Chromogranin A is an accurate general marker for neuroendocrine tumors—most patients with pheochromocytomas or paragangliomas have high plasma concentrations of this marker. Grossrubatscher and ...

Measurement of chromogranin A had a sensitivity of 87% and a specificity of 73% when these patients were excluded. Increasing the cut-off value to >270 ng/ml increased the specificity to 89%.

For the last decade chromogranin-A (CgA) has been a well-established marker for neuroendocrine tumor (NET), and N-terminal pro-brain natriuretic peptide (NT-proBNP) has been a useful marker for left ...

22165 Background: Chromogranin A is a member of the granin family of acidic secretory glycoproteins that is found in secretory granules of many endocrine cells including neuroendocrine tumour cells.

Chromogranin A plasma levels predict mortality in COVID-19; De Lorenzo R, Sciorati C, Ramirez GA, Colombo B, Lorè NI, et al. (2022) Chromogranin A plasma levels predict mortality in COVID-19.

Now, the researchers have linked chromogranin B to the human disease. In their initial screen, they sequenced the gene in 452 people of French or French Canadian ethnicity, 194 with familial or ...
