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 assay is greater than 99 percent accurate when an animal is categorized as open, giving producers confidence to administer a prostaglandin shot and restart a synchronization program. The false-pregnant (false-positive) rate for the test is approximately 5 percent. It is presumed that a portion of this variance is due to early embryonic death, which is a challenge regardless of which method is used for pregnancy detection.
