Proven, accurate, convenient, cost-effective.
BioPRYN® is the first and leading protein-based blood pregnancy test that delivers fast, accurate, and economical pregnancy test results from a simple blood sample. Applications of this technology have been documented in scientific and veterinary based publications since 1982.1, 2
The BioPRYN enzyme-linked immunosorbent assay (ELISA) test evaluates the serum or plasma of all dairy breeds for a protein called Pregnancy Specific Protein B (PSPB). PSPB is produced by the placenta of an animal with a growing fetus and remains until after parturition. PSPB concentrations can be accurately measured in blood by 28 days post breeding (DPB) in adult beef and dairy cows and 25 DPB in beef and dairy heifers.
