FREE T3 Test

The Free T3 (Triiodothyronine) Test measures the amount of unbound or free T3 hormone circulating in your blood. T3 is one of the thyroid hormones that plays a crucial role in regulating metabolism, energy production, and growth.

Why is the Free T3 Test Important?

1. Thyroid Function: Helps assess the function of the thyroid gland, specifically the production and release of T3 hormone.
2. Metabolism Regulation: T3 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 T3 levels) or hypothyroidism (low T3 levels).

When Should You Get a Free T3 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.
