The Free T4 (Free Thyroxine) Test measures the amount of unbound or free T4 hormone circulating in your blood. T4 is a thyroid hormone produced by the thyroid gland that helps regulate metabolism and growth.

Why is the Free T4 Test Important?

  1. Thyroid Function: Helps assess the function of the thyroid gland, specifically the production and release of T4 hormone.
  2. Metabolism Regulation: T4 influences metabolism, affecting how the body uses energy and maintains body temperature.
  3. Diagnosis of Thyroid Disorders: Used in diagnosing conditions such as hyperthyroidism (elevated T4 levels) or hypothyroidism (low T4 levels).

When Should You Get a Free T4 Test?

  • Thyroid Symptoms: Symptoms such as unexplained weight changes, fatigue, hair loss, sensitivity to cold or heat, or changes in heart rate.
  • Thyroid Disease Monitoring: For individuals with known thyroid disorders undergoing treatment or medication adjustments.
  • Pregnancy: To monitor thyroid function during pregnancy, as thyroid hormones play a critical role in fetal development.
  • Routine Health Check: Sometimes included in thyroid panels or when thyroid function is being assessed.
