The TSH Test: Your Thyroid's Report Card
The Thyroid Stimulating Hormone (TSH) test is the most important and sensitive test for thyroid function. It's like a report card for your thyroid gland. High TSH levels usually indicate an underactive thyroid (hypothyroidism), while low levels suggest an overactive thyroid (hyperthyroidism). However, interpreting TSH alone isn't always straightforward.
Free T4 and T3: The Active Players
Free T4 (thyroxine) and Free T3 (triiodothyronine) tests measure the actual thyroid hormones circulating in your blood. Think of T4 as the reserve player and T3 as the star athlete. T4 is converted to T3, which is the active form that affects your body's metabolism. These tests help paint a complete picture of your thyroid function.
Thyroid Antibody Tests: Uncovering Autoimmune Issues
Antibody tests, such as TPO (thyroid peroxidase) and TgAb (thyroglobulin antibodies), can reveal if your immune system is attacking your thyroid. This is crucial for diagnosing conditions like Hashimoto's thyroiditis or Graves' disease. High antibody levels are like red flags, signaling potential autoimmune thyroid problems.
