Cmv Infection (Definition)

CMV infection can have a wide range of symptoms from no symptoms to symptoms of fever and fatigue (resembling infectious mononucleosis) to severe symptoms involving brain, ...Read more

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your lab data indicates that you had EBV infection, like most adults have had. If you have no symptoms, there is nothing to be concerned about. ...Read more

How long could the IgG in Lyme disease stay positive?Could it stay positive more than 5-10 years? I know the IgM ab convert to IgG just want an answer

How long could the IgG in Lyme disease stay positive?Could it stay positive more than 5-10 years? I know the IgM ab convert to IgG just want an answer

Yes,positive 20+ yrs: Research suggests igg antibodies can persist at least 20 years after infection. While igm antibodies appear first, unlike other infections they often persist ; are a good indicator of persistent infection. One may have chronic lyme with or without persistence of igg antibodies. Chronic lyme is difficult to fully eradicate ; no current test proves that it is no longer present in your body! ...Read more

Lyme IgG/IgM Ab result is <0.91."Reference interval:ISR 0.00-0.90,reference interval for neg is<0.91." Is test tesult neg with above 2 refer, interval

Lyme IgG/IgM Ab result is <0.91."Reference interval:ISR 0.00-0.90,reference interval for neg is<0.91." Is test tesult neg with above 2 refer, interval

Neg;might have Lyme: This is a negative result but does not mean you don't have Lyme. The type of test you had will be negative in at least half of those who have Lyme. I advise you get a Western Blot from IgeneX but even that may be negative in 20% of those with Lyme. See http://www.betterhealthguy.com/lyme/testing for more info. ...Read more

What does this mean? My EBV AB VCA IGG is 239. my IGM is 36

Mono test: The EBV antibody viral capsid antigen IgG appears within 7 days after infection and last for life. The IGM antibody appears in 7 days, but lasts 3 months. Labs are various on tere actual levels, so you will need to talk to your provider about the levels in accordance with the labs norms. ...Read more

Whats the meaning of Herpes Type 1 IgG- Serum Positive, Herpes Type 2 IgG - Serum Negative and Herpes 1+2 IgM Ab Serum Negative? Thats my results

Whats the meaning of Herpes Type 1 IgG- Serum Positive, Herpes Type 2 IgG - Serum   Negative and Herpes  1+2 IgM Ab Serum Negative? Thats my results

HSV1, no HSV2: The results mean you are carrying herpes simplex virus type 1 (HSV1), usually from oral infection in childhood, so you probably have had it for years. But if you have had symptoms that suggest genital herpes, it could be a genital infection. You do not have HSV2, the usual cause of genital herpes. I takes up to 12 weeks for positive results, so these results do not exclude recent infection. ...Read more

Lyme,Total AbTest/Reflex.Lyme IgG/IgM Ab < 0.91;Reference Interval:ISR 0.00-0.90; negative <0.91;equivocal 0.91-1.09;positive >1.09.Is above + or equi

Negative: If a patient's lab test result is <0.91, and the lab says the reference range for NEGATIVE is <0.91, then the test result is NEGATIVE. Of course, numbers are just numbers, so the doctor needs to see the numbers in the context of the whole patient in order to make sensible and accurate conclusions from the numbers. ...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.

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

My Lyme igg/igm ab test came back at .98. The test range is 0-.90. My doctor says this is negative, although it says high on the test. Is she right?

My Lyme igg/igm ab test came back at .98.  The test range is 0-.90.  My doctor says this is negative, although it says high on the test.  Is she right?

Merits further tests: With an uncertain test result, a western blot test is appropriate, one that tests for antibodies to several lyme spiroochete body parts, both for igm and igg. Igenex labs in palo alto ca has a very precise western blot test and you can get a blood draw kit with instructions for free (at least your doc can order it) also suggest a cd57 natural killer cell test available through labcorp (only). ...Read more

Lyme disease ab plus reflex to igg, igm-wb blood test done today. How long for results and how accurate are they?

Lyme disease ab plus reflex to igg, igm-wb blood test done today. How long for results and how accurate are they?

About a week: The regular lyme test is specific but not very sensitive .There can be many reasons for a false positive result. If it is positive on the screening test it is then sent for the more sensitive western blot test. If the igm test is positive it could represent a recent exposure to lyme disease if the igg is positive it indicates a more distant orast exposure. If the igm is positive you should be eval. ...Read more

Old or recent herpes infection? Herpes 6 ab panel blood results: herpes virus 6 igm neg:<1:10<1:10(my value) herpes virus 6 IgG pos<.99 mine 13.56

I don't get it: Herpes 6 is the roseola virus which infects nearly all of us since early childhood. There is speculation about some possible indirect relationship to multiple sclerosis. It is not an std! it is not the same as herpes simplex which is responsible for genital herpes or cold sores (hsv 2, hsv1). Why test for hsv6?. Acyclovir will yield no benefit for this unless you have a (rare) acute hh6 infe. ...Read more

Confused by results bc had mono 15 yr ago.. Epstein barr VCA ab (igm) < or = 0.90 epstein virus VCA ab (igg) 3.51 epstein virus (ebna) ab (igg) >5.

Makes perfect sense: Igm antibodies rise only during the actual, acute infection. They then fade away and are replaced by the various igg antibodies, which are the ones that provide lifetime protection against the same strain of the virus. So your numbers are consistent with the fact you had mono years ago. There is no igm, and positive igg levels. So you are immune and do not currently have mono. ...Read more

I had blood test for Chlamydia. Result says IgG Ab >/= 1:16 and IgM Ab < 1:16. Does it mean that I had it in the past but not currently?

I had blood test for Chlamydia.
Result says IgG Ab >/= 1:16 and IgM Ab < 1:16.
Does it mean that I had it in the past but not currently?

Maybe past infection: The chlamydia blood tests are pretty much useless. This only indicates you have had infection sometime in your life with chlamydia, or with related non-STD bacteria. (For example, Chlamydophila pneumoniae causes bronchitis etc, is very common, and also give pos result on the blood test.) It's a useless test to diagnose current infection. If at risk, you need a vaginal swab or urine test. ...Read more
