  • Centronuclear Myopathy in Labrador Retrievers

CNM is an inherited autosomal recessive disorder and is characterized by weight loss, awkward gait, and exercise intolerance.

  • Collie Eye Anomaly (CEA), Chorodial Hypoplasia

In affected dogs, the choroid does not develop properly and is thinner than normal, which can result in vision loss and retinal detachment.

  • Copper Toxicosis (Copper Storage Hepatopathy)

Copper Toxicosis (CT) is an inherited autosomal recessive disorder in which a dog’s system accumulates excess copper instead of excreting it naturally, which can result in severe damage to the liver.

  • Cystinuria in Newfoundlands and Labradors

Cystinuria is a metabolic disorder that can cause stones in the urinary tract. This test is exclusively for Labrador Retrievers and Newfoundlands.

  • Degenerative Myelopathy (DM) in Canine Breeds

DM is a degenerative disease of the spinal cord characterized by muscle weakness in the hind limbs. This disease can eventually leading to paraplegia.

Exercise Induced Collapse (EIC)


  • Dogs clinically affected by Exercise Induced Collapse (EIC) often begin to exhibit leg weakness that is followed by a complete collapse after just 5 to 15 minutes of strenuous activity.

  • Hereditary Nasal Parakeratosis (HNPK) in Labrador Retrievers

HNPK-affected dogs develop dry, rough crusts on the tip of the nose. In extreme cases, the dog’s nose cracks, causing severe discomfort. This test is exclusively for Labrador Retrievers.

  • Multidrug Resistance 1 (MDR1)

MDR1-affected dogs are at risk of developing neurologic symptoms from several common drugs. Find out if your dog is affected.

Progressive Retinal Atrophy, Progressive Rod-Cone Degeneration (PRA-prcd)
PRA-prcd is inherited as an autosomal recessive disease. Degeneration of both rod and cone photoreceptor cells of the retina of PRA-prcd affected dogs usually occurs at 3 to 5 years of age or later.

  • Uric Acid DNA Test (Hyperuricosuria)

Hyperuricosuria, or elevated uric acid level in the urine, is inherited as an autosomal recessive disorder and is characterized by the formation of bladder stones and occasional kidney stones.

  • von Willebrand’s Disease Type 1

vWD is the most common inherited bleeding disorder in canines. Type I vWD is characterized by abnormally-low production of blood-clotting protein.
