P021 - THYROID PROFILE, FREE(FT3,FT4,TSH) Detail

The Thyroid Profile, Free (FT3, FT4, TSH) is a comprehensive blood test used to evaluate the overall functioning of the thyroid gland by measuring three key hormones: Free Tri-iodothyronine (FT3), Free Thyroxine (FT4), and Thyroid Stimulating Hormone (TSH). The thyroid gland plays a vital role in regulating the body’s metabolism, energy production, heart rate, temperature control, growth, and hormonal balance. FT3 and FT4 represent the active thyroid hormones available to body tissues, while TSH is produced by the pituitary gland and controls the production and release of thyroid hormones.

This profile is commonly recommended for the diagnosis and monitoring of thyroid disorders such as hypothyroidism, hyperthyroidism, goiter, autoimmune thyroid diseases, and pituitary dysfunction. Abnormal levels of these hormones may indicate an underactive or overactive thyroid gland, hormonal imbalance, or response to thyroid medication. Clinical interpretation is usually done by correlating all three parameters together along with patient symptoms and medical history for accurate assessment.
