What is the Chromogranin A Test?

Chromogranin A is a protein secreted into the blood by neuroendocrine cells. Its measurement can diagnose a neuroendocrine tumour. Neuroendocrine cells moderately discharge this protein into the blood. A high level of chromogranin A in the blood indicates a neuroendocrine tumour. A doctor may order this test if you have symptoms of neuroendocrine tumours such as facial or neck flushing, diarrhoea, intestinal blockage, rapid heartbeat, chest pain, or difficulty breathing. Chromogranin is normally > 93ng/mL.

In addition to carcinoid tumours, this test also helps diagnose thyroid carcinomas and small cell lung cancer. It can help evaluate the efficacy of neuroendocrine tumour treatments and tumour recurrence.

Hepatic failure can cause mild chromogranin A elevations, while renal insufficiency can cause major chromogranin A.
