TSH

TSH (Thyroid Stimulating Hormone) is the primary screening test for thyroid disorders. Produced by the pituitary gland, TSH regulates thyroid hormone production. Elevated TSH indicates primary hypothyroidism (failing thyroid). Low TSH suggests primary hyperthyroidism (overactive thyroid) or secondary hypothyroidism (pituitary dysfunction). TSH is the most sensitive marker of thyroid dysfunction and is recommended for all adults periodically, especially those with fatigue, weight changes, depression, or family history. TSH trends guide thyroid medication dosing (levothyroxine). Combined with Free T-4, TSH provides comprehensive thyroid assessment. Available at Raazi Lab Islamabad. Price: ₨900.
