Could You Help Me Interpret My Results?

I had already been off gluten for a month and a half when this test was taken. What does this mean?

IGA= 40 H

IGG= 4

Nobody has explained what that actually means?

Is it possible for these tests to be done without a celiac panel, thereby making them void because they are measuring a different IGG IGA antibody? Or is there only one type?

Those results in and of themselves are meaningless, because they do not state which kind of IgA and IgG antibody they are measuring. There are three possibilities that come to mind: could be AGA, tTG, or DGP. So the results would need to state AGA IgA, etc., and they would need the reference ranges that the lab uses when doing their assays to elucidate the numbers.

It says AB (IGA, IGA)

If you had been off gluten for six weeks and AGA IgA came back that far over positive, it definitely warrants further investigation. How long altogether have you been off gluten now? Depending, it probably would not be worth running the full celiac panel at this point

Anti-Gliadin (AGA) IgA

Anti-Gliadin (AGA) IgG

Anti-Endomysial (EMA) IgA

Anti-Tissue Transglutaminase (tTG) IgA

Deamidated Gliadin Peptide (DGP) IgA and IgG

Total Serum IgA

which is what should have been done. But it might be worth doing the endoscopy with biopsy. Can you self refer to a GI or do you have an HMO?

Can you contact the place or the doctor's office which issued the results, and get the rest of the missing numbers that should go along with what you have ? Each lab uses a different range to compare scores. For example, it should say something like "your score = 40, where 1 to 10 is negative, 11 to 20 is mild (maybe, or equivocal) , and over 40 (greater than, >, ) is positive."

I just totally made up those ranges for the purpose of illustration, by the way. What you have so far, is like saying you're driving 40mph in the gluten gliadin antibody zone.... what was the speed limit in Celiacville ?

I have been off gluten now for 4 months, and I am too afraid now to go back on it. The ranges for the IGA were less than 20 units. The ranges for the IGG was also less than 20 units.

He did not do the whole panel, he was a very weird alternative doctor that went farther than alternative to the point of scamming me for money. However, I do have copy from Quest of the blood test.

I can self refer, which I am considering since my regular doctor does not give me any direction. However, since my husband and I had been trying to get pregnant I am not sure if I could do a biopsy? Considering, I am not yet sure if I am pregnant. However, I suppose it might be useful to do other tests that do not require me to be put under.

An endoscopy does not require general anesthesia. They give you a sedative, and a medication called Versed so that you do not remember the procedure. You wake right up after it - there is minimal recovery time. I think it is something you could do even if you were pregant but you would want to check.

Sorry to ask about this in your thread iangone, but I've been very confused about all this myself.

I never got my blood tests back myself (of course I didn't, I'm canadian, they keep you in the dark as much as they possibly can), however what they tested was positive. When I prodded the GI who did the biopsy about my IgA and if IgA specifically meant gluten antibodies, he said no it didn't and that he had no way of knowing for certain if my antibodies were towards gluten or something else. But that seems in contradiction to what you've posted, here and elsewhere.

I don't even have the results of my blood test, but I have the GI and my conversation with him regarding IgA and in my medical records I have someone saying my IgG is high which I thought I didn't even have tested as no one else has referred or talked about my IgG being high.

I know I have celiac disease because the biopsy came back positive too, but in terms of understanding literature and what tests are relevevant and how they work and what they mean, I'm very, very confused.

cavernio, surely if you ask the doctor's office they will give you a copy of your blood test results? What possible reason could they have for denying them? I don't know if under Canadian law they are required to do so, but it is a pretty harmless request, especially since they are positive.

I got a copy of all the files my doctor had on him, but the blood tests weren't in them. It was probably because when I got tested he wasn't my doctor and it was just one I saw in a walk-in clinic. And it was a pain in the ass to get the copies too. They aren't allowed to just give you your files though, they have to give you copies.

You wouldn't believe the lack of healthcare I receive. I've been trying to get my vitamin levels checked since before I even asked for the celiac diagnosis. I still can't manage to do it, not beyond b12 and iron. And I STILL haven't managed to get my t4 and t3 checked along with tsh. One of my blood tests the LAB wrote down that it was unnecessary to test for t4 since there was no family history of thyroid issues.,Which is actually wrong, but it's beyond ridiculous that they have any sort of power over what I get tested for and that they can ignore what the doctor ordered. The other one I thought I just got a few months ago was ordered by my previous doctor and he said my thyroid was fine. But when I got my hands on my files since he's no longer my doctor, the results don't show any thyroid tests at all!

Back on track, regardless of my personal results, am I right in saying that it is very possible to test for gluten/gliadin specific antibodies in the blood, and that my GI was wrong? (Well he could be right in that the labs HERE don't use that test, but that's not what he said, he said that it was impossible.)

One of the tests is called AntiGliadin Antibodies (AGA IgA and IgG), but it is an older test and is not considered to be as sensitive as the newer DGP (deamidated gliadin peptide) test. But all the celiac tests are checking for those little antibodies - they just do it i different ways. Some ways work for some, others work for others. Why it is considered necessary to run the entire panel by most of us, but not by the docs, unfortunately.

Go back to that walk-in clinic you went to and get your copies from them :) As you have learned, if you don't have the results in your hand there is no evidence that they were actually done or what the results were :ph34r:

Last time I went to the walk-in clinic to get the results they acted like I was an idiot for going there for the results.

I have biopsy results. One of the 2 GI's I saw should have them.

thanks, didn't know what all the abbrev. stood for.

    • Just recently I've had a lot of soreness in my mouth. I have small apthous ulcers on the underside of my tongue (even when I'm well I find I can get them by just eating salty potato chips).  I also have had to have a lump removed from my mouth which turned out to be benign.  Most of this I put down to stress, not enough sleep and I'm badly anemic at the moment - women's stuff.  I have just started to supplement B12 and ferrous glucanate again which has helped in the past.  My consultant tells me that often celiacs with blood iron under 50 can suffer from these sores and if I have an infusion it should sort out the problem. Silly of me but I've just made things far worse, I believe, by consuming a few pure (i.e. gluten free) oat cookies in the last couple of days. I've avoided oats for a long while now but thought I'd give them a try again and my mouth is tremendously sore this evening.
    • No, I won't swallow it! Right now, the wound is not really open, and cold relieves the pain more than warmth, so I'm not sure how much good salt water will do. I guess I get to anticipate the day when it does open, if it does. O goody. The pain is incredible. And I'm very hungry because I'm not eating enough. This really sucks, I must say. Thanks for your other words. Yeah, it was the citrus, and the stress, and some sugary things probably did not help either. Ugh.
    • If your blood tests do come out as negative, and they might, you can ask for genetic testing to rule out celiac and an endoscopy to check for damage.  I was in a similar situation years ago. I was gradually getting more and more tummy problems, a friend suggested cutting back on gluten and bam, I felt better when I did. So, when I finally was able to find a doctor who was willing to believe I didn't just have IBS, I already knew that if I ate gluten I had major diarrhea problems and pain... so went basically gluten free. I told that to the doc and he didn't believe me... but my blood tests all came back negative. Then he did the genetic tests to rule out celiac... they came back positive. Then he did an endoscopy and found damage and diagnosed me... and sent me to a dietitian who knew less about going gluten free than I did. I've been extremely careful since then. 
    • Weak positive means you should have an endoscopy done (with several biopsies) to see if you definitely have celiac. You have to continue eating gluten until the testing is done. If the biopsies don't confirm celiac you can always try a strict gluten free diet for a couple of months to see if you feel better.
    • They offer gluten free buns at $2 a pop.   I get the grilled chicken sandwich w/gluten-free bun and apple slices.  I only put lettuce, tomato, and onions on it.   Tough keeping the bun from falling apart.   I don't have severe symptoms so can't say for sure if I ate all gluten-free.
