Genetic testing has opened the doors to improved breeding choices. Not only are the tests more readily available, they also cover a broad range of genetic mutations and are affordable.
In the past, breeding decisions were made by doing test matings between closely related animals in order to uncover recessive diseases. Now, all it takes is a buccal swab.

In the US, UC Davis’s Veterinary Genetics Laboratory or VGL has been the standard by which most others are measured. Dr. Leslie Lyons, now with University of Missouri, still support the lab and works closely with them.
The turn around time is a matter of days for VGL, but the cost is higher than commercial labs. However, that cost does go to supporting the work the lab offers.
Optimal Selection/Wisdom Panel offers a comprehensive panel test for a reasonable price. You can also receive a discount through your TICA membership.
The results take an average of 2-3 weeks for turnaround time. However, this includes 50 mutations, 27+ traits, blood type, and a diversity percentage. They are adding new mutations to their line up as they become available and consistently adding new features.
