WebChromogranin 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. WebMeasurements of blood serotonin levels may also be taken; however, these are less reliable due to fluctuations. A blood test to measure chromogranin A, a protein produced by tumor cells, is also sometimes performed after diagnosis.

WebChromogranin A (CgA), a secretory protein of neuroendocrine cells, has recently been characterized as a valuable tissue marker in hormonally active and non-functioning neuroendocrine tumors. This study analyzes the role of CgA as a serum marker for different neuroendocrine tumors. WebCgA is a sensitive marker for the diagnosis of PHEO (97.1%) and thoracoabdominal paraganglioma (84.6%). CgA may be useful in the follow-up of nonfunctional PGLs and may also play a complementary role in the early detection of recurrence in secreting PPGLs.
