TSH (THYROID STIMULATING HORMONE) IS A HORMONE PRODUCED BY THE PITUITARY GLAND THAT REGULATES THYROID FUNCTION. IT STIMULATES THE THYROID GLAND TO PRODUCE THYROID HORMONES, WHICH CONTROL METABOLISM, BODY TEMPERATURE, AND HEART RATE. ABNORMAL TSH LEVELS CAN INDICATE THYROID DISORDERS SUCH AS HYPERTHYROIDISM (OVERACTIVE THYROID) OR HYPOTHYROIDISM (UNDERACTIVE THYROID). BY MEASURING TSH, HEALTHCARE PROVIDERS CAN DIAGNOSE AND MONITOR THYROID CONDITIONS.

IT IS USED TO DEFINITIVELY DIAGNOSE G6PD DEFICIENCY, A GENETIC DISORDER THAT CAN CAUSE A SEVERE TYPE OF ANEMIA CALLED HEMOLYTIC ANEMIA IN RESPONSE TO CERTAIN MEDICATIONS, FOODS, OR INFECTIONS.
