The Role of Thyroid Function Tests in Monitoring Thyroid Disorders

Thyroid Function

and Health

Thyroid function tests, also known as thyroid panel tests, are critical for monitoring the health of those with existing thyroid disorders. These tests measure the levels of hormones produced by the thyroid, including thyroxine (T4) and triiodothyronine (T3), as well as the brain’s release of thyroid-stimulating hormone (TSH), which helps control the production of these hormones.

Why Are Thyroid Function Tests Important?

Thyroid function tests are used to diagnose and monitor the health of individuals with Hyperthyroidism (overactive thyroid) or Hypothyroidism (underactive thyroid). By determining levels of key hormones, these tests can detect if the thyroid is functioning properly and can help identify underlying health issues, such as autoimmune thyroid diseases or thyroid cancer.

Who Should Get Tested?

It is recommended that those with a family history of thyroid disorders, those experiencing symptoms of thyroid disorder, pregnant women and those taking medications that interfere with the thyroid should get tested. It is also important for those over the age of 60 to get regular thyroid tests, as well as those with diabetes or iodine deficiency.

What Should I Know Before Testing?

When getting a thyroid function test, it is important to be mindful of certain medications and substances that can interfere with the accuracy of your results. These include certain antibiotics, steroids, supplements and contrast agents. If you are taking any of these, you should let your healthcare provider know in advance.

What Are the Benefits of Regular Testing?

Regularly testing hormone levels, especially in those with preexisting thyroid conditions, can prevent long-term health problems by helping to manage existing conditions and detect abnormalities early. Early diagnosis and treatment can help reduce the risk of complications, including heart disease, infertility, osteoporosis, depression and anxiety.
