Hi Carl

I have spoken to my doc again about this and he did confirm that my CEA levels were measured by the cyst fluid which as you stated indicates if there is mucin or not. He said that as I had so low CEA Cyst Fluid they are not 100% this is an IPMN but they will treat it as such.He did indicate that there is a blood test CEA as well (not CA-19-9) but that is not really used for Pancreatic diagnosis. My CA-19-9 was extremely low as well so I am counting myself lucky compare to others
