If any of the above items are missing - test results may be delayed!


Does the animal have to be a certain age to be tested?
There is no age requirement. Samples may be collected as soon as the animal is born. However, if pulling hair samples we recommend that you wait approximately 24 hours after birth of the animal in order to allow the hair follicles to fully develop.
