My PCP ordered a 5HIAA based on his opinion that I have carcinoid syndrone. It came back in the normal range today. I do not know if that means I don't have cancer or what. I think I read on one of the medical clinic websites that one should go ahead and run other tests such as chromagranin-A (CgA). I live in a rural area with overworked PCPs. Any direction on this? My GASTRO says I also have EPI which I am having trouble finding a medicine I can tolerate. I wish I lived near a large city where I had access to specialists. I am just lucky that a GASTRO is 200 miles away. All other specialists are 3-400miles away. Appreciate any advice.
