Chromogranin (CGA)

The protein chromogranin A (CgA) is secreted by neuroendocrine cells. These are cells that respond to nervous system inputs by releasing hormones. They can be present in all of the body's organs.

The chromogranin A (CgA) test is used as a tumour marker. To help diagnose carcinoid tumours, it can be ordered alone or combined with a 5-HIAA test. CgA can also be utilised to look for additional malignancies from neuroendocrine cells.

Why done? 

When a doctor suspects that your signs and symptoms are caused by a carcinoid tumour or another neuroendocrine tumour, a CgA test is ordered along with another testing.

The following are some possible signs and symptoms:

The face and neck are flushed (appearance of deep red colour, usually with sudden onset)

• Diarrhoea, nausea, vomiting, abdominal discomfort, and evidence of intestinal obstruction are all symptoms of intestinal blockage.

• A heart rate that is quite fast

• Chest pain, wheezing, coughing, and breathing difficulties.

• This test may be ordered regularly to assess treatment efficiency and detect tumour recurrence.


You'll have blood extracted from an arm vein. 

How does one prepare for the test? 

It may be necessary to fast or stop taking certain drugs. Any advice from your healthcare professional or laboratory should be followed.
