Chromogranin A (CgA) is the main, nonspecific marker of neuroendocrine tumours (NET). In the adrenals, CgA is produced by chromaffin cells localised in the adrenal medulla. Therefore its measurement in blood might be used as a screening test for pheochromocytoma after the exclusion of other various causes of an increased CgA level. The aim of ...We would like to show you a description here but the site won’t allow us.Sep 24, 2020 ...
