You were diagnosed two years ago. If you have been following a gluten-free diet for two years, it is quite likely that your villi have healed, and will give a negative biopsy result. Likewise, a blood test today would not find antibodies, because you don't make them without gluten, and that's why your villi can heal.
I showed a strong positive on a biopsy in 2000. A repeat procedure a few years later showed no abnormalities. It didn't mean I don't have celiac disease; it meant that my adherence to the diet was successful, and my intestines had healed.
A competent gastroenterologist should know that.
