What is the TSH Test?
TSH (Thyroid Stimulating Hormone) is the single best screening test for thyroid disorders. Produced by the pituitary gland, TSH tells your thyroid how much hormone to make. High TSH means your thyroid is underactive (hypothyroidism), and low TSH means it's overactive (hyperthyroidism). TSH changes before T3/T4 levels do, making it the earliest marker.
