Can it take a year for HSV results to become positive? Yes, but it is very rare. Considering the rock-solid evidence you didn't have herpes, as we discussed in the other thread, this result is 100% conclusive proof of the same conclusion. You definitely don't need any further testing. Accept the good news that you are not infected with HSV of either type and move on.
Let's not have any ongoing discussion either here or in the other thread.
