Thyroid & Metabolism

Thyroid disease is often overlooked but affects millions and can cause issues for multiple systems in your body.  Thyroid hormones control your metabolism and how the body uses energy. Metabolism is needed to help regulate essential body functions.

Our panel looks at 3 key hormones (ft3, ft4, TSH) to provide a comprehensive understanding of overall thyroid function and metabolism.

What’s Tested:
TSH (Thyroid Stimulating Hormone)
Free T3 (Triiodothyronine)
Free T4 (Thyroxine)
Thyroperoxidase (TPO) Antibodies

Collection Method:
Finger Prick


Thyroid-Stimulating Hormone (TSH)
In primary hypothyroidism, thyroid-stimulating hormone (TSH) levels are elevated. In primary hyperthyroidism, TSH levels are low. The ability to quantitative circulating levels of TSH is important in evaluating thyroid function. It is especially useful in the differential diagnosis of primary (thyroid) from secondary (pituitary) and tertiary (hypothalamus) hypothyroidism. In primary hypothyroidism, TSH levels are significantly elevated, while in secondary and tertiary hypothyroidism, TSH levels are low or normal.
Elevated or low TSH in the context of normal free thyroxine is often referred to as subclinical hypo- or hyperthyroidism, respectively.

T3 (Triiodothyronine), Free
Normally triiodothyronine (T3) circulates tightly bound to thyroxine-binding globulin and albumin. Only 0.3% of the total T3 is unbound (free); the free fraction is the active form. In hyperthyroidism, both thyroxine (tetraiodothyronine; thyroxine: T4) and T3 levels (total and free) are usually elevated, but in a small subset of hyperthyroid patients (T3 toxicosis) only T3 is elevated.

T4 (Thyroxine), Free
Free thyroxine (fT4) comprises a small fraction of total thyroxine. The fT4 is avaialable to the tissues and is, therefore, the metabolically active fraction. Elevations in fT4 cause hyperthyroidism, while decrease causes hypothyroidism.

Thyroperoxidase (TPO) Antibodies
Disorders of the thyroid gland are frequently caused by autoimmune mechanisms with the production of autoantibodies. Anti-TPO antibodies activate compliment and are thought to be significantly involved in thyroid dysfunction and the pathogenesis of hypothyroidism.
In patients with sub-clinical hypothyroidism, the presence of TPO antibodies, predicts a higher risk of developing overt hypothyroidism, 4.3% per year versus 2.1% per year in antibody-negative individuals. Such patients may be at risk of developing other autoimmune diseases, such as adrenal insufficiency and type 1 diabetes.

How does the process work?

  1. Place your order on our secure website and your kit will arrive in the mail.
  2. Collect your sample and register your kit following the easy instructions provided.
  3. Get your Results! You will receive an email once they are ready to be viewed.

You should receive your kit within 5-7 business days. Once your sample reaches the lab, your results will be available online within 5-7 business days.

Occasionally during holidays and times of high volumes, we may experience up to 2-3 business day increase in processing times. If you have questions, you can always email us directly at

In which states can I be tested?
Our testing is currently available in 46 U.S. states. We currently do not offer tests to residents located in the following states: New York, New Jersey, Maryland and Rhode Island. Each state has different medical regulations and for this reason, we cannot offer services to these 4 states.

Can I use my health insurance or HSA/FSA?
We offer convenient home testing that is typically priced lower than expenses often associated with using insurance, co-pays or deductibles. For this reason, we do not need to work with health insurance.

Most HSA/FSA allow for at home health tests. We do recommend you check with your plan first and submit your receipts if allowed.

Are my test results private?
Bodyhealth IQ follows HIPPA privacy guidelines and your privacy is our top priority. Your results are password protected and available on our portal for you to share with the provider of your choice.
