Eighteen of the primary (core) markers are available in a testing kit manufactured by Thermo Fisher. However, 3 of the core markers and all 12 of the secondary (extra) markers are not available in any kits. It may be that some service providers only use the commercially available kit or have not added the 12 secondary markers to their tests, which means their tests cost less to run.
Canine Genetic Testing is different because we routinely test all 33 markers currently recommended by ISAG. While this results in higher running costs overall, we feel that it is important to provide the information for all of these markers.
