TSH ( thyroid-stimulating hormone or thyrotropin) is a protein hormone produced by the anterior pituitary gland. The TSH test is frequently the initial test ordered in the evaluation of thyroid function. The TSH test may be ordered when the physician suspects either hyper- or hypothyroidism. In this reflex test, if TSH result is below or above the reference range, a Free T4 will automatically be added on.
