How Long To Wait Before Testing?
0

4 posts in this topic

I only went gluten free for 12 days and then started eating gluten again thinking I wasn't noticing that much of a difference.  I was focusing so much on my joint pain that I didn't realize that my headaches, nausea and heartburn had gone away.  Within 12 hours of re-introducing gluten I had heartburn and liquid diarrhea.  My doctor agreed that we could do blood work for celiac disease if I want. 

 

Do I really need to eat gluten for 6 months before I can get tested even though I was only off for 12 days? 

 

How long should I wait before having the tests ordered?

 

What specific tests should be ordered?

You definietly have some sort of gluten intolerance... it's nice when those migraines slip away isn't it?  :D

 

Since you were only gluten-free for 12 days, you could probably accurately test within a couple of weeks. I would guess that somewhere around mid to late May would give you accurate test results; sooner might be fine but there's no way to tell.

 

The tests most often given are;

 

  • tTG (anti-tissue transglutiminase) IgA and IgG
  • DGP (deaminated gliadin peptide) IgA and IgG
  • EMA (anti-endomysial antibodies) IgA
  • total serum IgA (control test)
  • AGA (anti-gliadin antibodies) IgA and IgG (older test)

The first test seems to be the most popular with doctors, the DGP tests are newer and often pick up early celiac disease a bit better, the EMA is positive when the villi damage is extensive and the serum IgA is to make sure you make enough IgA so your tests are accurate (5% of celiacs are deficient in IgA).

 

I hope your time eating gluten isn't too bad. Enjoy a cinnamon bun or a beer for me.  ;)

Welcome!

 

I agree with Nicole.

 

Some have found it a bit easier to eat gluten late in the day/early evening during challenge -- and no need to overdo it -- a slice or two of gluten containing bread per day is plenty according to many of the top celiac centers.

 

Hang in there and let us know if you have more questions :)

 

Edited to add nutrient/misc testing as malabsorption is an indication of celiac disease:

 

B1, B2, B6, B12, D, K, Iron, Ferritin, Copper and Zinc

Complete Metabolic Panel (CMP)

Complete Blood Count (CBC

Thank you for the replies.  I've e-mailed my doctor to see if I can have the testing done later in May.  I'm finding it really strange that I didn't realize how lousy I usually feel until I was actually feeling better.  This might be a long few weeks but I will try to enjoy some tasty treats for everyone here without making myself too sick.

    • What would be helpful, Victoria, is to have a full thyroid panel done because you cannot diagnose anyone with Hashi's without a full panel.  It is more important to see what the actual hormone levels are than the TSH. Those would be Free T3 and T4.  You can have low hormone levels and normal TSH.  Your TSH is not too bad but if it starts to climb any higher, that would be cause for concern for Hashi's.  At least your lab seems to use the newer ranges for testing.  Many labs use outdated ranges that go to 5.00 for a cutoff. When my TSH was a 7, I could barely drag myself out of bed in the morning. I have Hashi's and your symptoms are a laundry list for it and Hashi's is very common with Celiac Disease.  You can start having Hashi's symptoms long before the blood work goes off.......like Celiac.
    • With the 3 positives that you have, Jenna, you have Celiac Disease. Positive tTg and EMA is a slam dunk. At this point, if you do the biopsy, you don't need it for diagnosis.  It will be to check for extent of damage.  Considering your health issues, it's pretty apparent you have a gluten problem anyway. Congratulations on figuring out your problem.  Now you can sit back and watch how amazing it will be when many of your problems resolve or improve dramatically. I had the same positives you did and declined the biopsy. 3 years after I was diagnosed, all my symptoms were gone but I do have other AI issues which are not, but they are much, much better just from going gluten free.  Be optimistic this will happen for you also!
    • I'm not sure what you mean by score, but her testing at the Mayo Clinic looks like what they describe in the Mayo Clinic link I included.  The posted results are in reverse order of the actual testing. Testing started with total IgA (for some strange reason labeled "Celiac disease, cascade" and does not include units).  It was within the normal range listed in the Mayo link under "Reference Testing" so testing continued with TTG IgA.  Jenna3, the total IgA is to ensure that the results of the rest of the IgA  tests are valid.  It is looking at total IgA antibody, not celiac antibodies. TTG IgA was a weak positive so testing continued with EMA IgA and Gliadin IgA which per the Mayo website is the deamidated gliadin peptides.  It looks like there should be an EMA titer reported. Hope this helps.
    • I second the request for a falafel recipe!
    • So I was googling my symptoms I still have after being gluten-free for 9 years and came up with Hashi's.   symptoms chronic c, even with extra magnesium citrate feeling tired all the time, despite using cpap for sleep apnea very succesfully  muscle weakness and joint stiffness, my lower back hurts so bad every day Hair loss memory lapses (getting worse) Dry skin im freaking cold all the time. Ac is killing me this summer.  High cholesterol, the bad one (been bad my whole life) Depression and low motivation to do lots of simple life tasks tendency towards anemia (my annual physical didn't check so I don't know current value) my TSH is 2.590 uIU/mL    0.600-3.300 uIU/mL   Is there anything I can do at home to help these things? Should I share this with my doctor? I have a new one who doesn't know me well at all. What do I say? thanks for any advice and feel free to ask questions!
