Hello @eei and welcome to the NETs support group on Mayo Connect. I see that your oncologist is requiring you to have a CgA test prior to your appointment with him. The CgA test is just one of many that are often requested when we are diagnosed with a neuroendocrine tumor. Here is some information about the CgA blood test as well as other labs that are often done when this type of diagnosis is made, https://www.carcinoid.org/for-patients/diagnosis/diagnosis-and-follow-up-tests/.

As this is your first post, please share as you are comfortable doing so, a little about your history with neuroendocrine cancer? For example, how long ago were you diagnosed? How are you feeling?
