I had the test about 2 months ago. Simple blood draw. I have difficult to diagnose symptoms and read about it in AARP. Since then, I have seen it other places. I took it based on the cleveland clinic article. I suggest that you read about it on the Grail website. What I like about it is that in a study they found it had some accuracy for cancers that normally do not have any routine screening test available such as ovarian cancer and pancreatic cancer. Plus I had a positive on the cologard test and a follow up colonoscopy. But that the colonoscopy did not cover small bowel cancer. What I do not like about it is that it was $945 out of pocket. I do believe it is the screening of the future. They just need to make it covered by medicare and other health plans.
