EMA Iga 1.24 g/L

It's in my medical records but has never been mentioned to me.

Welcome to the forum, @Toaster!

EMA is a celiac disease specific antibody test. It was one of the first antibody tests developed for celiac disease but it has fallen out of favor in recent years. It is an excellent test but expensive to administer as it requires the use of animal organ tissue (esophagus I think) in order to be run. Since then, a less expensive test known as the tTG-IGA has been developed that essentially accomplishes the same thing.

Your test result of 1.24 g/L is meaningless unless you can also supply the reference range values used by the lab. Different labs use different reference ranges for negative vs. positive. There is no standard.

The EMA test is discussed in this article along with other celiac disease antibody tests:

Thank you. There is no reference range mentioned unfortunately.

Have you been diagnosed with celiac disease or are you looking into it?

I'm looking into it. I have several quite low vitamin results which I believe may be from malabsorption. B12, ferritin, folate, vit d all very low. Re-occuring mouth issues, gut issues.

Were there any other tests besides the EMA run for celiac disease? If not, you should request them. At minimum, "total IGA" and "tTG-IGA" should be ordered. A more complete celiac panel would also include the DGP-IGA, DGP-IGG and TTG-IGG. And very importantly, you should not have been reducing gluten consumption in the weeks/months leading up to the testing blood draw.

No other tests. This was from about 10 years ago, I noticed it when checking through my all bloods to look for patterns. 

I will go back to my doctor...

Let us know what you find out, the reference ranges should appear on the original test results.

g/L, a weight per volume unit, would be a very unusual unit for a celiac specific (EMA) test.  

1.24 g/L would be in the normal range if this was a TOTAL IgA test.

Best to ask the doctor.

      Type 1 diabetes (4year old) and positieve ttg

      By trents · Posted

      Welcome to the forum, @marinke! "Type 1a diabetes (DM1) is associated with an increased risk of celiac disease (celiac disease) (1)." from: https://diabetesjournals.org/care/article/35/10/2083/38503/IgA-Anti-transglutaminase-Autoantibodies-at-Type-1 "The prevalence of celiac disease (celiac disease) in children with type 1 diabetes (T1D) is 5.1%, and it is often asymptomatic (1)." from: https://diabetesjournals.org/care/article/48/2/e13/157637/Diagnostic-Outcomes-of-Elevated-Transglutaminase So, this is 5x the rate found in the general population.

      Long term recovery

      By Mari · Posted

      Hi James47, You are less than 2 years into your recovery from Celiacs.  Tell us more about the problems you are having. Do you just want to get rid of belly fat or are you still having symptoms like gas and bloating.    For symptoms you may need to change your diet and take various supplements that you cannot adsorb from the foods you eat because of the damage caused by the autoimmune reaction in your small intestine.

      Type 1 diabetes (4year old) and positieve ttg

      By marinke · Posted

      My daughter (4 years old) has type 1 diabetes since she was 1. Therefore, every year a screening is done. We live in the Netherlands. Every year the screening was fine. This year here ttg is positive, 14, >7 is positive. IGA was in range. Could the diabetes cause this positive result? Or the fact that she was sick the weeks before the brood test?

      Shortness Of Breath (the "sighs")?

      @DayaInTheSun what were the shortness of breath symptoms for you ? And did they come on all of a sudden or was it a gradual increase in said symptoms?

      Shortness Of Breath (the "sighs")?

      By DayaInTheSun · Posted

      I had shortness of breath so much so I went to a lung doctor. I told him I get short of breath wirh certain foods, he said “Food doesn’t affect hour breathing.” I told him maybe it was an allergy  he cut me off then said “Food allergies don’t cause shortness of breathe.” I beg to differ as soon as I figured out what foods were causing my shortness of breath it went away. I also never saw him again as he was rude, condescending? And refuse to listen to me kept dismissing my problems as “you’re young.” I cut out Soy, dairy, sesame, eggs, and of course gluten. I stopped being short of breath, going on a two years now. No thanks to the doctor I saw. Figured it out on my own.
