Have you ever heard of the FT4 test? This test is important for checking thyroid health. The thyroid is a small gland in the neck that plays a significant role in regulating body metabolism.

The FT4 test measures the level of free thyroxine hormone in the blood. This hormone has a major influence on various bodily functions, such as heart rate, body temperature, and weight. So, if this hormone level is not normal, it can impact your health.

Usually, doctors will recommend the FT4 test if symptoms of thyroid disorder are present, such as drastic changes in weight, irregular heartbeats, or easily falling hair. This test can also help doctors monitor patients who have already been diagnosed with a thyroid disorder.

The procedure is easy. It only requires a blood sample taken from the arm. There's no need to fast or make any other special preparations; in other words, this examination can be done anytime.

FT4 test results can inform doctors whether someone is experiencing hyperthyroidism or hypothyroidism. From there, doctors can provide appropriate treatment to maintain your thyroid hormone balance.

So, if you feel something isn't right with your body, don't hesitate to consult with a doctor and get an FT4 test!
