Negative blood test but still concerned!

Hi all,

Back in September, I had stomach issues for a few weeks. My doctor said it was a virus but ordered me a blood test for Coeliac Disease as my sister has the condition. My results came back as:

Tissue Transglutaminase Antibodies (tTG-IgA) : 4.9 (5.00 - 20.00) 

Doctor said nothing to worry about. However I still have periods where I have gas and soft stools (not diahoerra). Also, my sleeping pattern has been a mess since September and I've had mouth ulcers at least twice since then too. Is it worth going back and asking for a biopsy? 

Thank you all in advance!

Before asking for a biopsy, you might ask for a complete celiac blood panel:

-Tissue Transglutaminase (tTG) IgA and (tTG) IgG
-Deamidated Gliadin Peptide (DGP) IgA and (DGP) IgG
-EMA IgA 
-total serum IgA and IgG (control test)
-AGA IGA and AGA IgG - older and less reliable tests largely replace by the DGP tests
 
-endoscopic biopsy - make sure at least 6 samples are taken
 
VERY IMPORTANT:  Keep eating gluten daily until ALL testing is complete or the tests can be inaccurate.  
 
(Source: NVSMOM -- ?)
 
Why the full panel?  The TTG does not catch everyone.   My TTG tests are always negative (even in follow-up testing).  I was positive on only the DGP IGA.  Go figure!  How did your sister test?  

 

Welcome to the forum and let us know how it goes!

I tested Negative in August on the celiac panel. My symptoms continued and I had to go back to my doctor for a follow up on my anemia.  She referred me to a GI doctor because my numbers didn't improve.  The GI doctor felt that I didn't have celiac, but she ran the genetic test to be thorough and so that we could confidently eliminate it from the list of potential diagnoses.  The genetic test  came back positive.  Since I'm having symptoms I'm getting an EGD with biopsies in a couple of weeks.  The doctor said that she rarely sees people test negative on the panel and have celiac, but it does happen, and there's no explanation to why it happens because our bodies are complex.

My take on your situation; if you aren't confident that celiac isn't your problem and you haven't exhausted all testing options, then keep going.  You only get one body and one life and nobody is going to advocate for you as well as you.

Hi, thank you for your reply. I plan on going back for peace of mind. Can you describe your continuing symptoms after your blood test please?

      Yes, I, too, have osteoporosis from years of malabsorption, too.  Thiamine and magnesium are what keep the calcium in place in the bones.  If one is low in magnesium, boron, selenium, zinc, copper, and other trace minerals, ones bone heath can suffer.  We need more than just calcium and Vitamin D for strong bones.  Riboflavin B 2, Folate B 9 and Pyridoxine B 6 also contribute to bone formation and strength.   Have you had your thyroid checked?  The thyroid is important to bone health as well.  The thyroid uses lots of thiamine, so a poorly functioning thyroid will affect bone heath.

      That sounds so very likely in my case! I will absolutely ask my doctor on my next bone check coming up in March... Thanks a lot!

      Calcium levels as measured in the blood can be quite deceiving as the body will rob calcium from the bones to meet demands for it by other bodily functions. Also, supplementing with calcium can be counterproductive as it tends to raise gut pH and decrease absorption. More often than not, the problem is poor absorption to begin with rather than deficiency of intake amounts in the diet. Calcium needs an acidic environment to be absorbed. This is why so many people on PPIs develop osteoporosis. The PPIs raise gut pH. And some people have high gut PH for other reasons. Low pH equates to a more acidic environment whereas high pH equates to a more basic (less acidic) environment.

      Kind thanks for all this valuable information! Since my Folate was/is low and also my Calcium, there IS a chance I am low in B vitamins... My doctor only measured the first two, oh and Zinc as I has twisted her arm and guess what, that was mega low too. So who knows, until I get myself tested properly, what else I am deficient in... I did a hair mineral test recently and it said to avoid All sources of Calcium. But this is confusing for me as my Ca is so low and I have osteoporosis because of this. It is my Adjusted Ca that is on the higher side and shouldn't be. So am not sure why the mineral test showed high Ca (well, it was medium in the test but relative to my lowish Magnesium, also via hair sample, it was high I was told). But anyway, thanks again for the VitB download, I will look into this most certainly!

      Allergy medication: cetirizine by the HealthA2Z is it gluten free?

      By ElisaAllergiesgluten · Posted

      Hello good afternoon, I was wondering if anyone has ever brought their anti-allergy pills? I have been wanting to use their Cetirizine HCI 10mg. They are called HealthA2Z and distributed by Allegiant Health.I’m also Asthmatic and these allergies are terrible for me but I also want to be sure they don’t have any sort of gluten compound.    I have tried calling them but to no avail. Has anyone ever used them? If so, did you had any problems or no problems at all?    thank you
