Given family history and your test results, I'd suspect Celiac Disease. If you want the official gold standard diagnosis, go get the biopsy, but do not stop eating gluten before the test...otherwise, the test will be inaccurate.
Otherwise, if you'd rather skip the test, do your own gluten free diet trial for a while (minimum 3 months - it takes 6-8 weeks for gluten to clear from the gut tissues, and another 6-8 weeks for any damage to heal) and see if you notice any improvements. Most people who have a gluten tolerance issue notice improvement fairly quickly.
