Negative Blood Test- Positive Biopsy
0

3 posts in this topic

How common is it to have a negative blood test and a positive biopsy?

My blood test was negative and my doctor (maybe with good reason) never went any further with testing and dismissed celiac. About a year or two later I found out onmy own that gluten was one of the major culprits in my GI problems, so I went gluten-free.

A year after that I had a routine visit with my doctor and she asked how my GI stuff was going and I told her it was mostly fine, except when I ate gluten. She then proceeded to tell me that she'd had multiple patients who tested negative on blood come back and tell her they found out gluten was a problem...

I wonder how many people actually go through with the biopsy even when the blood is negative??

I was really sick when I first went to a GI. My PCP kept telling me there was nothing physically wrong with me..

When I told the GI my symptoms, which were many, and severe. She said she wanted to schedule an endoscope right away, along with a stomach emptying study, and some blood tests. I had blood drawn that day and my scope about a week later.

When she did the endoscope she said I had total villi flattening, scalloping, and a mosaic pattern in my intestine instead of villi. She DXed me on the spot and gave me pics. She also did several biopsies too though.

The results of my blood tests came in a day later. It was negative for Celiac. I'm so thankful that everything was ordered at once. Some Dr.s do the blood test and if it's negative don't look any further. The blood tests are wrong 20-30% of the time.

Thanks. I was aware of the false-negatives on blood test, but wasn't sure how often people actually got the biopsy if their blood turned up negative. It's a good thing in your case (as you say) that everything was ordered all at once.

I think it's probably much more common for a doctor to not order the BX if the blood is negative...but I wonder how many people out there are celiac and don't know it. :huh:

    • Gluten ataxia...?
      I was explaining that some people have other trouble that is immune related and caused by eating gluten, but doesn't effect the gut in a noticeable way. According to the paper that I quoted there are some people which have different types of brain problems but don't have inflammation when tested by a biopsy.  The author used the term "non-Celiac gluten sensitivity" to refer to anyone who has any brain trouble that can be traced to gluten but without obvious gut inflammation.  There are a lot of different possible ways gluten can effect the brain some may not be related to the gut.  It could still be an immune system problem.  Normally "non-Celiac gluten sensitivity" refers to just a food intolerance.  Withdrawal symptoms are not normal and could be indicative of an immune system response of some sort, but I don't know for sure.

      Hi Richie I've put the above in quotes as you have described in the first and second sentence how I felt six months prior to my DX.   In my own case, in the end I concluded it was anxiety after consulting Dr Google!  It was such an alien feeling to me, I couldn't even think what it was, particularly as life was pretty good at the time.  Anxiety is a problem for a lot of celiacs prior to diagnosis, and often after glutening after going gluten-free. You mention breathlessness, this of course can be for reasons such as anaemia (again a common celiac problem, I had this prior to DX) but of course also can arise if you are anxious.   Re 'gluten free' - Flowerqueen is right, from what I have read on this forum some people really do seem to react with less than 20ppm.    But perhaps some other things to consider...  could there be something wrong with the batch you have consumed?  Might it be worth contacting the manufacturers?   That said, you could , as Flowerqueen suggests, have a problem with another ingredient, in the product or something else you consumed. In the past I have had a terrible reaction - fever, trembling, diarrhea, stomach cramps that lasted up to three hours the last three times I ate..... broccoli, of all things.    Who would have thought that possible?  I have often thought I should try it again, just to be sure it was the broccoli, as it is a 'super food' that I ought to have in my diet, that I like very much, but the thought of having such a reaction again has put me off. I do hope you will find some answers soon.

      Hi Richie,  I've not heard of this drink before, as I live in the UK, but any drink made from barley is something you should avoid.  There's a brand in the UK that makes lemon and barley water and orange and barley water and Coeliac UK say it is not safe for people with Coeliac disease.  (Our labelling laws in the UK changed a couple of years ago).  You say the drink you had was under 20 ppm, which is acceptable (usually) for coeliacs, but a lot of people are super-sensitive to gluten even in very small amounts.  I recently had a similar problem with something which was supposed to be okay for coeliacs, but when I checked the website of the product, for all it said there were no gluten containing ingredients, it was produced in an area where gluten was present, which was enough to put me off and must admit, the symptoms you describe sound very much like I experienced at the time.  (Personally I'd be avoiding that particular drink like the plague from now on). One other thing though,  have you checked the ingredients to see if there could be anything else in it which you may be intolerant to?

      Hello! I am new to this Celiac website... Is there anyone out there with Celiac AND extensive food allergies? My allergies include shellfish, dairy, eggs, cantaloupe, kiwi, mango, nuts, oranges, red dye, and more I can't think of. I went to the allergist about a year ago to see why I wasn't feeling well, and once everything was eliminated, I still didn't feel well. We did more testing to find out I had celiac as well as allergies to cattle as well as rye grass (I live on a farm basically). This was back in January 2016. I recently had my endoscopy with the gastroenterologist a week ago. I have no idea what to do or what to eat... So fish and potatoes for me!

      Week 4 of the gluten challenge- wheat cereal every morning, regular bread every day, and wheat tortillas for my lunch wraps. Right now, body aches that seem exercise related (weight lifting and running), even though I am doing the same intensity of weight lifting and running I've always done.  Just a few more weeks until my blood test. Counting down the days.
