A1/A2 Testing
A1/A2 (beta-casein)
The A2 genotyping assay identifies the A1 and A2 beta-casein status of individual animals, providing insight for strategic breeding to develop A2 herd status. The A2 isoform of beta-casein is potentially better digested than the A1 isoform. Milk containing only the A2 isoform (A2/A2) is currently being marketed as an alternative to traditional fluid milk. Accuracy: blood and tissue 99%, and milk: 94% accurate.

Additional Information
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.
