Has anyone heard of such a high CGA? I am being worked up for a carcinoid or NET. I take PPI's and hav chronic renal insufficiency which I read will make the test higher...but could it make it 5600 higher? Normal for this lab is <130. Hope someone else has had this level and has some info to share. Thank you
