Question

Quizplus · Accepted Answer

A test performed on urine to determine the amount of epinephrine and norepinephrine present is called catecholamines. Catecholamines are hormones produced by the adrenal glands that help the body respond to stress. Measuring their levels in urine can help diagnose certain conditions such as pheochromocytoma, a rare tumor that can cause high blood pressure and other symptoms. Corticotropin is a hormone that stimulates the production of cortisol from the adrenal gland and is not related to measuring levels of epinephrine and norepinephrine in urine. Protein-bound iodine is a test used to measure thyroid function. Total calcium is a blood test used to measure the amount of calcium in the blood, and is not related to measuring levels of epinephrine and norepinephrine in urine.
