Chromogranin A (CgA) is a protein released from neuroendocrine cells. The CgA test may be used to help detect, diagnose, and/or monitor neuroendocrine tumors, especially carcinoid tumors. In either case, neuroendocrine tumors are frequently associated with increased concentrations. The marker for neuroendocrine tumors is chromogranin A, which often . Therefore evaluation of CgA is not valuable as a screening test in the. Chromogranin A, due to its primary expression throughout the neuroendocrine system, is a widely accepted biomarker for the assessment of neuro-endocrine.

The specificity of the test is about 95%, this means that 95% of the time if the CgA level is normal and there is no disease present. Chromogranin A levels can be. Chromogranin A can be used, in conjunction with other testing modalities, as a diagnostic tool, but caution is advised since it is elevated in.

Aim: To correlate the baseline and change of chromogranin A (CgA) levels with patient Percentage changes in paired CgA tests (ΔCgA) of more than 17% can . Chromogranin A or parathyroid secretory protein 1 (gene name CHGA) is a member of the granin family of neuroendocrine secretory proteins, i.e., it is located in.
Serum CGA and urine 5-hydroxyindolacetic acid (5-HIAA) are considered the most useful biochemical markers and are first-line tests in disease surveillance of . Chromogranin A. Ordering Recommendation. Assay aids in monitoring but is not recommended for diagnosis of carcinoid tumors. Assay may be. They also do tests to learn if cancer has spread to another part of the body from A blood test to measure chromogranin-A, a protein produced by tumor cells.
