Chromogranin A **

The Chromogranin A (CgA) test is used to measure the level of Chromogranin A, a protein produced by nerve and endocrine cells in the body, especially cells in the adrenal cortex, pancreas, and neuroendocrine cells. CgA levels in the blood can be elevated in certain medical conditions, especially endocrine tumors.

You may be asked to fast before having your blood drawn. Fasting means not eating or drinking anything but water for 8 to 12 hours before your test. Some medications can affect the results of your CgA test. For that reason, your doctor may ask you to stop taking certain medications before testing.
