DNA testing for health, appearance and pedigree verification in horses

Learn about one of the tests we do: DNA profile

There are a number of reasons to get a DNA profile for your horse. The most common one is to confirm your horse's parentage.

Parentage verification is done using DNA profiles from the parent(s) and the offspring. DNA profiles from other laboratories can be used for parentage verification, but you will need to provide a full copy of the report rather than a DNA number.

Siblings can't be used for parentage verification.

A second reason to get a DNA profile is to have a way to prove your horse's identity in cases of loss or theft. Microchips are also used for this purpose.

DNA profiles are also useful if you are investigating infertility and suspect sex reversal or Turners syndrome (seen in mares that have a single X chromosome). A DNA profile includes markers on the sex chromosomes. Our report will flag results that are inconsistent with the nominated sex. A report showing two separate alleles for the LEX3 marker will rule out Turners syndrome.
