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.

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: 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

TSH

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.

The Dr. Thomas Panel #2 Blood Test panel contains 6 tests with 8 biomarkers .

Dr. Thomas Panel #2 Blood Test

The Dr. Thomas Panel #2 Blood Test is a specialized diagnostic panel designed to evaluate thyroid function and detect thyroid-related disorders. This panel provides a comprehensive assessment of thyroid hormone levels, thyroid-stimulating hormone (TSH), and thyroid autoantibodies, helping to identify conditions such as hypothyroidism, hyperthyroidism, autoimmune thyroid disorders, and thyroid dysfunction caused by stress or metabolic imbalances. By analyzing key thyroid biomarkers, this test enables healthcare providers to diagnose thyroid-related conditions, monitor treatment effectiveness, and guide personalized interventions for optimal thyroid health.

When and Why the Dr. Thomas Panel #2 Blood Test May Be Ordered

Healthcare providers may order the Dr. Thomas Panel #2 Blood Test for individuals experiencing symptoms of thyroid dysfunction, including fatigue, weight fluctuations, hair loss, mood changes, sensitivity to temperature, irregular heart rate, and difficulty concentrating. This panel is commonly used to assess individuals with suspected hypothyroidism or hyperthyroidism, as well as those with a family history of thyroid disease. It is also ordered for patients with autoimmune conditions such as Hashimoto’s thyroiditis or Graves’ disease, as these disorders can directly impact thyroid function. Additionally, this test may be used to monitor patients undergoing thyroid hormone replacement therapy or other treatments for thyroid disorders.

What the Dr. Thomas Panel #2 Blood Test Checks For

The Dr. Thomas Panel #2 Blood Test evaluates multiple thyroid-related biomarkers to provide a comprehensive view of thyroid function, hormone metabolism, and autoimmune activity. Each test plays a crucial role in assessing how well the thyroid gland is producing and regulating hormones.

Thyroid Hormone Levels and Regulation

This panel measures various thyroid hormones, including total T3, free T3, reverse T3, and free T4. These hormones are responsible for regulating metabolism, energy production, and overall bodily functions. Evaluating these markers helps determine whether thyroid hormone production is within a healthy range.

Thyroid-Stimulating Hormone (TSH)

TSH is produced by the pituitary gland and regulates thyroid hormone production. Elevated or suppressed TSH levels can indicate thyroid dysfunction, prompting further evaluation to determine whether the issue originates in the thyroid gland or the pituitary gland.

Autoimmune Markers for Thyroid Disease

Autoimmune thyroid diseases, such as Hashimoto’s thyroiditis and Graves’ disease, are diagnosed by detecting thyroid-specific autoantibodies. This panel measures thyroid peroxidase (TPO) antibodies and thyroglobulin antibodies, which indicate an autoimmune attack on the thyroid gland and help differentiate autoimmune thyroid disorders from other thyroid dysfunctions.

Conditions and Diseases the Dr. Thomas Panel #2 Blood Test Can Detect

This test is essential for diagnosing and monitoring thyroid-related conditions. Early detection of these conditions allows for timely intervention and effective management.

Hypothyroidism

Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormones, leading to symptoms such as fatigue, weight gain, depression, and cold intolerance. This panel detects hypothyroidism by measuring low levels of free T3 and free T4, along with elevated TSH levels. If autoimmune hypothyroidism is suspected, positive TPO or thyroglobulin antibodies can confirm Hashimoto’s thyroiditis as the underlying cause.

Hyperthyroidism

Hyperthyroidism is a condition in which the thyroid gland produces excessive thyroid hormones, resulting in symptoms such as weight loss, rapid heartbeat, anxiety, and heat intolerance. The Dr. Thomas Panel #2 Blood Test helps diagnose hyperthyroidism by detecting high levels of free T3 and free T4, along with suppressed TSH levels. If autoimmune hyperthyroidism is suspected, elevated TPO and thyroglobulin antibodies may indicate Graves’ disease.

Hashimoto’s Thyroiditis

Hashimoto’s thyroiditis is an autoimmune disorder in which the immune system attacks the thyroid gland, leading to chronic inflammation and eventual hypothyroidism. This panel helps diagnose Hashimoto’s by detecting elevated levels of TPO antibodies and thyroglobulin antibodies, along with progressively declining thyroid hormone levels.

Graves’ Disease

Graves’ disease is an autoimmune condition that causes the thyroid gland to become overactive, leading to hyperthyroidism. This test detects Graves’ disease by identifying increased TPO and thyroglobulin antibodies, along with abnormal TSH and thyroid hormone levels. Monitoring these markers helps guide treatment decisions for patients with Graves’ disease.

Euthyroid Sick Syndrome (Non-Thyroidal Illness Syndrome)

Euthyroid sick syndrome occurs when thyroid hormone levels are altered due to a severe illness or chronic stress, rather than a direct thyroid disorder. This condition is identified through abnormal reverse T3 levels, which may be elevated while TSH and free T3 remain within normal ranges. This test helps differentiate euthyroid sick syndrome from true thyroid disease.

How Healthcare Professionals Use the Dr. Thomas Panel #2 Blood Test in Treatment and Monitoring

Healthcare providers use the results of this panel to guide treatment and management strategies for thyroid-related conditions.

Managing Hypothyroidism

For individuals diagnosed with hypothyroidism, healthcare providers may prescribe thyroid hormone replacement therapy, such as levothyroxine, to restore hormone levels to a healthy range. Regular monitoring of TSH, free T3, and free T4 ensures that treatment is effective and symptoms are well-managed.

Treating Hyperthyroidism

If hyperthyroidism is diagnosed, treatment options may include antithyroid medications, radioactive iodine therapy, or, in some cases, surgical intervention. Routine testing helps healthcare providers assess thyroid hormone levels and adjust treatment plans as needed.

Monitoring Autoimmune Thyroid Diseases

For patients with Hashimoto’s thyroiditis or Graves’ disease, measuring thyroid antibody levels helps track disease progression and response to treatment. Healthcare providers may recommend anti-inflammatory approaches, immune-modulating treatments, or thyroid hormone therapy based on test results.

Addressing Euthyroid Sick Syndrome

For patients with euthyroid sick syndrome, healthcare providers focus on treating the underlying illness or stressor rather than directly intervening with thyroid hormone therapy. Monitoring reverse T3 levels helps determine whether thyroid hormone metabolism normalizes as the primary health condition improves.

Conclusion

The Dr. Thomas Panel #2 Blood Test is a comprehensive thyroid assessment that evaluates hormone levels, autoimmune markers, and metabolic function. By detecting conditions such as hypothyroidism, hyperthyroidism, Hashimoto’s thyroiditis, Graves’ disease, and euthyroid sick syndrome, this panel provides valuable insights into thyroid health and guides targeted treatment strategies. Healthcare providers use this test to diagnose thyroid disorders, monitor disease progression, and ensure that treatments are effectively managing symptoms and optimizing overall well-being. Regular testing and proactive management based on these results can significantly improve health outcomes for individuals with thyroid dysfunction.
