My daughter has been diagnosed with Lactose Intolerance and Irritable Bowel Syndrom. These are both symptoms of Celiac. She had the blood test and it came back as a false positive. This means the IGG were irregular but the IGA and IGE were negative. Does anyone know exactly what this means. The doctor said it means she does not have celiac. Could he be wrong? Any information you can give me would be helpful.
Thank you

well, I guess you could call it inconclusive, but until you can otherwise verify that she's not celiac, you can't call it a false positive. celiac is NOT an IgE mediated response (from my understanding it can also cause an IgE response due to inflammation, but that's not the primary mechanism) (that's a "classic" allergy), and if he didn't do a total IgA count, a low IgA reading doesn't really tell you anything. The fact that the IgG was elevated suggests that she _could_ be positive. Based on a single raised IgG, my doc had me do a dietary test (which turned out positive).

Hi Robin- Welcome :)

In my opinion blood test are not conclusive or accurate. I suffered for over a year with the classic Celiac symptoms including losing 40lbs in 2 months and my doc still thought I had IBS. I had an endoscopy, which showed patchy inflammation and he STILL thought it was IBS because my blood-work came back negative! The docs think they have to see everything in black and white and when they don't they quickly dismiss celiac disease. Of course there are other docs who think celiac disease is so rare and they his/her patient couldn't possibly have it!!!

I finally decided to order the stool panel tests from Enterolab and received positive results and immediately began a gluten-free diet! This particular stool test is more sensitive than blood and you do not have to be on gluten for it to be accurate. I could tell a difference in the way I felt within days and very thankful that I took this route and do not have to live in pain on a daily basis!

Good luck to you and your daughter, I hope she feels better soon! :D
