A TSH-sensitive blood test, also known as a thyroid-stimulating hormone (TSH) test, is a type of test that measures the levels of TSH in the blood. TSH is a hormone produced by the pituitary gland that stimulates the thyroid gland to produce hormones that regulate the body's metabolism. The TSH-sensitive test is used to evaluate the overall function of the thyroid gland and can help diagnose conditions such as hyperthyroidism and hypothyroidism.
