Thyroid Test

Thyroid Test

A thyroid test usually refers to blood tests that measure how well your thyroid gland is working. Common tests include:

  • TSH (Thyroid-Stimulating Hormone) – often the first and most important screening test.
  • Free T4 (Thyroxine) – measures the active thyroid hormone level.
  • Free T3 (Triiodothyronine) – sometimes checked if thyroid problems are suspected.
  • Thyroid antibodies – may help diagnose autoimmune thyroid conditions such as Hashimoto’s thyroiditis or Graves’ disease.

These tests can help diagnose:

  • Underactive thyroid (hypothyroidism)
  • Overactive thyroid (hyperthyroidism)
  • Autoimmune thyroid disorders

If you have thyroid test results (for example, TSH, T3, and T4 values), paste them here and I can help explain what they mean. If you’re asking about when to get tested or how to prepare for the test, I can help with that as well.
