labeled cases (i.e. those with only animal IDs on specimens), may be placed at the back of the queue and take up to 4 weeks for testing. |

| Specimen | Feces (2 gram minimum) in plastic, leakproof, screwcap containers. |
| Sampling Requirements | |
| Collection Container | Samples must be submitted in plastic, leakproof, screwcap conatiners. |
| Packaging Instructions | Samples MUST be labeled with the sample number (1, 2, 3, etc.) that corresponds with the identification form. |
| Additional Information |
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 will be at the current individual rate per sample tested. See our 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. |
