Thyroid Function Health

Thyroid Function Tests Explained

Your thyroid is a small gland located in the front of your lower neck. The thyroid produces hormones that regulates your mood, energy levels, and metabolism, which is the rate at which your body uses energy. It produces two main hormones, T3 (triiodothyronine) and T4 (thyroxine).

Thyroid hormone function tests are used to detect thyroid disorders, helping to ensure that they can be diagnosed and treated before complications occur. View sample thyroid test results with lab variations, ranges and explanations.

Do I need a thyroid function test?

Thyroid hormones affect nearly every cell in your body and influence a wide range of critical bodily functions, which means that a poorly functioning thyroid can have serious and widespread consequences. Thyroid disorders affect more than 12 percent of the population in the U.S., according to the American Thyroid Association (ATA), with up to 60 percent of those people unaware of their condition. Studies show women to be eight times more likely than men to experience a thyroid problem.

The ATA recommends thyroid hormone testing in adults starting at age 35, with repeat testing every 5 years. Thyroid screening is commonly prescribed for women during pregnancy and the postpartum period. The American Association of Clinical Endocrinologists (AACE) also recommends routine thyroid screening in older adults.

What are the symptoms of a thyroid problem?

For your thyroid gland to be operating normally, your body needs to produce an adequate supply of thyroid hormones. If hormone levels are below the norm, it is called hypothyroidism. If the levels are higher than normal, it is termed hyperthyroidism.

Hypothyroidism

Hypothyroidism, also commonly called under-active thyroid, is a disorder that occurs when the thyroid gland is not producing enough thyroid hormones, causing metabolism to slow. It may stem from problems with the thyroid gland itself, or with the pituitary gland which produces hormones that help regulate thyroid function. It is typically diagnosed via blood tests, usually after symptoms of hypothyroidism have been noted. These may include:

  • Fatigue
  • Constipation
  • Weight gain
  • Depression
  • Facial puffiness
  • Dry, brittle nails
  • Dry, brittle hair and/or hair loss
  • Weakness
  • Slow heart rate
  • Memory impairment
  • Dry skin
  • Increased sensitivity to cold
  • In severe cases, coma

Often, when hypothyroidism is suspected, a TSH test may be done first to evaluate TSH levels. TSH is secreted by the pituitary gland, and stimulates the thyroid gland to release thyroid hormones when levels drop in the bloodstream. If TSH levels are abnormally high, this can indicate that the thyroid is not responding adequately to repeated calls for more hormones. When this happens, a thyroid panel is typically done. There are numerous other tests that can be done to detect abnormalities in thyroid function. Among them are the radioactive iodine uptake test and a thyroid scan. However, lab tests are the initial step in diagnosis.

Once hypothyroidism is confirmed, additional testing is usually done to help determine the underlying causes of the condition. Common causes of an under-active thyroid include:

  • Hashimoto's disease – an autoimmune disease that causes inflammation of the thyroid gland as the body's own immune system attacks the gland.
  • Thyroid hormone resistance – a condition in which the body becomes unable to use thyroid hormones efficiently.
  • Medications – certain medications can suppress thyroid activity.
  • Thyroid nodules – These are growths, usually benign, that can develop on the thyroid gland to inhibit normal function.
  • Thyroiditis – inflammation of the thyroid gland.

Hyperthyroidism

Hyperthyroidism, also commonly called over-active thyroid, is a condition in which the thyroid gland is producing abnormally high amounts of thyroid hormones T3 and T4, speeding up the metabolism. Symptoms of this thyroid disorder can include:

  • Anxiety
  • Fatigue
  • Tremors
  • Irritability
  • Excessive sweating
  • Clammy skin
  • Increased heat sensitivity
  • Diarrhea and/or frequent elimination
  • Fast or irregular heartbeat
  • Weight loss
  • Increased appetite

Testing for hyperthyroidism, typically done in response to the appearance of symptoms, is also done with blood tests. Often, a TSH test is the first to be done. When testing for hyperthyroidism, a low level of TSH is the marker of a potential problem, since there is no need for the pituitary gland to use TSH to call for more thyroid hormones when the bloodstream is already flooded with an excessive amount of T3 and T4. If low TSH is found, more testing, generally a thyroid panel blood test, is done to evaluate thyroid function in greater detail and help determine the underlying causes of the condition. Common causes of Hyperthyroidism include:

  • Graves' disease – The most common cause of an over-active thyroid, Graves' disease is an autoimmune condition that results in overproduction of thyroid hormones as the immune system damages the thyroid gland.
  • Thyroid nodules – Growths on the thyroid gland, most often non-cancerous, can contain hormone-producing cells, causing excessive production of T3 and T4.

What are normal thyroid hormone levels?

Normal thyroid levels are not absolute numbers. Rather, having your thyroid tested means that your hormone levels will be compared to a "normal range". Following is a guide that will tell you the normal ranges of each of the thyroid hormones:

  • TSH: between 0.4 and 5.0 milli-international units per liter (m IU/L). But, many scientists and doctors believe that some individuals do have thyroid malfunctions with a TSH above 2.5 instead of 5.0
  • T3: between 80 and 180 nanograms per deciliter (ng/dl)
  • T4: between 4.6 and 12.0 micrograms per deciliter (ug/dl)
  • Free T4: between 0.7 and 1.9 ng/dl

Where can I get thyroid testing near me?

If you suspect that you may be affected by a thyroid disorder, whether you have noticed some of the symptoms listed above or are concerned due to a family history of thyroid disease, getting tested is better done sooner than later. Should tested hormone levels yield results that are not within the normal range and a thyroid disorder is likely, pursuing medical treatment and care immediately is critical to maintaining your health and well-being. Why is it so important to take these steps? Because left untreated, thyroid disorders can lead to serious complications that can affect your health for life, including cardiovascular complications, cognitive impairments, infertility, nerve damage and much more – complications that are easily avoided by prompt testing, diagnosis and treatment.
