Let’s Start With the Problem

The thyroid gland is a small, butterfly-shaped gland located at the base of the neck just below the Adam’s apple. Although relatively small, the thyroid gland plays a huge role in our body, regulating the body’s metabolic rate, as well as influencing the function of many of the body’s most important organs, including the heart, brain, liver, kidneys and skin. Ensuring that the thyroid gland is healthy and functioning properly is vitally important to the body’s overall well-being. If your thyroid is not functioning properly, it can produce too much thyroid hormone, which causes the body’s systems to speed up (hyperthyroidism); or it can create too little thyroid hormone, which causes the body’s systems to slow down (hypothyroidism).

Work Toward Wellness

Before you can improve your thyroid function, you must start with a detailed assessment that offers real, meaningful insights. Measure the four critical thyroid hormones to help verify your thyroid gland’s condition. With this actionable information, you can take the necessary steps to take control of your body and overall health.

Panels Tested

Thyroid Stimulating Hormone

Thyroid Stimulating Hormone, or TSH, is a hormone produced by the pituitary gland and is in charge of triggering the thyroid gland to produce thyroxine (T4) and triiodothyronine (T3). Knowing the levels of TSH in the body can help you understand your overall thyroid health and where dysfunction may be present.

Thyroid Peroxidase

Thyroid Peroxidase Antibodies, or TPOab, is a panel that helps indicate whether or not the cause of a thyroid condition is due to an immune or autoimmune disorder. Measuring the TPOab is an effective way of testing for all possible influences on thyroid health.

Free T3

Free T3 is unbound (or free) triiodothyronine and is the second of the two main thyroid hormones . T3 is the more potent of the two thyroid hormones, and plays an important role in hyperthyroidism (overactive thyroid). Thyroid hormones play a vital role in how the body uses energy, our metabolism, and keeping all our organs, including the heart, brains, and muscles, working properly.

Free T4

T4, or thyroxine, is the major thyroid hormone secreted by the thyroid gland. The “Free T4” is the portion of thyroxine that is unbound and thus free to enter and affect the body’s tissues. Together with T3, both thyroid hormones work together to regulate our metabolic rate, heart/digestive function, muscle control, brain development, and mood development.
