CHROMOGRANIN A
About test
What does CHROMOGRANIN A measure?
This test measures chromogranin A, a protein that may be released by certain neuroendocrine cells and tumours. It may be used to support the evaluation or monitoring of neuroendocrine tumours, alongside clinical findings, imaging, and other laboratory tests. Chromogranin A levels can also be affected by some non-cancerous conditions and medicines, so results should be interpreted by a healthcare professional in the appropriate clinical context.
