I took a blood test to see if i had a gluten allergy a yr ago and nothing showed up, i have been gluten free for a yr and feel better.what does it mean?

Keep on keeping on: Regardless of the test, if you feel better there has to be something about gluten-containing foods that doesn't agree with you. Don't think too much about this. Do what makes you feel better.

Gluten sensitivity: How you feel is the ultimate test of whether you're sensitive to gluten. There are many mechanisms through which gluten may cause someone to feel worse ; they don't all show up in blood tests, which are good at diagnosing celiac disease but not the much more common non-celiac gluten sens.
