Pregnancy Testing

  • Conduct on milk (fresh, frozen or preserved) or serum samples from cattle, sheep or goats.
  • Confirm pregnancy through pregnancy specific proteins (PAG). PAGs are released by the placenta during pregnancy and are specific to pregnancy unlike some other chemical indicators, such as progesterone.
  • Results comparable to traditional methods.
  • 98% Accurate (98.8% Sensitivity, 97.4% specificity); comparable to palpation and ultrasound.

Sample Types

When To Use

  • Test as early as 28 days post-breeding through dry-off.
  • Must be at least 60 days post-calving.

Results

  • Available within 24 hours of sample receipt.
  • Quickly access results online through a personalized database system.
  • Results reported as pregnant (>0.25), open (<0.1) and recheck (0.1-0.25) based on the levels of PAGs present. “Recheck” results should be verified by herd veterinarian or retested.

Price

Additional Information

Testing Supplies

CentralStar’s laboratories provide sample analyses on milk, blood, fecal, and tissue samples for a variety of production, disease and health-related traits. More than 6 million samples are processed annually using state-of-the-art equipment and techniques including infrared spectroscopy, flow cytometry, ELISA, PCR, and more.

Diagnostic tests are intended to identify diseases for animal health, and do not determine the “safety” of milk.
