Help With Test Results?

Back in January I got the blood test done for Celiac but wasn't able to get copies of my results until yesterday. Shortly after my blood test, I had an endoscopy. The endoscopy initially showed damage that apparently looked like Celiac but the the biopsy came back negative. About two months ago my GI doctor went ahead and put me on a gluten free diet and said that I had a positive blood test (I was told differently by my regular doctor, who was the one that ordered the tests.), all the symptoms, and that the endoscopy looked like Celiac even though the biopsy was negative. She basically told me that I had Celiac and to try the diet. So for the past 2 months or so I've been gluten free and feel somewhat better but not completely. I went to a nutritionist and she was confused because my primary doctor wrote "positive gluten intolerance" on my record while my GI apparently had Celiac written down. That left me confused so I got the results for myself and am hoping that someone on here can tell me what they mean and if I even need to be on a gluten free diet. Here they are:

Deamidated Gliadin Abs, IgA: Result: 14 Normal Range: 0-19 Normal

Deamidated Gliadin Abs, IgG: Result: 27(Abn: H) Normal Range: 0-19 Weak Positive

t- Transglutaminase(tTG) IgA: Result: 2 Normal Range: 0-3 Negative

t- Transglutaminase(tTG) IgG: Result: 4 Normal Range: 0-5 Negative

Endomysial Antibody IgA: Result: Negative

Immunoglobulin A, Qn, Serum Result: 177 Normal Range: 61-348 Negative

From what I can see, I only have one weak positive out of the whole panel. And from what I read, that's one of the least accurate tests. And I have a negative biopsy. Do I even need to be eating gluten free with these results? Do I have Celiac disease or not? Thanks for any help you can give me!

I am not an MD and I believe you need to get your medical ppl together or see a different GI doc for a second opinion. I can't speak for others who will reply, but I would not change anything until you meet with your doc and discuss what is better, what isn't and get these questions resolved. Good luck.

Thanks for replying. :)

I don't think switching doctor's will be necessary. I like my GI doctor and I'm sort of stuck with my regular doctor anyway. I've already had all the tests done and gotten results. Now I just need someone to interpret them and help me figure out if I have Celiac or not. I know that some people on here are good at interpreting test results and knowing what each test means so hopefully someone can give me an answer!

Actually, the DGP is a very specific and reliable test. It is not uncommon to have the majority of bloodwork come back negative. Antibodies are mostly in the gut, not the bloodstream.

My guess would be that you are in early stages of the disease. Celiac is patchy, and easy to miss on a biopsy. The fact that your GI saw visible damage is a big clue though. Had the disease progressed, eventually your bloodstream would become mmore saturated with antibodies.

Healing takes time. The fact that you have noticed some improvement is also telling. Many people take 6 months or more beefore they see significant improvement.

So, in answer to your question- yes, you have celiac, and yes, you do need to be on the gluten free diet for life.

Thanks for the help! I must have gotten the DGP confused with another test.. is it this one that has 99% accuracy? I read that one has 85% accuracy and I thought that was the one I tested positive in.

And just to be sure, false negatives on blood tests are extremely rare, correct? It probably sounds like I'm trying to deny that I have celiac or something and I'm not- I just want to be 100% sure that I have it. I've done pretty well with the diet for the past two months and have been lucky to only have a few rough days. I've actually enjoyed eating healthier and learning new recipes and such! Anyway, thanks again for the help! :)

The Deamidated Gliadin is actually pretty accurate. There is an older version of the test for gliadin antibodies, that is the one that's not so specific.

I think a positive DGP means celiac.

Also...the term "positive gluten intolerance" is sometimes used interchangeably with "celiac". Though you apparently didn't have the villous atrophy, you do most likely have celiac. You just haven't been badly damaged yet. Either that, or they didn't do enough biopsy samples...that happens a lot.

Do you have a copy of the biopsy report? Reading for yourself can tell you a lot more than just hearing "negative" from the doc.

Yes, you are reacting to gluten and need to be gluten-free.

Oh brother, I can see there were a lot of us here all at once, LOL. Sorry for the extraneous info! :ph34r:

I actually just read my first post and realized I made a typo. The "positive gluten intolerance" should be "possible gluten intolerance." My bad.

Also, I do not have a copy of the biopsy report. All I have is the paper they gave my parents at the hospital when I was still drugged up haha. That's the paper with pictures and the one that says they saw damage and suspected Celiac.

yes, the DGP IgG is the most specific test around, after the EMA test.

HI Abby,

RE: your question about false negatives, yes, there are false negatives. False positives are rare but false negatives are not. The antibodies to your gut (celiac antibodies) are mostly in your gut where they do their work. They aren't aimlessly floating around the blood stream, they have a job to do and they go do it. Actually most of them are created in the gut to begin with. Your gut is a front line defense mechanism in protecting you from invading microbes, and it has lots of immune cells to fight that battle. If it didn't we would be in bad shape with eating all those little ugly buglies in our food each day. The stomach has hydrochloric acid to stop some of them but it isn't enough to kill all of them. That's why probiotics work.

Here is some reading material for new people and older people too.

      Have you tried a diet with a lower carb, higher fat content, something similar to the Keto diet? Are you familiar with the ketogenic diet? Fat satisfies and so curbs hunger and levels out blood sugar.

      I've was diagnosed celiac over 10 years ago when in mid 50s. For a long time I have been getting headaches at night and in the morning and I suffer a lot of insomnia. The headaches can be very severe and sometimes develop into a full migraine but other times they wear off within an hour of getting up and eating breakfast. I have self diagnosed this a hypoglycaemia...

      But that's the point Scott is trying to make. It is up to you. You do not have to go forward with another biopsy simply because your doctor wants you to. They work for you, not the other way around.

      Honestly that's a good question, but I would like an official answer since I'm not a professional and my doctor's in my opinion no offense to them I'd say gone about it in a unprofessional way unless other's have been told to go gluten free, get a biopsy, just to go back gluten due to a possible false reading and then gotta go back for another biopsy But...

      I've was diagnosed celiac over 10 years ago when in mid 50s.  For a long time I have been getting headaches at night and in the morning and I suffer a lot of insomnia.  The headaches can be very severe and sometimes develop into a full migraine but other times they wear off within an hour of getting up and eating breakfast.  I have self diagnosed this a hypoglycaemia.  The medical profession in UK, where I live, does not seem to know anything of this and simply tests me for diabetes, which I do not have.  I know this condition is diet related and caused by carbohydrates, I avoid eating in the evenings.  Whatever I do, this condition seems to be getting worse and is very difficult to control.  Any advice would be much appreciated.
