DNA Testing Available for Labradors (as well as other breeds)

There are several DNA tests that can be done for the Labrador Retriever.

PRA testing -

Progressive Rod Cone Degeneration /Progressive Renal Atrophy

The most current one of interest would be the PRCD/ PRA genetic test. There is a link at the top of this page to understand more about PRA.

DNA Profiling -

This is to profile your pedigree'd labrador.A certified sample is taken by a vet or collection officer, veryifying the the dog via microchip, pedigree name and number. A sample is taken. This is then tested to show that dogs unique markers. This is very similar to the human DNA testing for parentage. This is not something breeders are required to do but it is a test that eventually may be required. Alot of breeders are slowly DNA profiling their dogs at the same time as PRA testing. A watermarked certificate is issued with the individual dogs unique test markers and can be ANKC endorsed YES or NO depending on whether the collection is verified by an officer or vet at the time of collection.

Coat Colour Inheritance-

Genetic Technologies is now also doing coat colour testing for some breeds. The Labrador can now be tested for coat colour inheritance. In the Labrador we test for the B loci and the E loci. Dominant and recessive genes. For example

B - black coat colour

b - brown coat colour

E - able to express a dark coat

e - unable to express a dark coat

The dominant gene is usually shown in upper case and the recessive gene is shown in the lower case.

A great site that explains this well with images is at Astrochoc Labradors - click here

EIC (Exercise Induced Collapse)-

This is a fairly new test that can now be done as some working lines do suffer from exercise induced collapse (Labradors, Curly Coated Retrievers etc). Most people may not be interested in this test unless they have or intend to have working labradors eg. Trailling, Retrieving, fly ball etc.

* Here is a website with information on EIC and a video of what a collapse episode looks like - University of Minnesota

This test can be done in Australia by Genetic Technologies Pty Ltd (*Link Below)

This test is done by designated collection agents (usually vets or registered breeders), by a cheek swab or if sending overseas by blood sample. Australia now has the facilities here to do these tests through Genetic Technologies Australia -
