How is carcinoid syndrome diagnosed?

Carcinoid syndrome is diagnosed when a doctor suspects carcinoid tumors based on your symptoms. First, your doctor will do urine and blood tests to look for the chemicals that are produced by the tumors, as well as the broken-down byproducts of those chemicals. If these chemicals are detected, your doctor will do imaging tests, such as MRIs or CT scans to find where exactly the tumor is located in your digestive system. Sometimes your doctor will not be able to determine where the tumor is based on imaging alone, so they may need to do exploratory surgery to find it.
