- Important notices about Trich testing
- Individual and Pooled RT-PCR testing available. If testing bulls to move out of state, please make sure the state to which the bulls are traveling accepts RT-PCR (individual and/or pooled testing) results.
- The cost is $40 per pool of 5 samples, or $8 per sample in the pool, with a minimum charge of $24 per pool (for 2 or 3 samples in a pool). You will still need to collect the individual samples in acceptable media as pooling is only conducted in the laboratory. Please note, if any of the pooled samples are found to be positive, individual RT-PCR will be done on each sample in the pool at a cost of $30 per sample.
- The lab accepts preputial scrapings in BioMed InPouch and TF Transit Tubes, Diamond's media, phosphate-buffered saline (PBS), and sterile saline up to 144 hours (6 days) after collection. Please continue to ship the samples to the lab as soon as possible after collection to allow for shipping issues and delays. If necessary, refrigerate samples until shipment.
- Please continue to legibly label tubes with veterinarian, owner name, and bull identification numbers and complete a sample submission form with the Trich tag ID (if bulls are staying in state) and official ID (i.e. 840 or 84 tag) and the type of media the sample was collected in.
- Need media? We are selling PBS tubes for $20 per pack of 10 tubes. Want to use your own? Please use at least 3 mL of PBS or saline (please do not use tubes larger than 10 mL, do not have any additives, and ensure they are leak-proof).
- Once samples are received in the laboratory, they become the property of the laboratory and will not be returned to the client for any reason.
Supplies are available from the Colorado Department of Agriculture Animal Health Laboratory to accredited veterinarians. Some quantities may be limited and all prices are subject to change.
