thyrotropin-releasing hormone test

thyrotropin-releasing hormone stimulation test (for thyroid function) pituitary release of thyrotropin is assessed by administration of a bolus of thyrotropin-releasing hormone and measurement of serum concentrations of thyrotropin at intervals. If serum levels do not increase within 30 to 40 minutes, the pituitary thyrotrophs are dysfunctional. Called also TRH stimulation t.
