Thyroid Health - Advanced Lab Panel

The Thyroid Health - Advanced Lab Panel panel contains 8 tests with 11 biomarkers.

The Thyroid Health - Advanced lab panel contains all of the tests in the Thyroid Health - Basic and Thyroid Health - Basic Plus lab panels, plus TBG (Thyroxine Binding Globulin) and TSI (Thyroid Stimulating Immunoglobulin). This advanced thyroid panel thoroughly assesses your thyroid function and can help identify both hypothyroidism and hyperthyroidism.

The Thyroid Health - Advanced lab panel includes the following tests:

  • T3 Uptake
  • T4 (Thyroxine), Total
  • T4, Free
  • TSH
  • T3 Total
  • T3, Free
  • T3 Reverse (RT3), LC/MS/MS
  • Thyroid Peroxidase and Thyroglobulin Antibodies

This advanced thyroid panel gives you a complete look at how your thyroid works and can help determine if you have hypothyroidism or hyperthyroidism. If you are experiencing symptoms such as fatigue, weight gain or loss, hair loss, mood swings, or difficulty concentrating, this panel can help determine if your thyroid is the root cause.

This panel can also be used to evaluate your response to treatment and optimize your medication levels if you have been diagnosed with a thyroid condition. Regular monitoring of your thyroid function is especially important if you are pregnant or planning to become pregnant, as thyroid disorders can have serious consequences for both mother and child.

The Thyroid Health - Advanced lab panel is easy to order, and results are typically available within 1-2 business days. Ordering this panel through Ulta Lab Tests is convenient, affordable, and confidential - there are no doctor's orders required, and all of our tests are conducted by Quest Diagnostics laboratories.

Also known as: Reverse T3, Reverse Triiodothyronine, RT3, T3 Reverse RT3 LCMSMS, Triiodothyronine Reverse

T3 Reverse, LC/MS/MS

Reverse T3 produced in the thyroid comes from the conversion of the storage hormone T4. Your body, especially the liver, can constantly be converting T4 to RT3 as a way to get rid of any unneeded T4. In any given day approx. 40% of T4 goes to T3 and 20% of T4 goes to Reverse T3. However in any situation where your body needs to conserve energy and focus on something else, it will change the above percentages, changing the conversion of RT3 to 50% or more, and the T3 goes down, down. Examples are emotional, physical, or biological stress, such as being chronically or acutely sick (the flu, pneumonia, etc), after surgery, after a car accident or any acute injury, chronic stress causing high cortisol, being exposed to an extremely cold environment, diabetes, aging, or even being on drugs like beta blockers and amiodarone.

Also known as: Triiodothyronine

T3, Total

Triiodothyronine (T3) is a thyroid hormone. It plays an important role in the body's control of metabolism.

T3 Uptake

T3 uptake is also known as T3 Resin Uptake (T3RU) or Thyroid Uptake. It estimates how much thyroid hormone-binding proteins are available in the blood through a calculation based on levels of T3 or T4 added to a person's blood specimen.

Also known as: Free T3, FT3, T3 Free

T3, Free

This test measures the amount of triiodothyronine, or T3, in the blood.

Also known as: T4 Thyroxine Total

Free T4 Index (T7)

FTI stands for the Free Thyroxine Index and is also sometimes referred to as T7. It is a calculated value determined from the T3 uptake test and total T4 test and provides an estimate of the level of free T4 in the blood.

T4 (Thyroxine), Total

This test measures the amount of thyroxine, or T4, in the blood. T4 is one of two major hormones produced by the thyroid gland. The total T4 test is used to help diagnose hyperthyroidism and hypothyroidism. It is a useful test but can be affected by the amount of protein available in the blood to bind to the hormone.

Also known as: Free T4, FT4, T4 Free

T4, Free

The free T4 test is not affected by protein levels. Since free T4 is the active form of thyroxine, the free T4 test is may be a more accurate reflection of thyroid hormone function.

Thyroglobulin Antibodies

Measurement of thyroglobulin antibodies is useful in the diagnosis and management of a variety of thyroid disorders including Hashimoto's thyroiditis, Graves Disease and certain types of goiter.

Thyroid Peroxidase

Also known as: Thyroid Stimulating Hormone, Thyroid Stimulating Hormone (TSH), Thyrotropin


A TSH test is a lab test that measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland. It tells the thyroid gland to make and release thyroid hormones into the blood.
