The Complete Thyroid Assessment checks all thyroid hormones essential for optimal heart and muscle function, digestion and brain development, and regulating the body’s metabolic rate.

The thyroid is a small, butterfly-shaped gland in the front of your neck. Your thyroid gland produces two main hormones, thyroxine (T4) and triiodothyronine (T3), that influence every cell in your body. They maintain the rate at which your body uses fats and carbohydrates, help control your body temperature, influence your heart rate, and help regulate the production of protein.

This test will measure your levels of thyroid hormones from which we can help you understand if you may be experiencing thyroid dysfunction – which will have an impact on many aspects of your body.

This is what the test will measure:

Thyroid-Stimulating Hormone

Thyroid-stimulating hormone, or TSH, is a hormone produced by the pituitary gland and is responsible for controlling the production of the thyroid hormones T3 and T4. The hormone TSH is considered the most sensitive marker for screening for thyroid diseases and conditions.

Free T3

T3 (triiodothyronine) is a hormone produced by the thyroid gland. While it is less abundant than T4, T3 is considered the more active of these two thyroid hormones. Together, T3 and T4 help determine the rate at which every cell in the body uses energy. 

Free T4

T4 (thyroxine) is the predominant hormone produced by the thyroid gland. Together, T3 and T4 help determine the rate at which every cell in the body uses energy. 

T3 (total)

T3 exists in two forms in the blood: Bound T3, which is attached to proteins that help transport T3 through the body, and Free T3, the less abundant form, that circulates unattached. The T3 total test, the most common type of T3 blood test, measures both the bound and free forms of T3.

T4 (total)

Total T4 measures both bound and unbound T4. and is a measure of the total amount of thyroxine in the blood, which is primarily produced by the thyroid gland. A total T4 test can help diagnose hypothyroidism or hyperthyroidism, monitor thyroid hormone replacement therapy, and identify thyroid problems in children. It can also provide insight into the overall health of the thyroid gland and help guide further diagnostic testing or treatment.

Thyroid Peroxidase (TPO) Antibodies

Thyroid peroxidase antibodies are antibodies that can bind to thyroid enzymes, suppressing thyroid function. If TPO antibodies are elevated, this could be suggestive of an autoimmune condition.
