kabons, here is another reason to get a dyed in the wool dx from a GP or GI. You are 20, likely you will have kids some day & since celiac is a genetic disease it's more than possible one or more of your kids could have it. If you have an official dx then it's MUCH easier to get pediatric docs to take the disease seriously & test your kids every couple years b/c of the genetic connection. Your kids, if they end up with celiac, will need an official dx in order to make sure their schools &/or the military take their dietary needs seriously.
Now, if you can get a doc to dx you based in your blood panel then GREAT! That will work. if not, then you will need to consider how this will affect your kids if you don't have an official dx.
