What is Bio Preg Check?
Bio Preg Check uses and markets the BioPRYN blood pregnancy test for cattle.

BioPRYN® (Pregnancy Ruminant Yes/No) is a pregnancy detection procedure in cattle. It measures the presence of Pregnancy-Specific Protein B (PSPB) in the blood circulation of the animal. The PSPB is a protein that is produced by the placenta of the growing fetus. BioPRYN® begins with collection of a blood sample (2cc) from the animal. The samples are then shipped to a laboratory where an enzyme-linked immunosorbent assay (ELISA) is performed. Reports may be downloaded directly into ranch management software. Using BioPRYN® assures accuracy. When the livestock producer or veterinarian draws blood samples from the animal(s) at the correct time (28 days post natural breeding, 28 days after AI, and 34 days of embryo life in the case of embryo transfer) after breeding and 72 days after calving in cattle, the pregnancy question is answered within 27 hours after testing begins!

About Us:
The Schwertner family has been involved in the livestock dealer business for over 63 years. Bio Preg Check was founded by Teresa Schwertner, a fourth generation family member involved in the cattle auction barn business. H.W. (Billy) Schwertner, auction proprietor and rancher first started using BioPRYN®, the blood-based pregnancy test in his own cattle in January 2007. The test worked well on their breeding herd, so Teresa opened Bio Preg Check, LLC in April 2008 in Wharton, Texas. Teresa owned and operated Bio Preg Check until her passing in May 2019. The Schwertner family will continue to operate Bio Preg Check along with the dedicated team of staff and lab operators. 

In the first nine months of the laboratory, a total of 15,204 samples were assayed. In 2009, the pregnancy checks handled in the lab has grown by 30 percent, and has continued to increase each year. The BioPRYN® test is growing rapidly in the beef cattle business in the southern states. BioPRYN® test is working great for the large beef cattle producers, but also fits the small urban rancher. Some of the factors for the success is the ease of the blood collection process, the accuracy of the test, and its affordability.
