What Is a Total T4 and Total T3 Test?

Total T4 and Total T3 Test - Genesis Lifestyle LabsA Total T4 and Total T3 Test is a type of thyroid function test. Also known as TFT, it measures the levels of triiodothyronine (T3) and thyroxine (T4) in your blood. The goal is to check to see if your thyroid is functioning properly and effectively releasing the hormones you need into your bloodstream to optimize your health and well-being.

Why Is the Thyroid Important?

The thyroid is a small, butterfly-shaped gland in your neck. It works to produce the hormones we need for a healthy body. Despite how small the thyroid is, it has a significant impact on everything from your weight to heart function, digestive health, reproduction, temperature regulation, and more.

Do Men Need Thyroid Tests?

Although a Total T4 and Total T3 test is often associated with women's health, men also benefit from them. They can help diagnose and manage thyroid-related conditions, as well as get to the root cause of confusing symptoms. Men who have a family history of thyroid disease have an increased risk of thyroid disorders, which requires testing. Existing autoimmune diseases, such as celiac disease or radiation exposure to the neck area, can also cause thyroid dysfunction in men and women.
