Thanks so much for all the advice. I got some helpful information form the Gluten File that I will take to my appointment tomorrow. I know they are working on a referral to a GI specialist for me so if she doesn't want to do the testing, I'm sure he will.

Cara, I pulled out some of my previous labs and I found a B12 test from May 2006. It was 390 and it says the normal range is 200-1100. Is that too low?
I also looked up a few others after reading Table 3 in the article you mentioned. It gives the rountine blood screenings that could give early detection to malabsorption resulting from Celiac Disease. Here's what I found:

Alkaline Phosphatase = 45 -- normal range 42-121
Protein Albumin = 3.8 -- normal range 3.2-5.5
Folate = 15.7 -- doesn't give a normal range

As far as anemia goes, I'm not sure....my WBC, RBC, Hemoglobin and Hematocrit have all been slightly low or borderline low for quite some time. I also had a hematologist tell me a few months ago that my iron stores are very, very low. I even had Ketones in my urine for a while that was assumed to be from malnutrition when my weight drastically dropped.

Anyways, thanks again for all the input and I will let you know how things turn out with my Dr.
