The HealthCheckUSA STTM Basic Thyroid is a group of tests that includes Free T3, Free T4 and TSH that are often ordered together to help evaluate thyroid gland function and to help diagnose thyroid disorders. The tests included in a thyroid panel measure the amount of thyroid hormones in your blood. These hormones are chemical substances that travel through the bloodstream and control or regulate your body’s metabolism—how it functions and uses energy.

TSH is produced by the pituitary gland and is part of the body’s feedback system to maintain stable amounts of the thyroid hormones T4 and T3 in the blood. When concentrations decrease in the blood, the pituitary is stimulated to release TSH. The TSH in turn stimulates the production and release of T4 and T3 by the thyroid gland. When the system is functioning normally, thyroid production turns on and off to maintain constant blood thyroid hormone levels.

Free T4 measures the free, unbound thyroxine levels in your bloodstream. Free T4 is typically elevated in hyperthyroidism, and lowered in hypothyroidism. Free T4 levels represent the level of hormone available for uptake and use by cells. T4 is the storage form of thyroid hormone, called levothyroxine or l-thyroxine, and it’s “main” purpose is to convert to the active hormone T3. Because the free levels of T4 represent immediately available hormone, free T4 is thought to better reflect the patient’s hormonal status than total T4.

Free T3 measures the free, unbound levels of triiodothyronine in your bloodstream. T3 is the active thyroid hormone, also called triiodothyronine, and can be the most important lab you will do. Free T3 is considered more accurate than Total T3. Free T3 is typically elevated in hyperthyroidism, and lowered in hypothyroidism.

Thyroid Test Recommendations
We recommend a thyroid test for anyone who:

  • has a family member with thyroid disease,
  • has been diagnosed with chronic fatigue syndrome
  • is a woman in or near menopause,
  • has recently given birth,
  • has other pituitary or endocrine disease, or
  • is experiencing symptoms of thyroid disease.

When Should You Suspect Your Thyroid?

Your thyroid gland regulates all cells in your body and the rate at which they should function. Too little hormone, called hypothyroidism, puts you into a dragging slowdown. This is a problem for more than 10 million Americans – of whom 8 million don’t know it. Too much hormone, called hyperthyroidism, increases your momentum. This problem affects some 4.5 million Americans, but at least 600,000 of them have yet to be diagnosed.

Thyroid disease symptoms cover quite a range, and if you suspect that you or a loved one is suffering from one of these disorders, you should consider a thyroid test or thyroid tests. Here are some thyroid disease symptoms:

  • fatigue or depression,
  • enlargement of the thyroid gland or discomfort in the neck area,
  • weight change,
  • pregnancy problems,
  • always feeling too hot or too cold,
  • heart rate or blood pressure irregularities,
  • digestive problems like diarrhea and more frequent bowel movements and urination, and/or
  • muscle and joint fatigue.

Of course, this is not a comprehensive thyroid disease symptom list, and we encourage people who have questions about thyroid disease to consult their doctor or simply order a thyroid test or a few select thyroid tests to get some answers.
