Thyroid Tests
- THYROID Panel (TSH + Free T3 + Free T4)$68.36
This panel includes comprehensive testing of the thyroid stimulating hormone (TSH) in addition to free thyroxine (T4) and free triiodothyronine (T3). This thyroid panel offers a lower cost than buying each hormone separately. If you take biotin, please wait at least 8 hours to get blood drawn. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating.
Learn More - Iodine Blood Test$72.37
Iodine, Serum/Plasma - Iodine is an essential element that is required for thyroid hormone production. The measurement of iodine serves as an index of adequate dietary intake and iodine overload, particularly from iodine-containing drugs.
Learn More - Thyroid Antibody Panel$72.37
These two tests measure antithyroglobulin antibodies and Anti-TPO antibodies that are commonly present in patients with Hashimoto's thyroiditis, Graves disease and other thyroid-related conditions. Antibodies against the protein thyroglobulin can result in the destruction of thyroid cells. TPO antibodies are created when the immune system of a person targets by pure error elements of the thyroid gland or protein, leading to chronic thyroid inflammation, tissue damage, and damage to the thyroid function. Leaving this untreated may cause severe health issues.
Learn More - Hashimoto's Test Panel$165.38
1. TSH (Thyroid Stimulating Hormone) Test The TSH test is crucial for diagnosing Hashimoto's disease. It gauges the level of TSH that the pituitary gland produces, which in turn stimulates the thyroid to produce T4 and T3 hormones. Elevated TSH levels can indicate hypothyroidism, commonly associated with Hashimoto's disease
2. Thyroid Hormone Tests These tests measure the levels of free T3 (free triiodothyronine) and free T4 (free thyroxine) in the blood. A low level of free T4, along with an elevated TSH level, is a key indicator of Hashimoto's disease
3. Thyroid Antibody Tests Most individuals with Hashimoto's disease have thyroid peroxidase (TPO) antibodies in their blood. Testing for these and other thyroid-related antibodies is a significant step in diagnosing the condition
4. Thyroglobulin Antibody Test This test screens for antibodies against thyroglobulin, a protein in the thyroid gland. High levels are another marker of Hashimoto's disease
Learn More - Thyroxine-binding Globulin (TBG), Serum$124.34
Thyroxine-binding globulin (TBG) is a globulin that binds thyroid hormones in circulation. It is one of three transport proteins (along with transthyretin and serum albumin) responsible for carrying the thyroid hormones thyroxine (T4) and triiodothyronine (T3) in the bloodstream. Of these three proteins, TBG has the highest affinity for T4 and T3 but is present in the lowest concentration. Despite its low concentration, TBG carries the majority of T4 in the blood plasma.

As low as $68.36
This panel includes comprehensive testing of the thyroid stimulating hormone (TSH) in addition to free thyroxine (T4) and free triiodothyronine (T3).
Learn More - THYROID Panel - COMPREHENSIVE$220.50
This test panel includes most tests needed to more deeply explore the possibility of hypothyroidism and/or Hashimoto's disease diagnosis. It includes: TSH, Free T3, Free T4, Reverse T3, Thyroglobulin Antibody and Thyroid Peroxidase Antibody (Anti-TPO). If you are taking biotin, please stop it 72 hours before the blood draw since it may interfere with hormone blood tests. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating. NOTE: Reverse T3 is analyzed using a specific technique called liquid chromatography/tandem mass spectrometry (LC/MS-MS). There's a special place in the U.S. where these precise machines needed for LC/MS panels run only on two specific days a week. So, sometimes the clock ticks a bit while we wait for samples to return from their initial collection points. Results may take 7 business days.
Learn More - THYROID Stimulating Hormone-TSH$19.68
The thyroid stimulating hormone (TSH) is produced and secreted by the pituitary gland and stimulates the thyroid to produce T3 and T4. When TSH is elevated, low thyroid function may be indicated. If TSH is low it is indicative of high thyroid function. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating.
Learn More - Free Triiodothyronine T3$50.79
T3 or triiodothyronine is the active form of the thyroid hormone. T3 acts as a metabolic throttle for fueling all of the daily cellular functions. Free T3 is the unbound portion of T3 that is biologically active.
Learn More - Free Thyroxine T4$44.08
The thyroid gland produces and secretes T4, otherwise known as thyroxine. Proteins bind to T4 and carry it throughout the bloodstream. Once in the tissues, T4 is released from the proteins and is now free to convert into the more active form called T3. For this reason, many doctors believe that measuring free T4 is a more sensitive test for thyroid hormone production.
Learn More - Reverse T3 Test$79.67
The reverse T3 test has to be done at the same time you do the free T3, and you then measure the ratio between the two by dividing the RT3 into the Free T3. The body produces the benign RT3 naturally to rid itself of excess of T4, but in some cases, such as high or low cortisol, RT3 is produced in excess, which can clog cell receptors from receiving T3. FT3 is usually twenty or more times higher than RT3. NOTE: Reverse T3 is analyzed using a specific technique called liquid chromatography/tandem mass spectrometry (LC/MS-MS). There's a special place in the U.S. where these precise machines needed for LC/MS panels run only on two specific days a week. So, sometimes the clock ticks a bit while we wait for samples to return from their initial collection points. Results may take 7 business days.
Learn More - Thyroglobulin Antibody$44.10
This test measures thyroglobulin antibodies commonly present in patients with Hashimoto's thyroiditis. Antibodies against the protein thyroglobulin can result in the destruction of thyroid cells. This destruction can lead to hypothyroidism. NOTE: Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
Learn More - THYROID Peroxidase Antibodies - TPO Antibodies$33.08
The determination of TPO antibody levels is the most sensitive test for detecting autoimmune thyroid disease (eg, Hashimoto's thyroiditis, idiopathic myxedema, and Graves disease) and detectable concentrations of anti-TPO antibodies are observed in most patients with these disorders. The highest TPO antibody levels are observed in patients suffering from Hashimoto thyroiditis. In this disease, the prevalence of TPO antibodies is about 90% of cases, confirming the autoimmune origin of the disease. These autoantibodies also frequently occur (60%–80%) in the course of Graves disease.
