IgG positive/IgM negative - what does it mean?

Recommended Posts

alexal

My girlfriend had an STD test. The results say:

"IgG antibody to HSV2 = positive (+2) @ 1:10 dilution and positive (+1) @ 1:100 dilution.

She then had a hsv2 IgM test and it was negative.

She has been sexually inactive for 7 months BEFORE she got the tests.

We have received mixed opinions from doctors on what this means, and have researched it on the web but can't figure it out.

Please help. What does it mean?

I'm not familiar with this type of result format.

Usually, the test indicates a number for HSV-2 and the threshold for a positive result. For example, 3.25H, and the cutoff value of 1.10.

If they also tested for HSV-1, then a similar format for that result.

Do you know which manufacturer's IgG test you took? There are several HSV IgG tests on the market.

Maybe

she needs to consider getting another test...? The western blot test is considered a good one. Sometimes a blood test will show up negative because the person has not waited at least 3 months from exposure to test. It sounds like she needs to take another test.

I cannot comment on the IgG result, but disregard IgM result it is not a reliable indicator of infection.
