How is Pheochromocytoma Diagnosed?

If your health care provider suspects pheochromocytoma, some standard tests that are done are:

  • Biochemical analysis to test plasma metanephrines (a byproducts of hormones in the blood)
  • 24-Hour urine tests to measure hormone levels.

Next, CT scans or MRI testing will help your doctor find a mass, its location, and the extent of the problem. Pheochromocytoma happens in less than 1 out of 100 people with high blood pressure and more than 95 out of 100 of those cases are not cancer.
