<<Disclaimer: Verify this information before applying it to your situation.>> I was diagnosed back in July 99...my brother just had the blood test done. His results were 2 negative & one positive....can anyone explain? Below is a portion of the email he sent me. Does anyone know if these mixed results mean he has CD? I just got my blood test results from the doctor. The gliadin and reticulin antibody tests were negative, but the endomysial antibody test was positive. As the Dr. explained, the endomysial test is more sensitive than the gliadin test, and indicates some level of intestinal villi atrophy. He wasn't sure what the mixed results indicated as far as diagnosing Celiac's or not. He recommended I stay on my gluten-free diet for another 4-5 weeks and have another blood test done. Since the villi should repair itself quickly, the endomysial test should be negative by then. Regardless of those results, I'll probably want to see a GI for follow-up and a biopsy at that time also.
