How to prepare for using bioPRYN®

The herd owner or vet follows these simple tasks:
-Makes a list of all eligible animals
-Assembles Vacuatiner® tubes (red or gray and red topped), needle holders, and needles (1 inch, 18 or 20 gauge) from a vet supplier.
-Samples at least 2 cc (5 cc for wildlife) of blood
-Avoids cross contamination by using new supplies for each animal.
-Labels each tube using water-insoluble ink or pencil with the tube sequence # and the animal #.

Tube Labeling Instructions:

-Packages samples for delivery to the laboratory
-Encloses a Sample Submittal Form with the sample and tube sequence numbers and list and fills in the blanks on the form.
The sample submittal form indicates how tests results are to be delivered (mail, fax, phone, e-mail).

About Us: The Schwertner family has been involved in the livestock dealer business for over 63 years. Teresa Schwertner is the fourth generation 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 herd, so Teresa Schwertner opened Bio Preg Check, LLC in April 2008 in Wharton, Texas. Teresa, who has been involved in the auction business for 30 years, is the owner and operates the laboratory. She handles the technician duties, marketing, and the day-to-day operations of the business. Dr. Tom Gary is the DVM on staff and Billy Schwertner and Bernard Lee handle the public relations.

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 we expect it to continue to increase this year. The BioPRYN® test is growing rapidly in the beef cattle business in the southern states. Teresa says the 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.
