Basic Thyroid Function Tests

Evaluate Your Thyroid Health with Three Key Hormones

• Free Triiodothyronine (FT3): Measures the active form of thyroid hormone; helps assess metabolism.
• Free Thyroxine (FT4): The primary hormone produced by the thyroid gland.
• Thyroid Stimulating Hormone (TSH): Produced by the pituitary gland; the most sensitive indicator of thyroid function.

👥 Who Should Get Tested?

• Individuals with unexplained fatigue, weight changes, or hair loss
• Women (thyroid disorders are more common in women)
• Adults over 35 as part of routine screening
