Blood Test

Recommended Posts

My bloodtest came out Negative...however I was off gluten for 6 weeks, not knowing you had to be on it. My doctor said go back onto Gluten and take it again. Feeling great for 6 weeks...had three pieces of pizza 2 days ago and now have the runs from hell and my stomach hurts...Anyway, my question is: I know you should be on gluten for three months before the biopsy..what about the bloodwork? Would a week be fine? Or can I just go and eat wheat pasta and a hoagie 1 to 2 days before the bloodwork???

Thanks guys.

People have differing opinions about eating gluten just because their Dr wants to confirm his diagnosis. Some do it but many of us don't want to become ill again so refuse. When my blood tests came back they showed elevated alpha gliadin but a negative tissue transglutaminase. This confused my Dr but I felt so much better even after a week on the gluten-free diet I decided to have the genetic test done. The lab I used, not the one advertized at Celiac.com, showed I was DQ2/DQ2 and had a high risk of developing celiac disease. That was enough confirmation for me, I had the symptoms, did better on a gluten-free diet and will be gluten-free for the rest of my life. This lab also offers fecal tests for the antibodies which are much more sensitive than the blood tests, and fecal tests for food allergies and to assess the maladsorbtion problem. Dr. Fine who runs this lab has Celiac Disease and is considered an authority on celiac disease.

      Correct. I’m doing both in the same go though. Thanks for clarifying before I confused someone. I’m doing a colonoscopy for something else and then they added the endoscopy after the test.

      It is a biopsy but it's not a colonoscopy, it's an endoscopy.

      Well I’m going on the gluten farewell tour so they are about to find out lol. I keep saying biopsy but yeah it’s a scope and stuff. I’m a dummy but luckily my doctor is not.

      The biopsy for celiac disease is done of the small bowel lining and in conjunction with an "upper GI" scoping called an endoscopy. A colonoscopy scopes the lower end of the intestines and can't reach up high enough to get to the small bowel. The endoscopy goes through the mouth, through the stomach and into the duodenum, which is at the upper end of the intestinal track. So, while they are scoping the duodenum, they take biopsies of the mucosal lining of that area to send off for microscopic analysis by a lab. If the damage to the mucosa is substantial, the doc doing the scoping can often see it during the scoping.
