BioPRYN Blood Pregnancy Testing

What is BioPRYN


BioPRYN® is a pregnancy detection tool for use in ruminant animals. It measures the presence of Pregnancy-Specific Protein B (PSPB) in the blood circulation of the animal. The PSPB is a protein that is only produced by the placenta of the growing fetus. Cows and heifers must be 30 days post-breeding and cows - 90 days post-calving. There is a chance for a false positive if the residual PSPB has not cleared the maternal system from cows that have calved more recently than 90 days ago.




How It Works
BioPRYN® begins with collection of a blood sample 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 dairy management software or sent via email or fax.
Using BioPRYN assures accuracy. The test is 99 percent accurate in identifying open females, giving producers confidence to administer a prostaglandin shot and restart a synchronization program. There is as much as a 5 percent false-pregnancy rate from the test, primarily due to early embryonic death which is a challenge regardless of which method is used for pregnancy detection.
