what is difference between IgM and IgG for western blot for lyme. positive for IgM but not IgG, what does that mean? tks

Recent infection: Hi. IgM is present only with recent infection. After IgM levels fall away, IgG takes over for ongoing and recurrent exposure to antigen. (The antibodies in this picture are IgG's). I'm glad your doc was on the ball. She/he may have saved you a world of hurt by making the diagnosis promptly. Good luck! ...Read more

Reactivated EBV 9 months after first infection. Could i be immunodeficient? Antibody count: 65 ab VCA igm; 53 ea ab igg; 431 ab VCA igg; 289 ebna igg.

Reactivated EBV 9 months after first infection. Could i be immunodeficient? Antibody count: 65 ab VCA igm; 53 ea ab igg; 431 ab VCA igg; 289 ebna igg.

No: Unfortunately ebv stays alive forever in one's lymphocytes and can get activated easily in susceptible people without known immunodeficiency. However you may call that an immunodeficiency given that all people have been infected with it yet only few would have recurrent ebv problem. ...Read more

Herpes antibody test 2.05 IgM for HSV-2 and 0.05 IgG for HSV-2, do I have the viris or not? My Dr. said that he thinks not, I don't know what to think

Herpes antibody test 2.05 IgM for HSV-2 and 0.05 IgG for HSV-2, do I have the viris or not? My Dr. said that he thinks not, I don't know what to think

What does a high EBV viral nuclear capsid antibody, a high EBV viral capsid antibody IgG and a high IgM EBV viral capsid antibody mean, what's it mean?

Likely immunity,,: You've got antibodies to the ebv which likely means you were infected at some time in your life and you recovered and now your body has circulating antibodies to it. An igg antibody in particular indicates long term resistance. This virus usually causes asymptomatic infection so you probably fought it off and weren't aware of it. Best of luck. ...Read more

High IgG antibodies but negative igm. What does this mean?

High IgG antibodies but negative igm. What does this mean?

Remote infection: Igm is the first class of antibody made to a microbe and after several months the immune system starts to make igg class of antibodies and then the immune system stops making igm. If all that is found is igg to a particular microbe it means that you were infected over about 6 months to many years previously. ...Read more
