Just wondered if anyone knows if it is possible to have a false positive blood test?

My GP tested me positive for coeliac, but when i saw a specialist to arrange a biopsy he said he doesnt think it is coeliac.

he said it may have been a bug i caught while i was travelling in indonesia 2 years ago...he also said i am too healthy to be coeliac...

anyone else experience this kind of thing? or know about false positive blood tests?

thanks :huh:

Is your doctor going to do the biopsy anyway? They should. They can't rule out Celiac on the appearance of good health. They cannot see the damage in your intestines by just looking at your outward health. Some people are completely symptom free, but their intestines are completely damaged.

If your blood test was positive, then you either have Celiac Disease (advanced stage of gluten intolerance), or you are gluten intolerant. In my opinion there are no false positive blood test results, only uninformed doctors. Please either get a new doctor or pursue it further with this one. Insist on the biopsy, and if that fails then try the diet anyhow. If you feel better off gluten then that should be the proof that gluten is your problem.

God bless,

I agree, with it not being possible to have a false negative test. Everything I have read says, it is not possible. A positive blood test may not mean you have damage to the villi (yet) but it does mean that you are reacting to gluten. It's ridiculous for a doctor to say that someone looks 'too healthy' to have a problem ! I would look on this site for a referral to find a new gastroenterologist. There are a lot of problems not normally linked to celiac disease or gluten intolerance that many drs are ignotrant of. Just because you don't appear to have the 'classic' problems does not mean you are not reacing to gluten.


If you are gluten sensitive, then it is important to follow a gluten free diet, in order for you not to develop celiac disease.

It is possible to have a false negative blood test(s), like my son did. He had over 70% of his small intestines, part of his ileocecal valve and part of his colon removed at 6 days old. His symptoms from short gut were similar to celiac disease, and he had been tested for it several times and had false negative results. Since he has gone gluten free after a biopsy showed celiac disease, he has made HUGE STRIDES and is gaining weight wonderfully :D

I have always been curious, too, about the possibilty of a false positive, since my blood and biopsy were very positive yet I have had little improvement on this diet. I've been gluten-free for 8 months and am still showing positive antibodies that have not dropped at all. It is so discouraging I can't even tell you. It makes me think I have something else instead that can't be resolved through diet. I am assuming, though, that a positive IgA and Ttg can't be wrong, especially since I have serious damage to my villi. I'm just still wondering if some other disease could have done that. :unsure:

thanks all for the help and advice,

my doctor is being reasonable about it - he has not ruled out coeliac and will do the biopsy to check - but he is going to do lots of other tests as well because he is convinced it is something i picked up while travelling. what he is saying makes sense and i did get very sick while in Bali, but having had the positive blood test it just doesnt add up :(

i know that my body doesnt like food - its not just gluten though, my system doesnt like anything in it. i have to not eat at all to feel well :angry: the doctor said i have too many of the bacteria (that we all need a little of) in my gut and so when i eat, it over reacts and makes too much air - or something like that...

did anyone else find that before they went gluten-free all foods upset them or just foods containing gluten?

thanks for the link to recommended doctors, but i am in England ;) bit far to travel really - lol :P

If your reacting to gluten, you will most likely react to any foods, unless you avoid gluten long enough that you are able to heal, then you may notice that one food is ok, and another is not. Until going gluten-free I had diarreah all the time, every day no matter what I ate. I couldn't even finish a meal without running to the bathroom. There was no way to determine at that time it was a gluten containing meal or not.

    • I would say no even then....it belongs in its own little corner in hell. We have had members get sick from cross contact touching and handling paper mache, playdough, and dry wall spackle containing wheat then touching their mouths, or food.....heck you can inhale the powder from the sanding spackle and have it get trapped in the mucus in you respiratory tract to run down your stomach and make you sick......has happened to a few on many occasions.
    • Cross reactivity is a bit of a myth type thing, but we do get food sensitivities and intolerance issues that do creep up and they are always different for each person. A food diary and keeping track of what causes symptoms is what you need to do. Here is a true gluten avoidance list and a article on food sensitivities.
    • Me too. I still get transient lower back pain occasionally when my bladder or colon is full. It goes away immediately on voiding. Regardless of anything other diseases you may have, being wheat free gives you relief so even if not Celiac you are Non Celiac Wheat Sensitive. There are over 200 symptoms that are improved with GFD gluten free diet. Google it. It is an impressive list. In any case, while it is good to have a diagnosis, there is only one treatment, do not eat wheat and deal with the inevitable malnutrition damage.(think Biafra babies 1970.) Most will improve over time. Whatever doesn't improve should be investigated to be safe, but realize that recovery may take years. Wheat flour used should be limited to Paper Mache sculpture and library paste.  
    • Here is a partial list of what I no longer suffer from as a result of not eating wheat. Some like the sleep apnea and gerd and back pain and addiction to alcohol were almost immediate. The foot pain is improved to just numbness sometimes. My long term depression went away when I added vitamin D 10,000 iu a day for a year, but the improvement started almost immediately. Muscle tone and energy improved when I added iodine. one sheet sushi seaweed a day. My Fibromyalgia is controlled with 15 mg oral Prednisone a day. I remember as a kid waking up and having to pick the dried mucuos off the roof of my mouth. That is gone and for the first time in my life I am a nose breather. Drink lots of water to help with the mucous if it is thick. Some mornings mine is like rubber cement. I need to quit smoking now.  You can improve have faith, but healing takes time. Stay the course. A Romaine lettuce salad everyday helped the gut pain. Gerd shortness of breath sleep apnea back pain snoring prostrate hypertrophy contact lens protein buildup night vision improved cataracts reduced head hair growth foot pain sleeping no more than 2 hours at a stretch slow healing no energy. Pretty much bed ridden. 
    • Celiac Disease is damage to the nooks and crannies in our intestines leading to malnutrition, vitamin deficiencies with all the various symptoms that make it so hard to diagnose. Then you add years of the antacids, antibiotics, Tylenol, opioids, alcohol, etc., each with their own particular side effects and damage. Now you've got a toxic environment that kills off the beneficial bacteria increasing malnutrition. Theoretically you can eat anything except gluten. But wheat is so ubiquitous in our diet and economy there are unlimited opportunities for cross contamination. So read the label. Use common sense. If there isn't a label it doesn't have wheat so you can eat. Big Food likes to add wheat to everything because it is addictive and helps them ensure you can't eat just one. Why on earth else would Campbells Tomato Soup have wheat listed as an ingredient? Meantime your body is in distress from malnutrition so you need to be sure to replenish D3, and Iodine for starters and treat and support any other symptoms while you heal. Good nutrition without wheat is the only way to stop progression. And just like chewing paint chips made with lead is bad, so is food with wheat.   well said, doesn't need a label.
