What Do Test Results Mean?

Rate this topic

Recommended Posts

I recently got a Celiac Disease Complete Panel. I cannot get a response from my doctor as to these results. One result came back as high. Could someone please tell me what it means? I will post all the results in case that is needed.

Celiac Disease Complete Panel:

Immunoglobulin A, Qn, Serum 218 mg/dL reference interval 70-400

Deamidated Gliadin Abs, IgA 76 High units (>30 is moderate to strong positive)

Deamidated Gliadin Abs, IgG 3 units 0-19 reference interval

t-Transglutaminase (tTG) IgA <2 U/mL 0-3 reference interval

Tissue Transglutaminase (tTG)has been identified as the endomusial antigen. Studies have demonstrated that endomysial IgA antibodies have over 99% specificity for gluten sensitive enteropathy.

t-Transglutaminase (tTG) IgG <2 U/mL 0-5 reference interval

I am wondering what the High Deamidated Gliadin Abs, IgA means? Thank-you for any help.

I just got mine back and had the same high lab as you- mine was >100. /: I am assuming from what I've been reading that it is some sort of immune response to gluten...just not sure of the nature (celiac disease or not). I requested some more tests and my NP obliged so I had the IgG labs drawn today...my total IgA was only 106- "normal" by the labs but compared to average adults it is low so I thought I'd better get the IgG labs too...thanks in part to the other members who suggested that (:

I guess I am of no real help b/c I am still trying to figure out exactly what it means too...(; Nice to know you aren't along though, huh? Do you have a follow up appt soon?

All put together, these are the celiac panel tests:

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

The first two are the older generic-type tests not relied upon much any more. The Anti Tissue Transglutaminase (tTG) is the all-time favorite of doctors; although this test can be positive in conditions other than celiac disease. If this test is positive and you subsequently run the Anti-Endomysial (EMA) and that is positive, then the two tests together confirm celiac (the EMA is not run automatically (because it's expensive) if the tTG is negative). The Deamidated Gliadin Peptide (DGP) is the newest of the celiac tests and has a 99% specificity for celiac disease. If this test is high, it pretty much means you have celiac disease. Nevertheless, most doctors (especially the GI's) still like to do the endoscopy with biopsy to confirm the diagnosis. The last test, total serum IgA, is a control test to make sure you produce normal amounts of IgA antibodies. If you fall within the normal range it validates the results of the other tests. If the IgA versions of the tests are invalidated by a low total IgA, and your results are negative, then they run the IgG tests. You both had normal total lgA. In mary's case they went ahead and ran both IgA and IgG versions of the tests.

I believe you can both anticipate notification from your doctors that you are celiac positive, and will probably be referred to a gastroenterologist (if that was not the person who did the testing) for an upper endoscopy with biopsy.

I really appreciate the responses. Honestly, Mushroom, your wonderful explanation was a little over my head. I apologize if I sound ignorant. But atleast I got a possible answer. I meet with my doctor again on Wednesday to see what he says. Thank-you for the information. I'm sure I will continue trying to dissect it throughout the weekend! I may post again on this site if I have further questions. Again, thank-you. This is a bit scary for me but I would be very happy if I felt better.

It means you need a biopsy. DGP-IgA, your positive test, indicates celiac most of the time but not always. There is a little question in your case because all the other tests are negative. Sometimes people with only DGP-IgA have no damage when the biopsy is done. That's probably why your doctor hasn't commented and referred you to a GI.

Your immune system is recognizing gluten and even if your doctor decides you don't have celiac right now, you would be at serious risk for getting it. Once you have your biopsy you should try gluten-free. I bet it will help you feel better. :)

    • Also I should add that in the 12 weeks, my vitamin d plummeted and now am deficient. Would you guys accept a celiac diagnosis (I am pretty confident that I have it- I was sad before the challenge that I couldn’t eat gluten anymore. Now after the challenge i am EXCITED to never eat it again as I feel like such crap now) or can a positive diamodated Gliadin  IgG indicate anything else? Or is it specific to celiac? I am happy to get a diagnosis,  but want to make sure it’s the right one. I wish I trusted my doc more (example- 3 days ago they called and said congrats, no celiac, u can eat gluten!! The doc signed off on it. But I looked at my results and pointed out that the deamidated IgG levels were not reported yet. The doc said whoops my bad. The next day they came back positive and I got another call & they said, nevermind, no gluten, you’re positive! They are idiots). 
    • Looking for advice and also to help those undergoing testing. I went to my general practitioner back in August with nausea, bloating, diarrhea, migraines, sluggishness, and a feeling of general unwellness. I was eating a gluten diet at the time. My doc ordered the dual antigen screen- it came back positive for celiac. He set up an appointment for me with a specialist. I called the specialist and they could get me in 8 weeks later. I asked the specialist if I went gluten free is this would affect any testing. They said “no” that I was in a gluten diet for so long I would be fine. However, 8 weeks later, the blood test showed no celiac- my results were normal after 8 weeks on a gluten free diet. I felt great, for me the turnaround was almost immediate- in a week or 2 I felt amazing. But that didn’t help with getting accurate results (mostly wanted to rule out another autoimmune disorder). I then went on gluten for 7 weeks (I ate a lot of gluten- like at least a bagel a day and much more on some days- I wasn’t messing around, I wanted an accurate diagnosis)and repeated the blood test at 7 weeks. It came back a very weak positive for deamidated gliadin abs iGg. I then underwent a endoscopy because the doc said that number, although positive, was not high enough to go off of. The endoscopy came back normal- however, the doc noted that higher levels of antibodies were found but not in the “abnormal range.” So, they were present, just not in crazy levels. I then kept eating gluten- I should note my doctors SUCK (could do a whole other post just on this- I have been my own doctor pretty much). I just took another blood test at 3 months eating gluten. My levels are now SUPER high for deamidated Gliadin abs IgG. The doc is confident I have celiac. Question is- my doc is so bad, I wanted to check here to make sure that it indicates celiac. I also wanted to help others as I know there’s lots of conflicting information on how long to do a gluten Challenge. For me, it took 3 months. My gut tells me I am early stage celiac- I don’t have full blown damage yet, but if I keep eating it I am sure it will do some damage. Just wanted to highlight this as if your case isn’t super bad yet, you may have to eat gluten longer- everyone is different. Any advice on my results would be awesome!
    • Hi Matt,  Thanks for taking the time to reply!  I completely agree haha.  Thanks for the links - I'll give them a read over!  I think it was a mixture of the first time travelling with being gluten-free and the added bonus of the language barrier, it made me dread meal times when usually food is the first thing I think about when travelling to new places! Again, I think the planning element was also a factor, not being able to walk past a nice bakery without walking in - why do most Berlin train stations have bakeries in everyone?!?! THE SMELL!!!  Haha, good excuse! Could have used that in the hotel restaurant (arrived late the first night) and the only avail dish was a dry chicken Caesar salad (literally 3 thin slices of chicken, 5 cherry tomatoes and a plate of lettuce).  I am I'll give the website a look over too - thank you! My app's with my consultant are every 6 months, basically was just sent away with no info/advice given and feeling the struggle now that reality has set in that this is for good!  Hope you are well! 
    • Gluten is a protein smaller then blood,bleach does not kill it as it is not a germ. I would replace scratched pans. baking dishes, tubaware, wooden utensils, colanders, etc. Throw out crumby condiment jars and any non gluten-free spices and condiments. Cast Iron can be saved and some metal utensils by putting in your oven self clean cycle, 500F will destroy the protein. I always tell people easy ways to get started on new cookware, nordicware microwave cook ware, omelette makers, steamers, rice cookers, grilling plates (do not forgot the splatter cover), This way you can have a cheap and easy meals, a new crockpot and use crockpot liners is great for soups, I suggested a combo rice cooker/crockpot/steamer as a great investment. OH if you want a nice clean safe prep area/counter/eating place mat, look up freezer paper/butcher paper. I did a post on where to get it in bulk awhile back. But laying it out is perfects, and makes clean up a breeze. Foil sheets in baking dishes works great for a extra precaution but if you have any with baked on stuff or scratched look at getting new ones. PS took me over  months to start feeling much better. Sometimes the improvement is minor and you have to think back to the worst you had. It does improve but normally big changes are after a year.

    • It sounds like your hives resolved.  I had a six month bout with them.  Antihistamines really helped.  My doctors are not sure if Mast Cell or autoimmune is the root cause.
