It really depends on what you’re looking for. Etalon Diagnostics, for example, offers insights about a horse's genetic predispositions for health, appearance, and performance and abilities for 149,00 $. However, there’s no completely reliable parentage test.
Alternatively, DDC Veterinary will give you “definitive proof of parentage” for less than $40 (EasyDNA also has a parentage test, but it is much more expensive). Neither of these competitors provides the depth of insights that Etalon offers regarding medical predispositions.
Both EasyDNA and Animal Genetics make you pay separately for each category and test; and if you want the same range, you can end up paying much, much more than you would for Etalon’s Minipanel, which offers most of its services at one flat price.
