Q:
What is the chromogranin A, ECL Blood Test?

A:
Chromogranin A (CgA) is a protein released by neuroendocrine cells. The chromogranin A test is used to detect tumors including carcinoid tumors, insulinomas, small cell lung cancers, and neuroblastomas.

According to the study, CgA is a useful tool in the monitoring of enterochromaffin-like (ECL) hyperplasia secondary to treatment with acid secretion inhibitors or atrophic gastritis. The chromogranin A, ECL blood test is used to measure the amount of chromogranin A in the blood to detect ECL hyperplasia.

It should be notice that the normal range of CgA is 1.9-15 ng/mL. Elevated levels of CgA may indicate tumors.
