Negative Bloodwork

5 posts in this topic

So after almost two weeks of waiting I finally got my results back.

Turns out they only did the screening for TTG Iga!

Here is what the report says:

Tissue Transgluaminase Iga 1.1 kU/L Ref. Range 0.0 - 20.0

Immunoglobulin A 1.78 g/L Ref. Range 0.60 - 4.20

I saw a Resident as my family doctor was away. He said I did not have Celiac Disease. I asked him if I was not supposed to have more tests done and he said no, this was the only one needed. I know there are more tests to be done but if he says no, what do I do now? I think the lab only runs the other tests if the TTG Iga is higher.

The test screening info section on this site is down for maintenance so I could not look anything up.

Thanks in advance for your input.

Oh wow. I fully expected to to have a positive test; I'm really surprised that your ttg Iga didn't come back positive after that positive Biocard ttg Iga home test you did a couple of weeks ago. :huh: I don't know how one test can be positive one week and then the next week, when it's done by a different lab, it's negative...Unless celiac can flare like the other autoimmune diseases and you've entered a time when gluten isn't bothering your body as much...

Did the resident have any opinion about the Biocard test and the the discrepency beteen the two results? Now you're stuck with figuring out which test to believe. :( No fun.

When my tests were done by CLS, they ran the EMA as well, but my ttg Iga result was rather high... I have no idea if that lab runs ttg IgG tests or the deaminated gliadin peptide tests (DGP IgG and DPG IgA). It could be worth checking into.

(Hugs) to you. I know how much you were hoping for a clear result and not more confusion. I do hope you'll still consider going gluten-free for a few months (once you are sure all of your testing is complete) to see if that helps you. With that positive home test, I think celiac could be a factor in the health issues you've had and a trial of a few months might help.

I wish I could be of more help. I imagine you must be pretty frustrated, so I wish I knew more about the testing and why your results came out this way. Pm me if you need to vent. Best wishes.

I typed a long reply but it does not seem to be here?!

So, to make a long story short;

I emailed 2gpharmas to inquire about my results. They have now sent my questions to the manufacturer. I will let you know what they say.

The resident did not have much to say and had never heard of the home test. He only said that the test I had was all that was needed.

I too thought I would have a positive result. Very frustrating indeed!

I am not sure what my next step is. I am considering visiting a Naturopathic dr. and see what she has to stay. The initial visit is an hour so we should be able to cover a lot.

My quest continues...

Hello again,

I just looked up the Celiac tests on the lab website and this is what it says:

"Initial test of Celiac Disease Screen includes TTG and IgA. Additional reflexive assays will be ordered as required and may include Anti-Endomysial Antibodies (AENDAB) and TTG IgG. "

I guess since my TTG Iga was normal they did not go ahead with the other tests. Does this make sense? I thought if you tested negative for one test you could still test positive for other tests. Am I wrong?

Thanks again.

I curious what 2G Pharma will say. I would assume they'll stand by their product. :huh: I know it worked for me... you would think it would only show the line when it's reacting with the ttg IgA...

A homeopath or naturopath might be a good idea. They can work wonders for people. I have one good friend who had an autoimmune nerve problem on her face which caused her eye to slouch shut. She was on prednisone for decades and it barely helped, and then she started with a homeopath who started her on the right remedies and completely cleaned up her diet (good foods, very limited additives, and lots of organics), and it's been in remission for years. It she feels it acting up, she takes her remedy and tweaks her diet... As we know , diet can really affect your health.

And yes, you are right. You can test positive for some tests and negative for others. As far as I know, EMA is considered a good test for celiacs because it indicates ongoing significant damage is being down to the small intestine; ttg iga shows damage has been done to the small intestine and can be caused by milk or casein allergies or severe gastrointestinal illnesses. Together those two are pretty definitive. I don't know about the DGP tests or IgG because I didn't have them done, nor were they offered to me; I didn't look them up. I would request those tests but I have no idea if CLS does them. You might want to check those Enterolabs mail order tests if you can't get them here.

It is possible that you are gluten intolerant and don't have the intestinal damage happening. All the same symptoms like nuerological, intestinal and hair loss can occur in that group too. These symptoms are not just a result of gut damage or of nutrient malabsorption. For example, I am a celiac, but my nutrient and vitamin levels were almost all perfect but I still had thin hair and migraines (and other symptoms).

What my ramblings mean is that your diet could be causing the problems, but you may not end up being a diagnosable celiac. Tweaking your diet, for a few months at a time so you can be sure of results, may be a good next step when you are sure you are not testing anymore.

(hugs) to you. I hope that someone else can offer you good advice. Hang in there.

    • turkey
      Turkey is gluten-free as long as it is not stuffed. You can make a good gluten-free stuffing using gluten-free bread. Dry the bread first and add what ever spices or veggies you wish, but cook it in a separate baking dish because stuffing the bird with it can cause bacteria to breed. And gravy must be thickened with corn starch or potato starch instead of wheat flour.

      so you can't even cook without stuffing inside turkey and not get gluten? Sorry I'm not familiar with turkey and wondering if I can have it while rest of family gets stuffing? In other words is turkey gluten free?
    • Numbness, Tingling in limbs & Joint Aches
      Hi Ender, Although you didn't get a complete thyroid panel, from what I see you are hypothyroid.  Most Dr's only care about TSH and yes yours is in the range, but when mine is that high I get terrible joint aches.  I feel best with mine around 1.  Your free T4 isn't just a tad low...most people feel best with it around 50% of the range.  I think you could benefit from some thyroid replacement medication.  You should also get a full thyroid addition to what you've had done a free T3, TPOAB and TgAb.   The last 2 are antibody tests.  Hashimotos is found fairly frequently with celiac.   Low vitamin D can also cause aches.  It would be really good to have your levels checked again.  Until you are healed you may not absorb it well enough so it's good to keep supplementing.  It took me a year and a half gluten free to get mine to an acceptable level for my Dr and he's keeping me on 2000 daily for maintenence.  For the numbness and tingling my Dr had me add magnesium as I was having horrible tingling in my feet and my B12 was good.  I have to say it has helped a lot. I hope you are able to get this figured out...I would definitely start with a complete thyroid panel and recheck of Vitamin D.  Here's a bit of reading on thyroid stuff if you have time.  Hugs!
    • Positive & Increasing TTG -- questions re: testing & history
      I'm a 31-year-old high school teacher (currently on disability) who has been dealing with 4 years of major gastrointestinal problems, which resulted in major surgery for a rectal prolapse & redundant colon last August, prior to which I had lost about 20 pounds. The source of all my gas, bloating, distention & diarrhea has remained basically unexplained though ("lets trust the surgery resolves your obstructed defecation and in turn your gas... d'oh it made both  worse"  ) , and my symptoms have only gotten significantly more severe since surgery. I'm facing a permanent ostomy. I've also, for the first time in a lonnng time, been eating a lot of gluten every day... primarily out of depression and (misguided?) attempts to gain weight and keep stool soft. I've been typically slightly underweight for 10+ years. Suffered anorexia for a period 10 years ago, and since recovering have "naturally" maintained a low weight and low-wheat lifestyle (I've always been put off by heavy wheat items like bread, sandwiches & pasta, *shrug*). As a child I had crazy severe & unexplained constipation issues. I've also had strong teeth discoloration & marked enamel defects (& two missing adult teeth(?)) since childhood. Depression & anxiety have been longterm issues. I have osteoperosis, which was perviously explained by me being anorexic from 19-22. Everything changed 4 years ago upon the onset of all my (severe) classic-IBS symptoms (gas/bloat/d+c). On a low-gluten diet, TTG bloodwork came back "low-positive" repeatedly. A biopsy showed no damage, but my gluten intake at the time was limited to 2 cookies a day, or occasionally 2 cookies and a piece of pizza. Would this have been enough to show damage? I trialled going gluten-free for a few months, and didn't find a ton of relief... so assumed I was just FODMAP intolerant... however I was eating lots of oats and lactose that whole time, which I have subsequently identified as major triggers... not to mention just lots of gluten-free junk food. Wheat was obviously a significant gas trigger since this hit, but that seems typical for gut illness in general. Since my major surgery and the continuation and worsening of symptoms, I've connected with an internist who has again and again pushed me towards eating wheat as a method towards weight gain and healthy non-anxious eating. I also found that a high-wheat diet would provide the proper consistency (i.e. very loose diarrhea every day) to allow colorectal function (the surgery I had went very poorly and caused major obstructed defecation). I have not had success gaining weight, and have found my digestive system feeling assaulted like never before 24/7 by bloating, gas and discomfort, despite a relatively low-residue diet and constant elimination. My appetite has never ever been worse. I just had a fourth TTG test, and after this high-gluten diet I am now testing POSITIVE as opposed to BORDERLINE. Questions: 1) I suspect my first biopsy's gluten challenge wasn't quite heavy enough in terms of gluten content (couple cookies a day). Thoughts? 2) Could being underweight alone cause an elevated TTG? How about simply having colorectal surgery? "IBS" or the supposedly non-pathogenic gut bacteria blastocystis hominis which I've been diagnosed with? I haven't been diagnosed with any other autoimmune condition, and I'm so confused. So far everyones just shoving the TTG off on IBS/anorexia, which doesn't make sense to me at all. 3) I really don't know what to do right now. I'm 20 pounds underweight, in digestive hell, with most of my medical support still suspecting I'm merely acting anorexic. I most assuredly am not. They want to put me on a tube. I would really like to get off the gluten in order to ease my system and gain weight, as I'm clearly reacting to it and have been deluding myself for the past year trying to recover from this surgery, but I'd also *REALLY* like some diagnostic confirmation so my doctors & family all stop looking at me like I'm crazy, and that so I can act with appropriate caution/freedom in my dietary future. 4) Do my childhood experiences line up with any celiac sufferers? I've heard about enamel defects, but missing teeth or crazy constipation? Obviously osteoperosis could connect, and doesn't *really* line up with my anorexia considering I was already fully grown. 5) Is there any way to get EMA/HLA blood tests done in Canada (BC)??? It's really frustrating that my only chance for any confirmation is waiting months and months here for another biopsy, especially considering how dire the need to improve my digestion is ASAP. I imagine if I could get an EMA test & it came back positive I would just take that as my confirmation and be able to move on with confidence here. 6) Is it common for celiac sufferers to find themselves reacting to FODMAPS and/or histamines in foods while they're  still maintaining a gluten-filled diet? Gluten definitely isn't my *only* trigger right now, and that's probably a primary reason I haven't been led to eliminate it at. Sorry for all the talk & questions, but I'm in an incredibly challenging place right now, my head is just swimming and swimming, and any thoughts would be greatly appreciated!   Bloodwork Current, after six months of a heavy-gluten diet = Tissue Transglutaminase Ab IgA ---18.0 ---- <12.0 U/mL = normal
      POSITIVE -Probable celiac disease but this should be confirmed with a small bowel biopsy. [Tested by a multiplex flow immunoassay
      (BioPlex) method.] 

      6 months ago = Tissue Transglutaminase Ab IgA ---13.0 ---- <12.0 U/mL = normal
      BORDERLINE - Borderline anti-tTG. Suggest repeat if clinically indicated.Consider the possibility of celiac disease - a small bowel biopsy may be required. [Tested by a multiplex flow immunoassay
      (BioPlex) method.]

      2012, prior to negative biopsy = Tissue Transglutaminase Ab IgA ---24.0 ---- <20.0 RU/mL = normal
      Weak positive anti-TTG. Consider the possibility of celiac disease - a small bowel biopsy may be required.
