True Chromogranin a concentrations in plasma from patients with small intestinal neuroendocrine tumours.

Conclusion: Available commercial immunoassays measure CgA in plasma with gross variability. Three commercial CgA immunoassays discriminate so poorly between health and disease that they should not be used. The highest diagnostic accuracy was obtained with processing-independent measurement of total CgA concentrations in plasma. PMID: 32352887 [PubMed - as supplied by publisher]
