Free T4 (thyroxine)

Thyroid

The Free T4 test is a blood examination that evaluates the concentration of thyroxine, a hormone produced by the thyroid gland. Thyroxine is crucial for regulating metabolism, energy levels, and growth. This test specifically measures the portion of thyroxine not bound to proteins in the blood, known as “free” thyroxine.

Commonly employed to detect thyroid abnormalities, such as hyperthyroidism or hypothyroidism, the Free T4 test aids in identifying symptoms like fatigue, weight fluctuations, mood changes, and concentration difficulties. Thyroid dysfunction can also impact fertility.

Measuring free thyroxine levels provides insight into thyroid function, helping to ascertain whether hormone production is excessive or deficient.

Given the prevalence of thyroid disorders globally, this test holds significant importance. Prompt diagnosis and treatment of thyroid conditions are vital for enhancing overall health and wellness.
