TSH 3rd Generation

Overview

The TSH 3rd Generation, Serum test measures the level of Thyroid Stimulating Hormone (TSH) in the blood using a highly sensitive third-generation assay. TSH is produced by the pituitary gland and regulates the production of thyroid hormones (T3 and T4), which control metabolism, energy levels, body temperature, heart rate, and growth. The enhanced sensitivity of the 3rd generation assay enables the early detection of subtle thyroid abnormalities, making it valuable for diagnosing hypothyroidism, hyperthyroidism, and monitoring thyroid hormone replacement therapy. This test is commonly recommended for individuals experiencing fatigue, unexplained weight changes, hair loss, menstrual irregularities, infertility, or other symptoms suggestive of thyroid dysfunction.

Why Take This Test?
