Celiac was diagnosed through a blood test (the doctor did not say that cheryl did not eat gluten so a month and a half before the test I did not eat gluten) the blood test done is: transglutaminase (iga) ab = 8.5 you / ml endomysial ab = 1: 5 borderline and through genetic testing hla-dq2 and hla-dq8 test conclusions: available: (hla dqb 1 * 02) hla-dqb1 * 02 hla-dqa1 * 05 no biopsy was performed as the doctor said we would be required to return to eating gluten for at least 3 months and my daughter did not agree because the gluten caused her a lot of bloating and abdominal pain. It is important for me to note that after we lowered gluten the abdominal pains still exist but different abdominal pains. No iga ttg test performed.
