What should we prepare for chromogranin A test?
Chromogranin A test is a test to help diagnose and monitor carcinoid tumors and other neuroendocrine tumors. When you have symptoms suggestive of a carcinoid tumor, such as flushing, diarrhea, or wheezing, this kind of test is suggested. It will draw blood samples from a vein in your arm. Before taking chromogranin A test, fasting may be required.
