What is BioPRYN® and how does testing work?
​
BioPRYN® accurately measures the presence of Pregnancy Specific Protein B (PSPB), which is only produced by the placenta of the growing fetus. BioPRYN® is a proven, accurate, convenient, and cost-effective method for identifying open animals, allowing you to confidently manage your animals. 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.
