Test Results...

I was reading a few posts on here about doctors misreading test results. I consider myself more versed than the average layperson in medical laboratory tests, being that that's my career goal. My test results seem negative to me but I want to check.

I've noticed that the numbers people have been giving, even negative test results, are very different than mine and I suspect it might be different units of measurement?

Anybody have test results that look like this?

Component Your Value Standard Range Units

GLIADIN IGA, DEAMIDATED 4 0 - 19 units

Negative 0 - 19

Weak Positive 20 - 30

Moderate to Strong Positive >30

GLIADIN IGG, DEAMIDATED 3 0 - 19 units

Negative 0 - 19

Weak Positive 20 - 30

Moderate to Strong Positive >30

TRANSGLUT IGA <2 0 - 3 U/mL

Negative 0 - 3

Weak Positive 4 - 10

Positive >10

Tissue Transglutaminase (tTG) has been identified

as the endomysial antigen. Studies have demonstr-

ated that endomysial IgA antibodies have over 99%

specificity for gluten sensitive enteropathy.

TRANSGLUT IGG <2 0 - 5 U/mL

Negative 0 - 5

Weak Positive 6 - 9

Positive >9

TOTAL IGA (LCA) 171 70 - 400 mg/dL

Thanks in advance.

They all look normal to me.

But keep in mind you still might have a gluten problem without being Celiac. I'm not sure if you've had the gene test, but if not you should ask to have that done. My GP said it gives a good indication of whether someone will develop celiac disease or have a sensitivity to it.

Good luck

This report confuses me as I don't see exactly what your results are.

Is this right:

GLIADIN IGA, DEAMIDATED 4 0

GLIADIN IGG, DEAMIDATED 3 0

TRANSGLUT IGA <2 0

TOTAL IGA (LCA) 171 70 - 400 mg/dL

These tests only give information about autoimmune gluten sensitivity. The other types of gluten sensitivity are wheat and related grain allergy and non-celiac sprue. I found the genetic marker test to be helpful.

I agree. It looks negative to me too.

As you're probably learning, medical laboratory tests can have different reference ranges on ELISA and other tests that are in arbitrary units. Even when labs are in measured in SI units like pg/mL you can still get different reference ranges from one lab to another.

Mari, the result is right next to the test name, immediately followed by the reference range.

Thanks guys- I was pretty sure it was negative since it gave reference ranges, but I wanted to make sure. A positive test sure would have given me more motivation to go gluten free, but I'm on week two and have only had one bad incident- a so-called gluten free pizza that made both me and my gluten-sensitive boss pretty ill. I had just had an amazing gluten-free pizza from a pizza place in a different city so I guess I was feeling lucky. Ay yi yi.

      Iron loss and potential celiac.

      Welcome to the celiac.com community, @ThomasA55! Before I give my opinion on your question about whether or not you should undergo a gluten challenge, I would like to know how you react when you get a good dose of gluten? Are you largely asymptomatic or do you experience significant illness such as nausea and diarrhea? You mentioned intermittent joint...

      We Keep Getting Glutened With Vegetable Oil

      This is way past due for your post. I have Celiac and have been recovering for more than a year. Doing well. Used Essential oil to day to fry some chicken. Read the label all good. Then ate some chicken. Here comes the gluten reaction. I haven't had a gluten reaction since year. I am angry. I have been so careful with this crap and don't wan't any...

      Iron loss and potential celiac.

      Hey everyone. I'm a young adult who had very high iron in 2024. 64% saturation 160 ferritin. In 2025 I had far lower iron. 26% saturation and 130 ferritin. I know this is still in range but it seems to be a large drop. That combined with the fact that I developed some intermittent joint pain between the two years makes me wonder if I could be celiac. My dietary...

      Edy's and Dreyer's ice cream

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I...

      Edy's and Dreyer's ice cream

      Do keep in mind that many of the newly diagnosed have lactose intolerance. This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse. When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved...

Are you largely asymptomatic or do you experience significant illness such as nausea and diarrhea? You mentioned intermittent joint pain before you began experimenting with a low gluten diet. Anything else?

      Hey everyone. I'm a young adult who had very high iron in 2024. 64% saturation 160 ferritin. In 2025 I had far lower iron. 26% saturation and 130 ferritin. I know this is still in range but it seems to be a large drop. That combined with the fact that I developed some intermittent joint pain between the two years makes me wonder if I could be celiac. My dietary intake of iron was pretty steady (mostly in the form of red meat). I did carnivore (therby eliminating gluten) for a bit after the second test and felt improvements in my joints and digestion. I still consume gluten occasionally socially, for religious reasons, and through cross contamination/food sharing. For these reasons, I would need to know if I had it, because although my lifestyle is low gluten its not at the strict level it should be if it turned out I was celiac. I will get a gene test first and hope I don't have DQ2.5,DQ2.2, or DQ8, but if I had any combination of those do you guys think I need proper screening through a gluten challenge / blood test? Other context. From 2024-2025, my b12 stayed about the same in the mid 600s folate went up slightly, but I heard it takes longer for celiac to affect the absorption of these. ANA negative, CRP low, ESR low.  I don't know how much noise exists around the saturation and ferritin, but it caught my eye and Celiac seemed like a possibility. I'm under no illusion that it is probable that I have celiac, only that it may be worth screening given my overall profile.

Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/
