Q5: Can the Thyroid Function Test diagnose all thyroid disorders?

A: The Thyroid Function Test is an essential tool in diagnosing thyroid disorders, but additional tests and clinical evaluations may be required for a comprehensive diagnosis. Your healthcare provider will determine the appropriate diagnostic approach based on your symptoms and test results.

Q6: What are the T3 and T4 tests for thyroid?

A: T3 (Triiodothyronine) and T4 (Thyroxine) are thyroid hormones that play a crucial role in regulating metabolism and energy production in the body. T3 is the active form, and T4 gets converted into T3 as needed.

Q7: When T3 is high and T4 is normal?

A: Elevated T3 levels with normal T4 levels could indicate a hyperthyroid condition, such as subclinical hyperthyroidism or thyroiditis. Further evaluation is needed to determine the cause.

Q8: Which thyroid test is best?

A: The combination of TSH, Free T4, and TPO antibodies provides a comprehensive view of thyroid function. However, the best test depends on your specific symptoms and the clinical context. Your healthcare provider will guide you.

Q9: What foods control thyroid?

A: Foods rich in iodine, selenium, zinc, and tyrosine can support thyroid health. Examples include seafood, dairy products, nuts, seeds, and lean proteins. Consult a healthcare professional before making significant dietary changes.

Q10: Is uric acid related to thyroid?

A: There is no direct link between thyroid function and uric acid levels. Uric acid is related to conditions like gout and kidney problems. Thyroid disorders primarily affect metabolism and energy regulation.
