TSH is the most sensitive and commonly used test for evaluating thyroid function. It's produced by the pituitary gland and signals the thyroid to produce hormones. High TSH suggests an underactive thyroid (hypothyroidism), while low TSH suggests an overactive thyroid (hyperthyroidism). This is usually the first test ordered when thyroid problems are suspected.
