Question About Blood Tests And Results

Hello everyone!

 

I've received my blood test results after being on the gluten challenge, it seems they are negative. I do have a question though regarding the tests done - there is no AGA - IGA as I have seen on some other tests.. is this important?

 

Results:

 

IGG   9.10 g/L    (7.0-16.0)

IGA   1.69 g/L    (0.7-4.0)

IGM  1.39 g/L    (0.4-3.0)

 

AGA igG   <7

T-glutaminase   <1

 

(Negative is <20)

 

Thanks :)

Getting as many celiac tests done as possible is always a good idea because the tests can miss a minority of celiacs, up to 25%.  You are missing quite a few of the tests.  If you still suspect celiac disease could be a problem for you, you may want to request more tests.  This is all of them:

 

  • tTG IgA and tTG IgG  (tissue transglutaminase)
  • DGP IgA and DGP IgG (deaminated gliadin peptides)
  • EMA IgA (endomysial antibodies)
  • AGA IgA and AGA IgG (anti-gliadin antibodies) - an older, less reliable test largely replaced by the DGP tests 
  • endoscopic biopsy (6+ samples taken)

You need to still be eating gluten for the tests to be accurate.

 

The AGA IgA ia not overly important.  The DGP tests, and the other tTG test would serve you better if you test more.

Thank you very much nvsmom. I am having a biopsy in a fortnight. I will definitely request those tests!

 

ETA: Does anyone know if all of these tests are available in Australia?

 

It also says on my results that the AGA IgG result is the "deaminated gliadin peptide igG antibody".... is that the AGA test or DGP?

The deaminated gliadin peptide igG is the DGP IgG test, but  AGA IgG stands for anti-gliadian antibody IgG .... at least in North America. If they said it was the deaminated gliadin peptide test then I would assume it was what we call the DGP test.  I have no idea why they called it the AGA though....

 

Perhaps try asking if it is the newer test (came out about 5 years ago I think) or the older gliadin test, that could clarify it for you.

I will definitely do that, thanks.

 

I had a look at some websites of Australian pathology labs and they definitely have DGP tests and AGA tests as North America does... hmm...

      Testing for celiac

      By Bebee · Posted

      I am new here, I have been diagnosed with Microscopic Colitis (Lymphatic) years ago and have been gluten-free, DF since, but I still can have occasional bouts of diarrhea (still trying to figure that out).  I also have MS, Hypothyroid, Arthritis, Reynaud's and my rosacea has been acting up lately.  What treatment is suggested to help with rosacea?  I would like to know too if there is a test for celiac if you have been gluten-free?   Thank you, Barb

      Newly gluten free… withdrawal?

      By K6315 · Posted

      Well, that's interesting. I am lactose intolerant and have been managing that for years. I'd be interested in seeing if that changes once I feel better from not eating gluten (one thing at a time for now, though). Helpful to hear about the avenin. I will do some digging and pose that to the dietitian. Grateful for your feedback.

      Nandos improper preparion celiac childrens food

      By kate g · Posted

      Recently my daughter ate in nandos harlow I rang in advance to speak about the celiac protocals and learned that childs portion chicken nandinos is cooked on the same grill as garlic bread even if they are celiac! Even if you clean it this is not good practise and will be making many children ill. I learnt adults butterfly chicken cooked on a grill purely for chicken.  This is fine and what we ordered however nandos need to take note of your practises for the safety of celiac children. my daughter has been ill from their nandinos chicken before and i emailed head office and they wouldnt accept responsibility

      High blood test numbers - with scales. Any advice?

      By Scott Adams · Posted

      I agree with @RMJ, you have multiple positive tests so celiac disease is likely.  This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease.
