Dr. Ford Said It Best: Dgp Vs. Aga

Recommended Posts

little bit of a rant...

 

ok so as I continue to research everything, I now have a good grasp on the difference between DGP and AGA and what they do and measure.  One of the first things I read was this page by Dr. Rodney Ford:

http://drrodneyford.com/extra/documents/279-gliadin-antibody-confusion-same-name-different-test.html

 

he lays things out in easy to understand terms that I truly do appreciate :)

 

I have to use LabCorp for my insurance, and I found this comical, but also sad at what they have listed on this page under Additional Information:

https://www.labcorp.com/wps/portal/!ut/p/c1/hY1LDoIwFADP4gFMHwUrLP1U1JbWWkBgQwgagkEQMBo5vVxAzSwnk0EJGqmzZ1lkj7KpswpFKCGpsolQWGCwPbwBbJIlzFbUAJeMPv7uAf7UYtvcLihGyTwNqKWNnWOCdDWGnTalJbAgxAbkowisVF_h7vG-9gZHHjidCU47mbMO_Bb64e0wUGe2P56rqlWn4hQMNnTv3GCcPqUO0nDgeRMuwpfL1s1kfMY_n_db9DKmavIBwaXRWg!!/dl2/d1/L0lJS2FZQSEhL3dMRUJGcUFFQWpNQy9ZSTV5bHchIS83X1VFNFMxSTkzME9HUzIwSVMzTzROMk42NjgwL3ZpZXdUZXN0/?testId=407254

 

 

"A negative IgA result in an untreated patient does not rule out gluten-sensitive enteropathies, especially when associated with IgG gliadin antibodies. This can be explained by selective IgA deficiency, a relatively frequent finding in celiac disease. False-positives are possible as other gastrointestinal disorders are known to induce circulating antigliadin antibody, mainly Crohn's disease, food protein intolerance, and postinfection malabsorption."

 

I HATE that they use terms AGA and DGP interchangeably.  If I was reading this, and was completely new to everything, I would think that means maybe I have Crohn's, protein intolerance, and/or postinfection malabsorption, but they are referencing AGA on this page for the DGP testing :blink:  No wonder people get confused.  Right now the only thing DGP shows is celiac, and until that is proved otherwise, that's what it is.  I've asked my GI, asked others on the board, and currently that's what DGP tests show.  I can't wait until more studies are done in regards to DGP!  Yes, I fixate on the DGP test :) They should have named the DGP test something COMPLETELY different than the AGA test.  Oh modern medicine is a love-hate relationship with me :P

 

done rant.  thanks for listening  :)

I can't get it to link correctly, so Plan B :)

 

if you're interested to see what I'm griping about when you get to the search box put in

 

Gliadin Antibody Profile, IgA, IgG, EIA

 

Edit: If I completely sign-out of my account and close my browser, and then open the browser again as a guest, the first time I click on it the link it brings me to a search page.  If I go from the Labcorp search page and use the back arrow to my original post, and then click the link again, it brings me to the actual testing page...strange...

Not sure what exactly you want us to see but ...could you copy it and paste it here?  I'll take your word that its what the lab says as I'm too lazy to look it up.  I think I had a Celiac panel done by Lab Corp before.

geez this is turning out to be quite a process :P it bothers me when I can't figure something out, and I don't know why it isn't linking...

 

Ok anyway onto the point:

 

This is a screening test of only Deamidated Gliadin Antibodies, but in the "additional information" for this screen it states the following:

A negative IgA result in an untreated patient does not rule out gluten-sensitive enteropathies, especially when associated with IgG gliadin antibodies. This can be explained by selective IgA deficiency, a relatively frequent finding in celiac disease. False-positives are possible as other gastrointestinal disorders are known to induce circulating antigliadin antibody, mainly Crohn's disease, food protein intolerance, and postinfection malabsorption.

 

Why are they discussing antigliadin antibodies if this is a DGP test, and in addition, all of their references in compiling this "additional information" section are from the early '90s :wacko:

 

I'm making a big fuss, and I didn't even get this particular test ordered :P I had the DGP tests done as part of their Celiac Disease Comprehsive Panel.
