What It Is

What It Is

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. PSPB is a protein that is produced only by the placenta of the growing fetus. Blood can be drawn on cows and heifers at 28 days or more post-breeding and cows must be 73 days post-calving to ensure accuracy. If a sample is taken within this 73 day postpartum window, there is a chance for a false positive due to residual PSPB which has not cleared from the maternal blood stream.
