Blood and urine hormone tests measure the amount of adrenal hormones in your blood and urine. A 24-hour urine test may also be done. To do this, you save your urine in a special container for 24 hours. It's then sent to a lab to check the amounts of certain hormones. All of these tests can be very helpful in figuring out what kind of cancer you have.
Activating and suppression tests might be done. To do these, you're given medicines to increase or decrease certain adrenal hormones. Blood or urine tests will then show if the hormone levels changed. Hormones made by a cancer tumor often don't change with these medicines.
