Yes, many here. I guess your blood test is only as good as your lab tech. And false negatives do happen. An endoscopy would tend to be more accurate.

There's a lot of factors here. It's possible to have a negative blood test, but know that it could be a false negative. There is a percentage of people that cannot make type "A" antibodies. A celiac panel should always include a "Total serum" check to determine if this is the case for you. Also lab mistakes can happen and old test kits or kits that have been improperly stored can fail. In strongly suspected cases a negative blood test might be rechecked at another lab.

All that said, I think every bit of research clearly shows that the endoscopy is much less effective than the blood test. The endoscopy has frequent false negatives, because early damage can be hard to pin down, and because damage may be spotty and can be missed with sampling. False positives occur when a tech miss-orients a sample or confuses damage from another digestive condition for celiac related damage.
