A member asked:
What can be the cause of a result for serum chromogranin a way under reference values?
A doctor has provided 1 answer
No abnormality: There are no known disorders associated with low chromogranin A levels. High levels are also non specific, but can be seen with various endocrine tumors. It is not unusual to find tests where having a value below the normal range is not known to be associated with a medical disorder.
