Test Results --- Thoughts? in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted December 14, 2013 · Report to Admin I know there are a lot of posts like this and so I am sorry that I am creating another one. Any help would be greatly appreciated. My Rheumatologist decided to test me for celiac disease based on some symptoms when I saw her for consistently high C-reactive protein and ESR levels. I have yet to hear back from her regarding these results, as she is on vacation, but I asked the office to fax my blood test results. Any thoughts and feedback on these results would be very helpful. Test Name. Results. Reference Range IGA, serum. 330 mg/dl. 81-463 mg/dl. normal IGG, serum. 1686 mg/dl. 694-1618 mg/dl. high IGM, serum. 133 mg/dl. 38-271 mg/dl. normal Gliadin AB IGA. 77 U. < 20 U. high Gliadin AB IGG. 2 U. < 20 U. normal tTG AB IGG. 2 U/mL. < 6 U/mL negative tTG AB IGA. < 1 U/mL. < 4 U/mL. negative unrelated abnormal results: C-Reactive Protein. 2.6 mg/dl. < 0.8 mg/dl. high ESR, Westergren. 40 mm/hr. 0-20 mm/hr. high Is it possible with these results to say I have celiac disease or will I need a biopsy to get a conclusive diagnosis? I am also seeing a Rheumatologist for another, yet to be diagnosed, autoimmune disease causing the high CRP and ESR bloodwork. Thanks in advance!
