About Us

Your reproductive speacialists

Our History

In April 2006, Precision Diagnostics LLC began offering the BioPRYN blood-based pregnancy test as an affiliate of Biotracking LLC. That first year we tested 9,082 dairy and beef samples. Since that time we have introduced the sheep and goat BioPRYN test for pregnancy as well as the CAE ELISA. As we gained the confidence of livestock producers, we experienced steady growth each year and, in 2016, we processed 95,190 total samples from 27 different states.


In addition to lab services, our artificial insemination and embryo placement training programs have brought a new level of excellence to the livestock industry. Also, since 2010, we are the exclusive distributors for Global Ag Alliance, a provider of high conception bovine semen. As our byline states, we really are specialists in reproductive management.
