T3 Test for Hypothyroidism in Dogs

The T3 test is one of the most common ways of identifying the condition known as hypothyroidism in your dog. Hypothyroidism affects a large number of dogs, although it isn't found very often in many other types of pets. This condition can be very serious and may develop suddenly or over a longer period of time. If you have detected any of the symptoms of hypothyroidism in your dog, take him in to the vet for a further set of examinations and to have his blood tested by means of a T3 test. This will allow you to identify and treat his hypothyroidism promptly.

Hypothyroidism and the T3 Test

Hypothyroidism is a condition which affects the thyroid gland. This gland is situated in your pet's neck and is responsible for producing two major hormones. These hormone chemicals, called T3 and T4, are responsible for regulating and helping with a number of important bodily functions for your pet. These functions include metabolism, growth, digestion and much more. Without a proper level of these hormones in the body, these other systems and functions may be compromised in some way and your pet's overall health will decline.

Hypothyroidism is a condition where the levels of T3 and T4 in your pet's blood are lower than normal due to an inactive thyroid gland. By reading the levels of these hormones that are present in your dog's blood, a vet can determine what the problem is and whether or not your pet has a thyroid condition.

Administering the T3 Test

The T3 test is a blood test. You'll need to take your dog to the vet's office to have him draw a small sample of blood. While most dogs are not bothered or hurt by this procedure at all, some may become nervous or fidgety. If this is the case, the vet can help by giving your pet a mild sedative to help calm him during the blood test.

After sampling your pet's blood, the vet will send the sample to the lab for further testing. At the lab, technicians will mix various chemicals in with the blood in order to determine the levels of T3. By comparing the levels of T3 found in your pet's specific reading against the levels of this chemical and hormone that are standard and healthy for dogs of a comparable age, gender and breed, the technicians can determine whether your pet has lower than normal T3 levels.

Addressing Hypothyroidism

After you've received the T3 test results that confirm your pet's hypothyroidism, work with your vet to determine a schedule of hormone supplements to help balance out his system. You may also wish to include a set of dietary and other lifestyle changes at your vet's recommendation. Continue to monitor your dog's hormone levels closely to be sure that his body is continuing to function as it should.
