Being gluten-free may well mess up a blood test. The blood test is looking for antibodies to gluten - your body's reaction to the protein. If you haven't been having any gluten, there's nothing for your body to react to, hence no proteins. (Ok, that's an oversimplification, the levels of antibodies will decline over time, not instantly drop to zero, but two weeks - depending entirely on your body - may be enough to bring you down below "normal" range.) I had the same thing happen - I was gluten-free for 2-3 weeks before my blood tests and the results came back inconclusive, though the diet was obviously helpful.
