Thyroid Profile – TSH, Free T3, Free T4
The thyroid gland plays a critical role in regulating the body’s metabolism, energy levels, and hormonal balance. A Thyroid Profile typically includes three main tests: TSH (Thyroid Stimulating Hormone), Free T3 (Triiodothyronine), and Free T4 (Thyroxine). These tests provide a comprehensive picture of thyroid function and are essential for diagnosing and managing thyroid disorders.
TSH is produced by the pituitary gland and regulates the production of T3 and T4 by the thyroid gland. Elevated TSH levels may indicate hypothyroidism, where the thyroid is underactive, while low TSH levels can point to hyperthyroidism, an overactive thyroid condition.
Free T3 and Free T4 are the active thyroid hormones that circulate in the bloodstream. These hormones control the rate at which the body uses energy and are vital for brain development, body temperature regulation, heart rate, and more. Low levels can suggest hypothyroidism, while elevated levels may indicate hyperthyroidism.
The thyroid profile is a routine test for individuals experiencing symptoms like fatigue, weight changes, hair loss, cold or heat intolerance, or mood swings. It is also regularly monitored in patients with existing thyroid conditions and those taking thyroid medications.
By assessing these hormone levels together, clinicians can accurately determine the underlying cause of thyroid dysfunction and initiate the appropriate treatment. Early diagnosis through a thyroid profile ensures better management and improved quality of life for individuals affected by thyroid-related disorders.
