If The Celiac Panel Shows You Don't Have The Antibody Does That Mean You Don't Have Celiac Disease?

Hi all,

I first found out I have an allegy to wheat with a IgE blood test then a nurse pract. ordered more blood tests, I think a Celiac Panel. She called me and said I don't have the antibody for celiac so I don't have the disease but now the GI doctor wants to do an endoscopy to know for sure. He told me to go off the gluten free diet, so I have. My only previous symptoms were bloating and more recently I've been experiencing muscle spasms and back pain, which did not go away even though i was on the diet for 3 weeks. I thought the endoscopy might be a good idea even if I don't have Celiac since its a camera and he might see any other problems going on? Does that make sense? Or should I be questioning whether to have this done at all?

no.

you need to find out exactly what tests were run, you need to know that the gluten free diet, even for three weeks, will affect the results of your biopsy. So, regardless of what the biopsy finds, you should consider staying gluten free as the possibility of false negative test results are highly possible. However, if you get a positive, It's positive.

back to what tests did they run. There is a specific panel of tests that must be run at minimum, to screen for Celiac.

Anti-Gliadin (AGA) IgA

Anti-Gliadin (AGA) IgG

Anti-Endomysial (EMA) IgA

Anti-Tissue Transglutaminase (tTG) IgA

Total Serum IgA

the bare minimum they should have done is the EMA and the tTG... if they didn't at least do those two tests, and show you the results, they can't tell you that you don't have it.

I had negative blood results, but the GI saw flattening in my small intestine during my endo. My biopsy was inconclusive.

I had enterolab testing and I have Gluten Sensitivity. Not full blown Celiac but I still have to follow the same diet.

no, blood tests are not conclusive. if there isn't enough damage for the antibodies produced in the gut to make it into the bloodstream, you won't get a positive blood test result.

I thought and endoscopy and biopsy are kind of the same. Isn't the procedure an endoscopy and the samples they take are the biopsy :unsure: ? I don't get it. :blink:

If the GI Dr. did an endo and he/she saw damage to the villi he/she should have taken 6-8 samples to be tested. My guess that he/she only took a few. If he/she saw damage, then most likely you have Celica.

Thanks all for the info....I'm confused though, nini, I thought you had to consume gluten before the endoscopy so it will show positive results for celiac. If I'm gluten free won't I take a risk having negative results because of the diet?

um yes, I guess I wasn't clear in my explanation... you have to be consuming gluten for the endoscope to be accurate, BUT you said you had already been gluten free for 3 weeks, SO, I was just reminding you that even if you eat a ton of gluten leading up to the endoscope, the fact that you were gluten free for 3 weeks theoretically "could" affect the test results. Realistically IF there is damage it won't go away in 3 weeks, but you never know. The human body is amazing in it's ability to heal itself and Dr.s are reluctant to dx Celiac unless they see full fledged villous atrophy.

All I was saying is if after your biopsy you are still left with inconclusive results, please consider giving the gluten free diet a good effort to see if it improves your health issues. Ultimately a positive dietary response to a gluten free diet is the best indicator.

I had a blood test (admittedly it didn't appear to do all the necessary tests) in 2001 which came back totally negative, very low results. At the time, and for at least 20 years prior to that, I had been plagued with digestive and other symptoms, including back and muscle aches and asthma type symptoms. So from that test, the doctor grandly pronounced me non-celiac. My symptoms got worse between 2001 and now, and a recent Enterolab stool test revealed a totally different picture. The test showed antibodies and auto-immune reactions, but no malabsorption (which doesn't necessarily mean there is no damage), and I have 2 genes (celiac plus gluten sensitivity). Since I have long-term ongoing symptoms, I should not eat gluten. I personally do not feel the need of undergoing the physical stress and expense of a biopsy. My doctors are relatively useless anyway, since they don't know squat about celiac disease. Even if I ignore the possible health consequences of continuing to eat gluten, the fact is, I am really sick and tired of dealing with these digestive consequences so what I need to do is obvious: stop eating gluten. Following the diet is really important for putting things into perspective.

      Accuracy of testing concerns

      By knitty kitty · Posted

      Welcome to the forum, @McKinleyWY, For a genetic test, you don't have to eat gluten, but this will only show if you have the genes necessary for the development of Celiac disease.  It will not show if you have active Celiac disease.   Eating gluten stimulates the production of antibodies against gluten which mistakenly attack our own bodies.  The antibodies are produced in the small intestines.  Three grams of gluten are enough to make you feel sick and ramp up anti-gluten antibody production and inflammation for two years afterwards.  However, TEN grams of gluten or more per day for two weeks is required to stimulate anti-gluten antibodies' production enough so that the anti-gluten antibodies move out of the intestines and into the bloodstream where they can be measured in blood tests.  This level of anti-gluten antibodies also causes measurable damage to the lining of the intestines as seen on biopsy samples taken during an endoscopy (the "gold standard" of Celiac diagnosis).   Since you have been experimenting with whole wheat bread in the past year or so, possibly getting cross contaminated in a mixed household, and your immune system is still so sensitized to gluten consumption, you may want to go ahead with the gluten challenge.   It can take two years absolutely gluten free for the immune system to quit reacting to gluten exposure.   Avoiding gluten most if the time, but then experimenting with whole wheat bread is a great way to keep your body in a state of inflammation and illness.  A diagnosis would help you stop playing Russian roulette with your and your children's health.

      Accuracy of testing concerns

      Welcome to the celiac.com community, @McKinleyWY! There currently is no testing for celiac disease that does not require you to have been consuming generous amounts of gluten (at least 10g daily, about the amount in 4-6 slices of wheat bread) for at least two weeks and, to be certain of accurate testing, longer than that. This applies to both phases of testing, the blood antibody tests and the endoscopy with biopsy.  There is the option of genetic testing to see if you have one or both of the two genes known to provide the potential to develop celiac disease. It is not really a diagnostic measure, however, as 30-40% of the general population has one or both of these genes whereas only about 1% of the general population actually develops celiac disease. But genetic testing is valuable as a rule out measure. If you don't have either of the genes, it is highly unlikely that you can have celiac disease. Having said all that, even if you don't have celiac disease you can have NCGS (Non Celiac Gluten Sensitivity) which shares many of the same symptoms as celiac disease but does not involve and autoimmune reaction that damages the lining of the small bowel as does celiac disease. Both conditions call for the complete elimination of gluten from the diet. I hope this brings some clarity to your questions.

      Accuracy of testing concerns

      Hello all, I was diagnosed at the age of 2 as being allergic to yeast.  All my life I have avoided bread and most products containing enriched flour as they  contain yeast (when making the man made vitamins to add back in to the flour).  Within the last year or so, we discovered that even whole wheat products bother me but strangely enough I can eat gluten free bread with yeast and have no reactions.  Obviously, we have come to believe the issue is gluten not yeast.  Times continues to reinforce this as we are transitioning to a gluten free home and family.  I become quite ill when I consume even the smallest amount of gluten. How will my not having consumed breads/yeast/gluten for the better part of decades impact a biopsy or blood work?  I would love to know if it is a gluten intolerance or a genetic issue for family members but unsure of the results given my history of limited gluten intake.   I appreciate the input from those who have gone before me in experience and knowledge. Thank you all!

      A little about me and my celiac disease

      By trents · Posted

      I know what you mean. When I get glutened I have severe gut cramps and throw up for 2-3 hr. and then have diarrhea for another several hours. Avoid eating out if at all possible. It is the number one source of gluten contamination for us celiacs. When you are forced to eat out at a new restaurant that you are not sure is safe, try to order things that you can be sure will not get cross contaminated like a boiled egg, baked potatos, steamed vegies, fresh fruit. Yes, I know that doesn't sound as appetizing as pizza or a burger and fries but your health is at stake. I also realize that as a 14 year old you don't have a lot of control over where you eat out because you are tagging along with others or adults are paying for it. Do you have support from your parents concerning your need to eat gluten free? Do you believe they have a good understanding of the many places gluten can show up in the food supply?
