However, if this is herpes and new infection, a blood test now will only tell you your status prior to this. It can take up
to 3 months for it
to be accurate due
to antibodies forming (which
is what it detects).
If you had a culture - that's good. It may take a week or so to come back - be sure they type it if positive (as in HSV1 or HSV2). That's also very important.
At this point you're going to have to wait for that, and then go from there with blood testing.
