Question : How positive is a Herpes test (blood test) if you get it 5-6 months after the possible incident?
I heard that it takes 3 months max for the antibodies to show up in the blood so i feel like it has to be really close to 100 percent but i’d like to know the percentage or an estimate

It should be a pretty accurate positive after 5-6 months of having sexual contact with some one that has herpes. Antibodies take about 3-6 months to build up enough to show positive in a blood test. I would think that after 6 months it would be 99.9 percent accurate.
If there was no break out at the time of the “possible incident” then your risk of getting herpes not likely but still slightly possible.
