Helicobacter Forums

Hello,

I have my blood results back and I was just wondering do you only need to test positive for one of the antibodies to show that you have had an infection? Why are there three of them?
I suspected that pylori might be my problem and my results are below.

Also, is this a common problem that all doctors are aware of? Should I just be able to show my test results to my doctor and possibly get treated?

IgG negative
IgA positive
IgM negative

Thanks

We have 5 types of antibodies in our body. Each has specific purposes. IgM is normally presented when the infection is early. IgG is when there is a long period of infection. IgA presents normally in mucous regions, eg. eyes, lungs, stomach, mouth, etc.

H. pylori infection almost always give positive IgG. I think as long as one of the antibodies showed up positive, you'll be considered as positive. I dig up a study about IgG vs IgA detection.
