About Us
Our turnaround time for delivering results once samples are received is two weeks. Our lab will provide you with detailed results specific to the tests requested. Clients must send pulled hair samples with at least 30 to 60 hair follicles attached. We also accept blood and semen samples. However, please contact Lab Director Dr. Rytis Juras before sending samples other than hair.
We provide several services for horses, donkeys, and cattle including individual genotyping, parentage, and coat color testing. Learn more about which tests we offer for which species.
We offer ancestry testing for horses, which requires samples of 30 to 60 hairs with intact follicles. We then provide a horse genotyping report and an ancestral equine report.
Our lab focuses on studying the heredity basis of equine congenital defects and economically significant traits in domestic animals (mainly the horse) and other genetic and genomic concepts.
Frequently Asked Questions (FAQs)
Please allow up to two weeks for the samples to be completely processed once we have received them. Sometimes, our lab does not receive mail until a much later date than when a sample was sent. Usually due to the mail getting lost along the way. Other times, the sample received is not of the best quality, so multiple tests need to be performed.
The billing process has multiple steps, it often takes accounting a while to process our checks. The best thing to do is keep checking your check status, if it has not been cashed within a month, please contact us.
We accept hair, blood, and semen. Please ensure that samples are properly packaged and shipped.
There is no way to determine the exact accuracy of our test, we use a computer system that runs the individual horse against a panel of 50 breeds. We then calculate the probability that the subject horse falls into the breeds and report on the top three highest probabilities. For further reading, please see Horse Ancestry page.
All we ask if that you fill out what you know. If there is any information you don’t know or can’t find, you can leave it blank.
Please refer to the “Interpret Reports” section on our Forms page. If you have further questions, you can contact us.
A good hair sample is pulled, NOT cut. You need to make sure there are decent bulbs (hair follicles) so that we can extract the DNA. If you are unsure how to get a good sample, you can refer to these videos and many others found online. Here are some pictures of good DNA hair samples.
