Those Of You Who Know About Blood Tests....

Well, this is kind of interesting. I found an old blood test from 2001....at that time I had requested a celiac test from my GP, who really knew nothing about celiac disease. Anyhow, I just found the old results....at the time I didn't realize this paper was the celiac test because it doesn't say that, but with my new-found knowedge I realize that's what it was. Here goes:

Antigliadin AB, gliadin AB IGG: 3 where less than 20 is called "normal."

Gliadin AB IGA was 2.

DO THESE SOUND LIKE THE RIGHT TESTS?

How about 'them apples! Of course, the doctor said "Your test was negative."

So 5 more years of digestive hell for me!

Yet in January 2006 Enterolab rates me like this based on a stool sample:

Fecal Antigliadin IgA: 24 (normal is <10)

Fecal Antitissue Transglutaminase IgA 19 (normal is <10)

Microscopic Fecal Fat Score 67 (normal is <300)

HLA-DQ Gene DQB1 0201, 0604

Fecal Anti-casein IgA antibody 22 (normal <10).

Now I was having all sorts of problems back in 2001 when I requested the celiac blood panel. While I was eating gluten, I have always minimized what I ate. For whatever reason, not much showed up in my blood, yet I was having symptoms. Kind of strange. But my current fecal fat score was low, which indicates no malabsorption to speak of, so could that be why nothing showed up in my blood test???

I think the lesson in all this is that the blood test doesn't tell the whole story.

No wonder no one knows quite what to do with all this, and how to interpret things. After my "negative" blood test I was really looking to other possibilities to explain my digestive woes. But you know, my incredibly sensitive celiac mom would have a negative blood test now too. Maybe a lot of it has to do with how much gluten you eat. Although I ate gluten things, I have really minimized what I ate for many years. I didn't eat it every day.

I dunno....what do you more knowledgeable folks think about all this? :o

those tests are only a partial celiac panel... doesn't look like the complete panel, they only did the Anti Gliadins and those are not even in teh bare minimum that they would have needed to do to determine if Celiac was a possibility.

Anti-Gliadin (AGA) IgA

Anti-Gliadin (AGA) IgG

Anti-Endomysial (EMA) IgA

Anti-Tissue Transglutaminase (tTG) IgA

Total Serum IgA

here is the complete panel... They would have to do at minimum the EMA, tTG and, total serum IgA to get a more accurate picture... plus the AGA's...

As the Celiac Specialist that spoke at our meeting said though, many people can have negative test results and still have damaged villi...

the blood tests are only part of the picture. Ultimately the dietary response is your best indicator. How does your body react to gluten? Doesn't like it? Then stay off it. Period. It's that simple.

This incomplete blood test just shows how utterly CLUELESS most doctors are. At the time I requested the test, I was having a lot of digestive and OTHER symptoms, and I told my doctor about wanting to get tested, and he was of course totally ignorant about what test to order. And he was also a bit reluctant to order the test because, after all, I didn't fit the classic profile. Anyhow, I would say to anyone who is thinking of getting testing, make sure all your ducks are in a row before you go to the expense of blood tests!

My husband was finally dx at aged 40.

He too had a neg result on the bloods,but a biopsy showed positive.

He has alway's been very thin,and (for as long as I've known him-20yrs!)hardly ever ate any sizeable amount.

By the time of diagnosis he could only manage a few mouthfuls(he was very ill),so hardly suprising he got a negative!

Hi Nikki...I see you are in the UK. I thought doctors in Europe were better at diagnosing celiac than they are here. Am I wrong? Is it just as tough to get a real diagnoses there too???

It varies hugely from country to country in Europe, and it also depends on who you happens to see, of course.

      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

      By trents · Posted

      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?
