I was going to im you privately but decided to do it here.

If you are lactose intolerant, you should try to be more than just careful. Intolerant means--eat none. On another note, many gluten intolerant/celiac people get false negatives. It's more common to get a false negative! A huge percentage of gluten intolerant can not have dairy either. Once the villi are damaged, then they sometimes can't tolerate dairy either. Sometimes, a person will beable to tolerate dairy in the future. Doctors still do not know enough about gluten intolerance--there is not a test out there yet that can find gluten intolerance before the damage is terrible.

Once you have given lactose intolerance a chance, if you still are having some problems, then try gluten free. If it helps, great, if not, having no gluten can not hurt you and you can always go back.
