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

IS THERE`S A PRESENT INFECTIOUS ? MY EBV ANTIBODY PANEL: VCA - IGM 43 VCA - IGG 1041 EA - IGG 295 EBNA - IGG 133

Yes, it is recent.: Presence of IGM indicates a recent infection. This type of antibody is released early as this carries five times the blocking sites compared to other antibodies. Presence of IGM thus suggests an ongoing attempt by our immune system to fight a current infection. ...Read more

Recently tested high levels for all 3 EBV antibodies >5 IGM,IGG,IGG(EBNA). what does this mean?

Recently tested high levels for all 3 EBV antibodies >5 IGM,IGG,IGG(EBNA). what does this mean?

Epidemiology of EBV: Studies show that the Epstein Barr Virus is ubiquitous in all human populations. Children acquire the disease and seroconvert in the first few years of life. Studies also show that EBV titers are high in young children and then in persons above 50 years old. IGM antibodies are usually seen in early infection IGG antibodies immunity or memory response. http://www.ncbi.nlm.nih.gov/books/NBK47424/ ...Read more

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

What is the toxoplasma IgG and IgM antibody test?

What is the toxoplasma IgG and IgM antibody test?

You've met it: When one meets the toxoplasmosis organism (mild flu-like or no illness), IgM usually appears and may stay around for as long as 18 months. Igg will also appear and usually stay for life, suggesting you overcame the creatures. However, they may still be alive and dormant, to re-emerge should you become immunocompromised. ...Read more

What is the test result  range for both negative & positive for HSV antibodies IgM & igg? Ex. <0.9 ... Etc

Differs by lab: What you are asking is for the normal "reference ranges" for these tests. Reference ranges are established by each laboratory based on their testing equipment and vary from lab to lab. There is no universal reference range for these or other lab tests. You would need to ask for the range at the lab where the tests were run. ...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

IgM versus IgG: You very well may have an early infection with herpes. You cannot know for certain without a follow up test. I would wait six weeks and then repeat the tests. If the IgG is still negative then, you do not have the infection. Sometimes the IgM testing picks up HSV1 and cannot distinguish it. ...Read more

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
