FT3 (Free Triiodothyronine) and FT4 (Free Thyroxine) are thyroid hormones circulating freely in the bloodstream. They regulate metabolism, growth, and energy levels. TSH (Thyroid-Stimulating Hormone) is produced by the pituitary gland to stimulate thyroid hormone production. High TSH suggests hypothyroidism (underactive thyroid), while low TSH indicates hyperthyroidism (overactive thyroid). FT3 and FT4 levels help diagnose and monitor thyroid disorders, guiding treatment adjustments to maintain hormone balance and overall health.

A free thyroid profile typically includes measurements of Free Triiodothyronine (FT3), Free Thyroxine (FT4), and Thyroid-Stimulating Hormone (TSH). FT3 and FT4 are thyroid hormones that circulate in the bloodstream unbound to proteins, representing the biologically active forms of thyroxine and triiodothyronine. These hormones are essential for regulating metabolism, growth, and energy expenditure throughout the body.

FT3 (Free Triiodothyronine): FT3 is the active form of thyroid hormone that affects cellular metabolism, protein synthesis, and the body’s sensitivity to other hormones.

FT4 (Free Thyroxine): FT4 is the precursor to FT3 and primarily responsible for maintaining metabolic rate, heart and digestive functions, muscle control, brain development, and bone health.

TSH (Thyroid-Stimulating Hormone): TSH is produced by the pituitary gland to regulate thyroid hormone production. Elevated TSH levels typically indicate hypothyroidism (underactive thyroid), whereas low TSH levels suggest hyperthyroidism (overactive thyroid).

A free thyroid profile is crucial for diagnosing thyroid disorders, including hypothyroidism, hyperthyroidism, and thyroid hormone resistance syndromes. It helps clinicians assess thyroid function accurately, monitor treatment efficacy, and adjust medication dosages as needed to maintain hormonal balance and support overall health. Regular testing of FT3, FT4, and TSH is essential for managing thyroid conditions effectively and preventing complications related to thyroid hormone imbalances.
