The TH-4. Thyroid Health panel contains 9 tests with 12 biomarkers .
Brief Description: The TH-4 Thyroid Health panel represents the most comprehensive evaluation in the series, designed to assess thyroid function extensively, including thyroid hormone levels, autoimmunity, and specific markers indicative of autoimmune thyroid diseases. This panel is particularly valuable for diagnosing complex thyroid conditions and monitoring autoimmune thyroid disorders.
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-4 Thyroid Health Panel May Be Ordered
Healthcare providers may order the TH-4 Thyroid Health panel for individuals with symptoms suggestive of thyroid dysfunction or autoimmune thyroid disease, such as Graves' disease or Hashimoto's thyroiditis. It's also ordered for patients with known thyroid conditions to monitor the disease progression and the effectiveness of treatment, especially in cases where conventional treatment has been ineffective or when a detailed autoimmune profile is necessary.
What the TH-4 Thyroid Health Panel Checks For
- T3 Reverse: Measures the inactive form of T3, providing insight into thyroid hormone metabolism and potential conversion issues.
- T3 Total: Assesses the total amount of triiodothyronine in the blood, reflecting overall thyroid hormone production.
- T3 Free: Evaluates the unbound and biologically active form of T3, offering insights into the functional thyroid hormone available to body tissues.
- T4 Total: Measures the total amount of thyroxine, including both bound and free T4, to assess the thyroid gland's output.
- T4 Free: Assesses 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, suggesting autoimmune involvement.
- TSH Receptor Binding Antibody (TRAb): Indicates an immune response targeting the TSH receptor, characteristic of Graves' disease.
- Thyroid Stimulating Hormone (TSH): A central regulator of thyroid function, with its levels reflecting the pituitary gland's response to circulating thyroid hormone levels.
- Thyroid Stimulating Immunoglobulin (TSI): Assesses the presence of antibodies that stimulate the thyroid, characteristic of Graves' disease.
Conditions or Diseases the TH-4 Thyroid Health Panel Can Check For
The TH-4 Thyroid Health panel is instrumental in diagnosing and managing autoimmune thyroid diseases such as Graves' disease and Hashimoto's thyroiditis. It also helps in evaluating more subtle forms of thyroid dysfunction and in distinguishing between various thyroid disorders.
Use of TH-4 Thyroid Health Panel Results by Healthcare Professionals
Healthcare professionals use the results from the TH-4 Thyroid Health panel 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 specific autoimmune markers, provides a comprehensive overview necessary for effective management.
The TH-4 Thyroid Health panel offers an extensive evaluation of thyroid function and autoimmunity, providing essential insights for diagnosing and managing complex thyroid disorders. By combining detailed assessments of thyroid hormones with specific markers of thyroid autoimmunity, this panel enables healthcare providers to identify underlying 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.
