Canine Total Thyroxine (cTT4) Test Kit

Canine total thyroxine (TT4), the full name of which is the total amount of free thyroxine in dogs (free thyroxine total), is an important indicator for evaluating the thyroid function of dogs. It refers to the total amount of free thyroxine (thyroxine not bound to proteins) in the blood. fTT4 is usually measured through blood tests.

Clinical application:

• Diagnosis of Hyperthyroidism:

Hyperthyroidism is one of the common endocrine diseases in dogs. An elevated cTT4 level is usually an important indicator of hyperthyroidism. For example, when dogs show symptoms such as weight loss, increased appetite, restlessness, and rapid heartbeat, detecting cTT4 is helpful to determine whether there is a problem of hyperthyroidism.

• Health Check for Senior Dogs: 

As dogs age, the risk of thyroid dysfunction increases. Regular cTT4 testing for senior dogs helps detect thyroid-related problems early and enables timely intervention measures to be taken, improving the dogs' quality of life and lifespan. 

• Monitor the Therapeutic Effect:

For dogs that have been diagnosed with hyperthyroidism and are undergoing treatment (such as drug therapy or radioactive iodine therapy), regular detection of cTT4 can assist veterinarians in evaluating the effectiveness of the treatment plan. If the cTT4 level gradually returns to normal after treatment, it indicates that the treatment is working; conversely, if the cTT4 level continues to increase or shows no significant change, the treatment plan may need to be adjusted.
