EIA Mobile App is now available!
- Go to your App Store or Play Store and search for "USALIMS-A". Once downloaded call the lab to request a username and password. Please note: This app is currently only for submitting equine serum samples to AHL for EIA testing. If using another laboratory for your EIA testing needs call that laboratory to inquire about obtaining a username and password from them directly for the EIA mobile app.
2021 - 2022 Trich Tags
- Trich tag color for October 1, 2021 to September 30, 2022 is WHITE. Any white tags you have purchased in previous years can be used now. Call (303) 869-9230 now to get your trich tags and tubes ($7.50/tube) ordered.
The lab moved April 2019 to Broomfield!
- Important notices about Trich testing
- AHL offers Pooled Trich Testing. The cost is $35.00 per pool of 5 samples. You will still need to collect the individual samples in InPouches or Trich Transit Tubes as pooling is conducted only in the laboratory. Please note, if any of the pooled samples are found to be positive, PCR will be done on each sample in the pool at a cost of $25.00 per sample.
- If using Pooled PCR and traveling out of state, please make sure the state to which the bulls are traveling to accepts Pooled Trich PCR sample results.
- Any Trich InPouch or Trich Transit Tube samples requesting PCR or Pooled PCR testing must be received within 72 hours of collection.
- Although AHL advises against using Lactated Ringers (LRS), if used, the sample must be received within 24 hours of collection and will be transferred to either an InPouch or Transit Tube (depending on requested test) upon arrival, and the submitting veterinarian will be charged the cost of the media as well as a transfer fee. EXPIRED POUCHES AND TUBES WILL NOT BE ACCEPTED.
- 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.
- Disease Information and Brochures
Below are some resource materials for just a few of the diseases tested at the Rocky Mountain Regional Animal Health Laboratory. Each of the brochures are available for download in a PDF format.
Bovine Leukosis Virus (BLV)
Bovine leukosis virus is a retrovirus infection of dairy and beef cattle. The virus survives in white blood cells, called lymphocytes. Only about 5% of the cows infected with this blood-borne disease ever develop a clinical disease. If clinical disease is not present, BLV infection may be diagnosed by blood tests (AGID and ELISA) that detect the presence of BLV antibodies. BLV infection does not occur naturally in other species. BLV infection is for life; once an animal is infected, it is virus positive for life.
Caprine Arthritis Encephalitis Virus (CAEV)
Caprine Arthritis Encephalitis Virus is a disease of goats. Those infected with CAEV may develop arthritis, mastitis, encephalitis, and/or pneumonia. The primary route of transmission is through ingestion of virus-infected colostrum or milk by kids. Contact with the blood of an infected animal can also transmit the disease. Currently there is no vaccine available for CAEV.
Johne's (Mycobacterium avium subsp. paratuberculosis) Disease
Johne's Disease is a chronic intestinal disorder primarily of ruminants. Symptoms include decreased milk productivity, diarrhea and weight loss despite a good appetite. A recent survey of Colorado dairy cattle found a 4% seroprevalance of Johne's Disease among cattle at least 2 years of age (JAVMA 2004 Jul 1, 225(1): 97-101).
Scrapie is a fatal nervous system disease of sheep and goats and is caused by the same family of infectious agents as Mad Cow Disease. Scrapie is a major concern to the sheep and goat industry, causing significant production losses. Moreover, the presence of scrapie in the United States also limits the export of breeding stock, semen, and embryos.
Trichomoniasis is a venereal disease of cattle caused by the protozoan parasite Trichomonas foetus. Bovine trichomoniasis is spread by breeding and causes infertility, abortions, and occasionally chronic uterine infection in dairy and beef cattle. Losses include reduced milk production, reduced calf crop, and delayed breeding. Diagnosis of the disease requires demonstration of the organism in the tissue or most frequently in culture. There is not a treatment for Bovine trichomoniasis.
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. Please let us know in advance if you have a large order to place so that we may have the full quantity of the item you need.
Orders need to be placed by 1:00 pm to be sent out same day.
AHL also supplies Tuberculin, EIA Test Records, Brucellosis Test Records and more! Call us to find out more information.
Testing Services and Fees
When sending samples via FedEx, UPS or USPS please package samples carefully so they are not damaged in transit. Submissions to the laboratory should comply with applicable biosafety regulations. Submissions to the laboratory must be accompanied by a proper submission form for all samples except EIA mobile submissions.
Testing charges will be billed to the veterinarian submitting the samples. There is no additional charge for samples originating from out-of-state.
A sample submission form, VS 10-11 or VS 4-33 must accompany all samples tested at the Animal Health Laboratory (unless using the LIMS portal or EIA Mobile App). The chart must contain the following information.
- Veterinarian's Name
- Date sample was taken
- Owners Name
- Physical Address of Animals
- Type of test to be run
- Recorded tube numbers of the animals being tested that has been matched up to the sample taken
Any information missing can lead to a delay in your test results being finished. Please take the time to check all required information is on the submission form before mailing samples in.
The Animal Health Lab offers a general sample submission form that is to be used for general serology for Anaplasmosis, Bluetongue, Bovine Leukosis, Brucella canis, Brucella ovis, Caprine Arthritis Encephalitis, Johne's Disease, Pseudorabies, and Tritrichomonas foetus. A VS 10-11 form (unless using the EIA Mobile App) must accompany EIA samples and a VS 4-33 must accompany all official Brucella abortus, Brucella suis and Brucella melitensis testing.
USDA Forms are now available at AHL, give us a call at 303-869-9230

- Q: What kind of tube can I use?
A: For most of the serological testing done here, any red top or serum separator tube, 10 cc or less is acceptable.
If you are submitting for Scrapie Genetic Susceptibility testing only whole blood purple top tubes with EDTA are acceptable.
- Q: How long can I expect to wait for results?
A: See Testing Services and Fees for testing turn-around-times.
Questions Regarding Public Health Issues
- Q: What do I do if I've found a dead squirrel or bird?
