Chromogranin A (CgA) is a member of the granins, a family of acidic proteins found in abundance in (neuro)endocrine cells (e.g. in chromaffin cells) and in some tumors. Like other granins, CgA has a granulogenic role in secretory granule biogenesis and is stored in these organelles. CgA is partially processed differentially in various ...The neuroendocrine tumors associated with the Zollinger-Ellison syndrome are characterized by elevated rates of gastric HCl secretion and upper gastrointestinal ulcer disease. Gastrin levels >500-600 pg/mL in a patient with basal acid hypersecretion often indicate gastrinoma, but antral G-cell hyperplasia cases can have gastrin levels >500 pg ...Specimen Required.

Chromogranin A (CgA) is a 439-amino acid protein with a molecular weight of 48 to 60 kDa, depending on glycosylation and phosphorylation status. It is a member of the granin family of proteins and polypeptides. Granins are widespread in endocrine, neuroendocrine, peripheral, and central nervous tissues, where they are found in secretory ... Well-differentiated neuroendocrine tumours (NETs) are rare, slow-growing tumours. Chromogranin A (CgA) has replaced the 24-h urine collection of 5-hydroxyindoleacetic acid and has become the most important tumour marker in the monitoring of NET during and after treatment and is recommended by the European NeuroEndocrine Tumor Society (Korse et al, 2009; O'Toole et al, 2009). The Chromogranin A test may be used to help detect, diagnose, and/or monitor neuroendocrine tumors, especially carcinoid tumors. Chromogranin A is a protein released from neuroendocrine cells. These are cells that secrete hormones in response to signals from the nervous system. The neuroendocrine tumors associated with the Zollinger-Ellison syndrome are characterized by elevated rates of gastric HCl secretion and upper gastrointestinal ulcer disease.
