Thanks for you kind comments.
1. If it is one of the reliable (glycoprotein-based) tests, then yes, you can rely on the one you took.
2. If you don't have genital herpes--and it seems you don't--then it must be something else. Your gynecologist should perform the requisite examinations, cultures, or other tests to find out.
3. If what you have isn't herpes, it follows that Famvir wouldn't work. You need a proper diagnosis to know what, if anything, to do. (By that I mean that these vaginal sores may be unimportant and not absolutely necessary to treat, if that aren't catchy, etc.)
4. Of course you should feel relief! HSV1 antibodies mean very little--just that you, along with lots of other people, were once exposed to the cold sore virus somewhere along the line.
Best.
