Should I Take Another Test?
0

5 posts in this topic

For the last few years I've noticed that I've been having digestion and stomach issues. It seems to have gotten worse in the past few months. When someone suggested it might be a gluten allergy, I decided to go to my doctor for a blood test. Prior to the test, I started trying to eat more gluten free foods. I wasn't completely off gluten, but I was trying to switch some foods, like bread and cereal, for gluten free brands. After about 5 days of this diet, I got in for an appointment and a blood test. I just found out the results of the blood test: apparently I was just in the "normal range" for not having an allergy to gluten. My doctor thinks I should eat regular foods (with gluten in them) and come back in 4 weeks to get the test again. I'm pretty sure I have some kind of sensitivity to gluten just from how much better I feel when I'm not eating gluten foods, and don't want to have to suffer through another 4 weeks of eating gluten just to see if this test will come up positive. Do you think I should try the test again (and feel sick from eating the gluten for 4 weeks?) or should I ask for a referral to a GI doctor instead? Thanks for your help!

Are you saying you were only off most gluten for 5 days? If so, that's not long enough to change test results so your test was valid. You could still be gluten intolerant. There is no test other than trying the diet.

I'm also confused about what test you got. Did you get celiac testing or wheat allergy testing? They are not the same. Be sure it was celiac testing and that you got the full celiac panel before you went off gluten. Read this from the University of Chicago Celiac Center that explains the tests.

I agree. 5 days wasn't long enough to make an impact especially since you said you weren't even totally gluten free. The AGA is a good test for gluten intolerance.

It was an Anti-gliadin test, and the nurse said my number was 11 (Can anyone explain this?). Unfortunately, she didn't explain what that meant, but said that I tested negative. I told her that I just wanted a referral to a GI specialist, so that is the route I think I will go. Thanks for your help.

We can't tell you what the number means without the "normal" range from that laboratory.

Anti-gliadin is NOT a full celiac panel and it's the least reliable of the celiac tests. Keep eating gluten until you get to a GI or get your GP to run the full celiac panel. There are other tests that need to be run, a test for your total IgA, anti-TTG, and anti-DGP.

    • Below is copied & pasted from this thread:   My celiac doctor is Dr. Syed Jafri, in Webster, TX (just south of Houston -- basically the Clear Lake City area), saved my LIFE.  I would recommend him to the whole, entire world.  I was desperately ill, and am still struggling, and he's a wonderful, sweet man who listens and is very proactive in helping you solve whatever problems you're having.  I wish all doctors were like him.  I have to fight and struggle with too many doctors to just listen to me and what I live with, day in and day out.  He's not like that.  Good luck to you.     There are recommendations on this thread too:  
    • I never worried about cross contamination because i was originally told i was just intolerant. after going gluten free i felt so much better up until this last march. dairy and fructose have been giving me problems but both lactose and fructose test came back negative.  this is what my gi doctor emailed me today 
    • Any place you know of to find more info? Seems like I am still in so much pain/bloat, I am not even sure if I would pick the right 5 foods!
    • Don't freak out worrying about other maladies yet. You would be absolutely amazed at the things that can/will resolve on the gluten free diet. Some take longer than others -- neurological seem to take the longest for most people but really, I guarantee, there will be things you had no idea or expectation of resolving will. There were tons for me and then there were things I sort of "woke up one day" & said, "hey, that's gone and that & that & that". Other, larger things had taken my attention so I hadn't paid attention to the smaller things until...... On the other hand, not everything is related to celiac but I bet you wouldn't find a handful of celiacs who didn't say something very similar to what I said above. Yes, thyroid problems are common with celiac but I'll also tell you there are/have been people on here who were hypothyroid before dx but after being gluten-free for a while they actually went back to normal thyroid numbers. My husband is one (yes, we both are celiac - it happens). He was on synthroid for 20 years or more. Guess what? He's not on it anymore. We've had his thyroid panel done several times since about a year gluten-free & he is no longer hypothyroid. 
    • Yes please, that'd be awesome Having a fun time trying to reply on my phone due to broken screen but will be back on tomorrow after results of doctor appointment to get to the bottom of why they've given me seemingly wrong advice re: next steps. Yup I'll admit to pity, anger, frustration and outright fear, been through the mill of emotions in this first week that's for sure. One thing before I go for that; back when I was self-diagnosing I wanted a full thyroid panel (T3, T4 etc.) and also ESR & CRP checks for vasculitis and similar maladies. Now it seems from my reading they can often follow celiac so my worry level of those has gone up a notch, more blood tests ahoy it seems? Main reason for worrying about those is the nearly constant tight / tender head I have at the moment. Top and sides of scalp. Could be the stress tensing the shoulders and occipital muscles at back of head but after the celiac diagnosis being missed I'm fearful of anything else being missed. Did anyone else have this tight head feeling at the start? Feels like the skin is being pulled inwards, sometimes goes down for a few minutes here and there and gets worse when sitting I think. I see the term "brain fog" a lot but luckily don't seem to have too much of that at present, this is more a physical sensation.
