TSH testing

TSH testing measures the level of thyroid-stimulating hormone (TSH) in your blood, which is produced by the pituitary gland to regulate your thyroid gland. The thyroid controls many body functions, like energy and metabolism. If TSH levels are high, it may indicate your thyroid is underactive (hypothyroidism). If levels are low, it could mean your thyroid is overactive (hyperthyroidism). This test helps doctors diagnose thyroid problems, monitor treatment effectiveness, and guide appropriate management to keep your body's functions balanced.
