Why am I having this test?

What is being tested?
This test measures the amount of metanephrine and normetanephrine in your blood. Metanephrine and normetanephrine are substances that appear in your blood after adrenaline and other hormones break down. Increased levels of these substances in your blood may be a sign of having a pheochromocytoma tumor.
What kind of sample is taken?
A blood sample is required for this test. It is usually collected by inserting a needle into a blood vessel.
