Neuroendocrine: Chromogrannin A is a marker of a wide range of neuroendocrine tumors, including pheochromocytoma, carcinoid, others. There are false positives related to diet and meds, although 3000 seems very high (although you don't state the normal range). Your symptoms (?flushing; ?hypertensive spells) would help guide the workup. You need to see a doc who is expert in this.
