One teensy PSA here about celiac and GF diets:

You generally have to be eating gluten regularly to be accurately tested (and certainly to be tested non-invasively) for celiac. If you are gluten-free, you may test falsely negative, as antibody levels will fall fairly rapidly.

Please, please, please-- if you suspect celiac, DO NOT try a GF diet without getting a diagnosis first. It's really important to be monitored for certain sequelae if you have Celiac Disease.

smile There. PSA complete.
