Immunoglobulin M (Definition)

There are 5 classes of immune proteins: igg, iga, igm, ige and igd. Igm fights infection. If you produce too little then infections may occur and you have hypogammaglobulinemia. If you have too much you ...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

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

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

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

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

Can't tell HSV1 vs 2: Your doctor is mistaken. You have HSV, but th HSV 1/2 test does not distinguish between HSV1 (usuallly oral) and HSV2 (almost always genital and always an STD). In India, most people have HSV1 by age 20, usually acquired in childhood, so that's the likely explanation. But you could also have HSV2. You need a truly type specific blood test to tell whether you have only HSV1 or both types. ...Read more

I have no symptoms of any type. I tested my std panel with hiv test so all came negative hsv1/2 IgM neg. And hsv1/2 IgG positive. Am I hsv neg or not?

You don't have it: If you never had any HSV symptoms then you don't have HSV. It's a clinical diagnosis so the blood test isn't useful. With IgM negative you likely don't have HSV. ...Read more

Acute infection: A rise in IgM antibody against a particular antigen gen indicates either an acute infection or reinfection. One can consider more reliable testing for HSV than antibody testing, e.g. PCR or culture, in light of a chronic history for a better long term follow up and disease management. ...Read more

My Hsv 1 & 2 IgG is 5.88 index value and HSV 1&2 IgM is 0.11. Please tell me what does it mean?

Herpes: Your test results indicate that you were exposed to Herpes virus at some point in your life, not sure when. The low IgM might suggest that it's not recent exposure, but IgM in this virus is not very accurate or useful. Your test did not specify whether your exposure came from type 1 or type 2 or both. If you have an outbreak ask your doctor for treatment medication. ...Read more

Unprotective sex 4 weeks ago - IgM negative, HSV IgG positive (17.40) - is IgG very high for a recent exposure? or i already had it before 4 weeks?

Unprotective sex 4 weeks ago - IgM negative, HSV IgG positive (17.40) - is IgG very high for a recent exposure? or i already had it before 4 weeks?

Herpes: Most likely, you had herpes before this encounter and you didn't know it. That's somewhat common-people are infected but don't know their status. These labs show that you've been infected at some time in the past-although there is a difference between HSV1 and HSV2. The first is the 'cold sore' virus that occurs on the lips, the second is 'herpes' that occurs on the genitals. Use condoms 2 be safe ...Read more
