What blood tests show Carcinoids?
The chromogranin A (CgA)* blood test is a good marker to help detect and monitor the activity of carcinoid tumors.

What happens if Chromogranin is high?
Impaired kidney function. Elevated CgA also occurs in the case of impaired kidney function due to reduced renal clearance. The higher the degree of renal failure, the higher the CgA concentration, and the result may reach the level found in neuroendocrine tumors [13].
