Has anyone had any experience with the amount of time required to wait
for a blood test after exposure? If have read various ranges from 2
weeks to 6 months. It seems like 6 weeks should be enough for the
newer tests, but has anyone out there tested neg at 6 weeks and later
tested positive? I know the recommendation is 12-16 weeks to be
absolutely sure, but what percentage of people are still not testing
postive after 6 weeks? Is it just the difference between 95% and 99%
when going from 6 to 12 weeks?

Blood tests are expensive, so to make sure you get enough out of your $$,
wait the recommended 12 - 16 weeks. If you test earlier than that, you'll
just have to retest later.

I'm trying to find a chart of graph of antibody development over time
after exposure but haven't found such a thing, yet.
Deep down in the PDF file at the link below, however, is this:
"Another common situation is the asymptomatic person who may have
recently been exposed to genital herpes. If this individual is within
8 weeks of exposure, genital herpes is difficult to diagnose, as many
assays are most sensitive when the antibody profile has fully
developed (usually after 68 weeks [Figure 5])."

[Figure 5 is not legible, by the way]
I would guess that reliability of a test at six weeks is around 50/50
or worse.
Still looking...

John,
There is a 12-16 range because everybody is different when it comes to the
herpes virus.
Not everybody will test correctly at 6 weeks and that is why they use that
12 - 16 range.
If folks want to be certain . . . they can always wait for the 16 week
range. If somebody has a flare up they can have cultured then they don't
have to wait. The important thing is to get that culture done within the
first 24 ours of the outbreak.
