What is the normal range for chromogranin A?

What is the normal range for chromogranin A?

There is a normal level of Chromogranin A in the blood, and the range currently is less than 39ng/l.. Abnormal levels can vary form forty to the thousands. The sensitivity of the test for CgA is about 80%, this means that 80% of the time abnormal levels are correctly associated with disease.

Does high chromogranin A always mean cancer?

Chromogranin A concentration can be used as an indirect predictor of cancer. There is a correlation between the staging of the disease and concentration of CgA. As mentioned above, higher CgA is observed for metastatic disease compared to localized disease [41].

Is chromogranin A tumor marker?

The chromogranin A (CgA) test is used as a tumor marker. It may be ordered alone or in combination with a 5-HIAA test to help diagnose carcinoid tumors. CgA may also be used to detect the presence of other tumors arising from neuroendocrine cells.

Does carcinoid show up in blood tests?

Blood and urine tests can be very helpful in diagnosing carcinoid syndrome in patients who have symptoms that might be caused by it. Many GI carcinoid tumors, especially those in the small intestine, make serotonin (also called 5-HT). It is probably the cause of at least some of the symptoms of carcinoid syndrome.

What foods affect chromogranin levels?

Avoid foods that contain high amounts of mines, nitrogen-containing organic compounds, as they can trigger the release of serotonin and other hormones. These foods include fatty meats, smoked or salted fish, aged cheeses, and even chocolate. There are other changes you can make to your diet to better manage symptoms.

Does carcinoid show on CT scan?

Imaging tests may be used to locate the primary carcinoid tumor and determine whether it has spread. Your doctor may start with a CT scan of your abdomen, because most carcinoid tumors are found in the gastrointestinal tract. Other scans, such as MRI or nuclear medicine scans, may be helpful in certain situations.
