Clinical Significance. Chromogranin A, LC/MS/MS - Chromogranin-A (CgA) is an acidic glycoprotein expressed in the secretory granules of most normal and neoplastic neuroendocrine (NE) cell types, where it is released together with peptide hormones and biogenic amines. Neuroendocrine tumors (NETs) are a form of cancer that differ from other ... Chromogranin A (CgA, NM_001275.3) is a 456-amino acid hydrophilic acidic protein of the granin family, expressed in a variety of endocrine, neuroendocrine, peripheral and central neural tissues (Bartolomucci et al., 2011). CgA functions as a key component of dense-core secretory granules and modulates the storage and processing ...Serotonin, 24 Hour, Urine. Useful For. The diagnosis of a small subgroup of carcinoid tumors that produce predominately 5-hydroxytryptophan (5-HTP) but very little serotonin and chromogranin A. Follow-up of patients with known or treated carcinoid tumors that produce predominately 5-HTP but very little serotonin and chromogranin A.Additional Information. Troponin T (TnT) is a component of the contractile apparatus of the striated musculature. Although the function of TnT is the same in all striated muscles, the cardiac isoform of TnT originating exclusively from the myocardium clearly differs from skeletal muscle TnT.
