The TH-3. Thyroid Health panel contains 7 tests with 10 biomarkers .
Brief Description: The TH-3 Thyroid Health panel is a comprehensive set of tests designed to provide an in-depth evaluation of thyroid function and autoimmunity. This panel assesses the levels of thyroid hormones, including the active and inactive forms, and checks for antibodies that indicate an autoimmune thyroid disorder.
Collection Method: Blood Draw
Specimen Type: Serum
Test Preparation: Specifc to TSH: Specimen collection after fluorescein dye angiography should be delayed for at least 3 days. For patients on hemodialysis, specimen collection should be delayed for 2 weeks.
According to the assay manufacturer Siemens: "Samples containing fluorescein can produce falsely depressed values when tested with the Advia Centaur TSH3 Ultra assay."
When and Why the TH-3 Thyroid Health Panel May Be Ordered
Healthcare providers may order the TH-3 Thyroid Health panel for individuals exhibiting symptoms of thyroid dysfunction, such as unexplained weight changes, mood disturbances, temperature sensitivity, and energy level fluctuations. It is particularly useful for diagnosing autoimmune thyroid diseases like Hashimoto's thyroiditis or Graves' disease and for monitoring the progression and treatment of thyroid disorders.
What the TH-3 Thyroid Health Panel Checks For
- T3 Reverse: Measures the inactive form of T3, providing insights into thyroid hormone metabolism and potential issues with thyroid hormone conversion.
- T3 Total: Assesses the total amount of triiodothyronine in the blood, reflecting overall thyroid hormone production.
- T3 Free: Measures the unbound and biologically active form of T3, offering insights into the functional thyroid hormone available to body tissues.
- T4 Total: Evaluates the total amount of thyroxine, including both bound and free T4, to assess the thyroid gland's output.
- T4 Free: Measures the unbound portion of thyroxine, providing a direct indicator of the hormone available for physiological actions.
- Thyroid Peroxidase Antibodies (TPOAb): Checks for antibodies against thyroid peroxidase, an enzyme involved in thyroid hormone production, indicative of autoimmune thyroid disease.
- Thyroglobulin Antibodies (TgAb): Measures antibodies against thyroglobulin, a protein involved in thyroid hormone storage, also suggesting autoimmune involvement.
- Thyroid Stimulating Hormone (TSH): A central regulator of thyroid function, with its levels reflecting the pituitary gland's response to circulating thyroid hormone levels.
Getting a Deeper Understanding of Your Thyroid Health
For an even more comprehensive assessment, the TH-4 Thyroid Health panel expands on the TH-3 panel by including tests for TSH Receptor Binding Antibody and Thyroid Stimulating Immunoglobulin (TSI). These additional markers are particularly useful in diagnosing and managing Graves' disease, providing a detailed picture of thyroid autoimmunity and function, making it superior for complex thyroid conditions.
Conditions or Diseases the TH-3 Thyroid Health Panel Can Check For
The TH-3 Thyroid Health panel is instrumental in diagnosing and managing autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease. It also helps in evaluating more subtle forms of thyroid dysfunction and monitoring the effectiveness of treatments for thyroid disorders.
Use of TH-3 Thyroid Health Panel Results by Healthcare Professionals
Healthcare professionals analyze the TH-3 Thyroid Health panel results to diagnose thyroid disorders, determine the autoimmune status, guide treatment decisions, and monitor the progression of thyroid diseases. The detailed thyroid hormone profile, along with autoimmune markers, provides crucial information for these purposes.
The TH-3 Thyroid Health panel offers a thorough evaluation of thyroid function and autoimmunity, providing essential insights for diagnosing and managing thyroid disorders. By combining detailed assessments of thyroid hormones with autoimmune markers, this panel enables healthcare providers to identify underlying thyroid conditions, tailor treatment strategies effectively, and monitor patient outcomes, ensuring comprehensive thyroid health management.
We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
