Chromogranin A (CgA) is a protein commonly secreted by neuroendocrine tumor cells. A blood test measures CgA as a tumor marker. In patients treated with somatostatin analogs, CgA tests should be timed carefully with their somatostatin analog treatment. False-positive levels of CgA, due to several issues, including the use of proton pump ...Chromogranin A (CgA), which is an intrinsically disordered protein that belongs to the granin family, was first discovered in the bovine adrenal medulla, and later identified in various organs.

This review is focused on chromogranin A (CgA), a hydrophilic glycoprotein present in large dense core vesicles of neuroendocrine cells. Despite being long identified as the most useful NEN-related circulating marker, clinical application of CgA is controversial. CgA assays still lack standardization, thus hampering not only clinical management ...
