Are RNA tests accurate for testing for HIV?

Yes, but...: The HIV RNA tests are checking for the presence of certain parts of HIV. When positive, it can give us an idea of how much HIV is present.

How accurate are IGG blood test for herpes for person never having an outbreak? Partner tested positive for hsv2.

How accurate are IGG blood test for herpes for person never having an outbreak?  Partner tested positive for hsv2.
