A cortisol urine test is also called a urinary free cortisol test or UFC test. It measures the amount of cortisol in your urine. Cortisol is a hormone produced by the adrenal glands, which are located on top of the kidneys. Cortisol is often released in response to physical or emotional stress.
Doctor may order a cortisol urine test if you’re showing symptoms of a medical condition that causes cortisol levels to rise or fall.
