A member asked:

What is the normal range for a chromogranin a my test shows high with 21.00 nc/ml?

A doctor has provided 1 answer

Variable: Each lab may have slightly different ranges of values. When elevated there is a suggestion of the presence of tumor, but not which type of tumor, although usually carcinoid, pheochromocytoma or other neuroendocrine tumors.

Dr Fowler and 2 doctors agreed
