Blood Test Preparation Advice

Hi there,

 

My doctor has recently requested a blood test for coeliac disease (sorry that's how we spelt in here in the UK!) after suffering from constant abdominal pain every day for over two weeks now. This has been coupled with other symptoms common of this disease, such as low mood/mood swings, extreme fatigue, back pain, nausea etc.

 

I have always ate a diet pretty high in gluten, including a lot of pasta and bread, but since I have been suffering from these symptoms for the past few weeks I have cut back a bit on the amount of gluten I have ate. I was just wondering would these affect the results of my blood test, or would I have antibodies present due to the amount of time I have been eating gluten.

 

Any advice would be great, thanks!!

The only recommendation I've seen is for folks doing a gluten challenge after an extended period of time of being gluten-free.  I was never a big bread and pasta person, but did consume gluten daily in other foods (e.g. soy sauce) and my bloodtest came back positive.  However, it was a "low positive".  I think it takes quite awhile for the antibodies to get out of your system, and they wouldn't go away by cutting back on gluten - only by cutting it out completely.  So in my opinion, it doesn't seem like you'd have a problem.

 

(Edit: the recommendation I referred to is to eat the equivalent of 2 pieces of bread each day.)

Thank you!

 

Was the low positive enough for them to do an endoscopy?

If you're still eating gluten, you'll probably be okay to test. 

I was never a huge gluten consumer even before I was diagnosed and my labs were still positive.

Yes.  The lab that did my bloodtest considered anything over 11 as a positive.  I was at 13.  They did the biopsy and found moderate to severe villi damage.  So I have no faith in the "weak positive" thing.  As far as I'm concerned... positive is positive.

I agree. I think of it like a pregnancy test... There's no such thing as a little bit pregnant. There's no such thing as a little bit celiac - just the severity of our symptoms may vary.

Thanks for the input everyone, I feel a little more confident now that this test won't be a waste of time. In fact as crazy as it sounds I somewhat hope it comes back positive, as it seems the only other diagnosis they are willing to give me is IBS and at least with coeliac disease there is a treatment, as opposed to being told sorry there's not much you can do!

      Get tested for vitamin deficiencies. Though neuropathy can be a symptom of celiac, it can also be caused by deficiencies due to poor digestion caused by celiac and could be easier to treat.

      If you're just starting out in being gluten free, I would expect it to take months before you learned enough about hidden sources of gluten before you stopped making major mistakes. Ice cream? Not safe unless they say it is gluten free. Spaghetti sauce? Not safe unless is says gluten-free. Natural ingredients? Who knows what's in there. You pretty much...

      We feel your pain. It took me 20+ years of regularly going to doctors desperate for answers only to be told there was nothing wrong with me … when I was 20 pounds underweight, suffering from severe nutritional deficiencies, and in a great deal of pain. I had to figure it out for myself. If you're in the U.S., not having an official diagnosis does mean you can't claim a tax deduction for the extra expense of gluten-free foods. But it can also be a good thing. Pre-existing conditions might be a reason why a health insurance company might reject your application or charge you more money. No official diagnosis means you don't have a pre-existing condition. I really hope you don't live in the U.S. and don't have these challenges. Do you need an official diagnosis for a specific reason? Else, I wouldn't worry about it. As long as you're diligent in remaining gluten free, your body should be healing as much as possible so there isn't much else you could do anyway. And there are plenty of us out here who never got that official diagnosis because we couldn't eat enough gluten to get tested. Now that the IL-2 test is available, I suppose I could take it, but I don't feel the need. Someone else not believing me really isn't my problem as long as I can stay in control of my own food.

      If you're just starting out in being gluten free, I would expect it to take months before you learned enough about hidden sources of gluten before you stopped making major mistakes. Ice cream? Not safe unless they say it is gluten free. Spaghetti sauce? Not safe unless is says gluten-free. Natural ingredients? Who knows what's in there. You pretty much need to cook with whole ingredients yourself to avoid it completely. Most gluten-free products should be safe, but while you're in the hypersensitive phase right after going gluten free, you may notice that when something like a microwave meal seems to not be gluten-free … then you find out that it is produced in a shared facility where it can become contaminated. My reactions were much-more severe after going gluten free. The analogy that I use is that you had a whole army of soldiers waiting for some gluten to attack, and now that you took away their target, when the stragglers from the gluten army accidentally wander onto the battlefield, you still have your entire army going out and attacking them. Expect it to take two years before all of the training facilities that were producing your soldiers have fallen into disrepair and are no longer producing soldiers. But that is two years after you stop accidentally glutening yourself. Every time you do eat gluten, another training facility can be built and more soldiers will be waiting to attack. Good luck figuring things out.
