Please help, my doctor sent me to get tested for Celiac and I went to Quest, I will not be able to see her for a month.  Two sections from my test came back in red, can someone tell me what these results mean? Do I have celiac, what do the red ones mean?

(TTG) AB, IGG = 1.9

(TTG) AB, IGA = <1.0

The next two are in red

Gliadin (Deamidated) AB, IgA = 27.9 H

Gliadin (Deamidated) AB, IGG = 19.3 H

Immunoglobulin A = 280

Your help is appreciated.

Welcome to the forum, Cookie07!

The red ones are positive for celiac disease. You don't have to have all the tests be positive in order for it to point to celiac disease. That's why your doctor ordered several different kinds of tests. What one misses, others may catch. By the way, you weren't already on a gluten free or a reduced gluten diet were you when the blood draw was made?

The next step will likely be an endoscopy with biopsy of the small bowel lining to confirm the results of the blood antibody tests. You should not cut back on gluten before that is done. The endoscopy/biopsy is considered to be the gold standard for diagnosing celiac disease.

What is Quest?

Thank you so much for your help. To answer your question, yes I was still eating gluten when I took the test and the test were preformed by Quest.
 

Your feedback is much appreciated. Have a great rest of your week.

The tTG-IGA is the most popular single test for celiac disease ordered by physicians and, unfortunately and many times the only one. The tTG-IGA combines good specificity for celiac disease and good sensitivity and it is relatively economical. But for whatever reason, according to one study I read, it misses about 20% of those who do have celiac disease from white European extraction and about 80% of those who do have celiac disease from black African decent. So, it's not perfect and your results underscore the value of running several different antibody tests. There is also the possibility that you have NCGS (Non Celiac Gluten Sensitivity) which is considered by some experts to be a precursor (sometimes) to celiac disease.

      Question about biopsy

      By somethinglikeolivia · Posted

      When I underwent a scope three years ago, the GI told me I was negative for celiac because there was no intestinal damage (in spite of multiple strong positive labs). I went back to look at my biopsy report out of curiosity, and found this note: “Localized mild nodular mucosa was found in the duodenal bulb. Duodenum otherwise normal.” The pathology from this scope was negative. Does anyone have any insight into mild modular mucosa and what that could indicate or be a precursor to? I’ve read it can be a sign of celiac or other gut issues like h. Pylori, etc.  Thanks in advance!

      Abnormal Labs, Should I Be Concerned?

      By Ginger38 · Posted

      I also had high eosinophils which I’ve never had before either - could that be due to gluten consumption?

      Positive TTG antibody and negative EMA antibody

      By knitty kitty · Posted

      You're welcome! Be sure the patient eats at least ten grams of gluten per day for a minimum of two weeks prior to repeating antibody testing.   Some people unconsciously reduce the amount of gluten in their diet because the feel unwell.  Three grams of gluten per day is sufficient to produce symptoms.  Only at ten grams or more is the immune system provoked to raise the antibody production high enough so that the antibodies leave the digestive tract and enter the blood stream where they can be measured.   Read the comments below the article...

      Thanks for your response and thoughts. Total IgA is normal. HLA DQ2/DQ8 came as heterozygous and the interpretation of the lab that the risk of coeliac disease is mild to moderate. Thyroid function test is normal. I agree that the best way is to repeat tTG antibodies in 6 months time as the result was not massively high.
