Celiac Panel Results

Rate this topic

Recommended Posts

Hello, I just got my blood test results. I'm currently waiting for an EGD. My TTG-IGA is 4 and my DGP-IgG is 28. Both fall within the "weak positive" range. Would this be considered a positive blood test?

It seems like you are doing the right thing by getting intestinal biopsies.  Make sure your GI takes the appropriate amount and from the right locations.  Have that conversation with him or her in advance, even if it is an email. Start googling to learn more.   Above all, KEEP EATING Gluten DAILY or you will mess up results.

I will be doing all of the above. I guess my question is more about what the chances are of a false positive with these weak positive results? Especially the Dgp-IgG because I have read that it is highly specific.

Two positives, even weak, are probably accurate and are not false positives.  But who knows?   My GI told me I had a weak positive (just a positive on the DGP IgA).  Biopsies revealed some pretty severe damage though.  

I get it.  Denial.  That was me.  I just went in for a routine colonoscopy because I was over 50 and all my friends were getting them.  My GI ordered a complete celiac panel because I had anemia most of my life.  I did not have any GI issues.  Because of work issues, I waited seven weeks for my endoscopy.  I ate every delicious gluteny food I loved.  Like a load of sourdough a day (I am not kidding).  I kind of went overboard and I started to develop GI issues.  So, in my heart, I knew.  The biopsies really confirmed it.  There is no denying a lab report.  

But, I am happy to report that I am doing well and have healed completely!  

Even if you do get a negative biopsy report, consider the gluten free diet.  Why?  The small intestine is vast (size of tennis court) and the damage can be sporadic.  Or maybe you are just starting to develop celiac disease.

Start researching!  It can be your best defense!

My daughter had a single weak positive blood test and there was visible damage observed when she had the endoscopy. Biopsies confirmed celiac disease. The blood results are not always a direct reflection of the degree of damage.

So true!  I had a recent repeat endoscopy which revealed very healthy healed  villi and my GI went in deep, my DGP IgA was persistently elevated even after a strict “Fasano” gluten-free diet.  The blood tests are good, but not perfect.

My daughter also had weak positives, but celiac was confirmed by the endoscopy. Her only outward symptom was stunted growth. It's kind of like a pregnancy test....a positive no matter how weak, is usually a positive. 🙂
