Q. What is BioPRYN? A. BioPRYN is a blood pregnancy test for ruminants and has a specific appeal for the commercial U.S livestock industries, because it delivers fast, accurate, safe and economical pregnancy results. Q. What does the test name stand for? A. The test's name is partial acronym for "Pregnant Ruminant Yes/No," and the technology works on all ruminants, A specific test using ELISA technology, which produces fast results, has been develp for use exclusively in cattle, sheep, goats bison and deer. Q. How does BioPRYN detect pregnancies? A. BioPRYN evaluates the blood ( more specifically, the serum or Plasma) of ruminants for protein call Pregnancy Specific Protein B (PSPB). PSPB is produced by the placentas, and therefore pregnant animals will the protein in their blood. This makes the test more accurate than earlier attempt at pregnancy diagnosis the evaluated blood or milk for progesterone or other hormones that can occur in normally cycling animals. Q. How early in pregnancy can animals be tested with BioPRYN? A. Cows can be tested at 28 days or later after breeding, Heifers can be tested at 25 days or later after breeding. Lactating cows have residual PSPB from the previous pregnancy until 90 days after calving. To be safe in not getting a false-positive result, breeders are cautioned to take the sample at 28 days or more after breeding and 73 days or more after calving. This if a cow is bred at 45 days post-breeding sample, which is 73 days after calving.. If she is bred at 55 days after calving, then the post-breeding sample should be taken at 23 days so that the cow is 73 das post-calving. Animals that are detected open and then be immediately returned to aggressive breeding programs using Lutalyse, CIDRs and/or OvSynch. Q. What is the accuracy of BioPRYN? A. BioPRYN has been shown to have an overall accuracy rate of 97 %. In fact, the test is over 99% accurate if the cow is called not pregnant, with less than 1% showing false-open (false-negative). Correct open detections is very important because giving Lutalyse or other synchronizing drugs is misdiagnosed pregnant cows will cause abortion. the false-pregnant (false-positive) rate for the test is appoximatley 5%. In practice, high-producing dairy cows tend to show slightly higher false-positive rates of 7-8%, especially during period of extremely. hot weather. It is presumed that a portion of these variance is due to hirer early embryonic death, and not to test inaccuracy. Q. How much does BioPRYN cows? A. the test itself cost $2.75, plus the cost of a sample tube and needle. Shipping expenses also must be added if the tests are mailed in. Q. How long does it take to receive the test results? A. the test requires 24 hours from laboratory set-up to reporting. A report will be emailed between 9:00and 10:00AM the following morning the arrive.
