Herpes diagnosis by blood test isn't quite as simple as just knowing "postive" versus "negative" results. If you use the search link to look for threads with the terms "herpes diagnosis" or "HerpeSelect" (the most commonly used blood test), you will find innumerable discussions about the details.
But assuming your test is indeed positive, you definitely are infected with HSV-2, even if you have no symptoms of genital herpes. However, most people with positive blood tests come to recognize recurrent genital outbreaks that they previously missed, because they were mild or atypical. So keep up your awareness in the coming months.
It takes up to 3-4 months for the most commonly used HSV blood tests to become positive. So if your partner's HSV-2 test is negative, it might be necessary for her to be retested to be certain. However, to answer your question directly: If her HSV-2 test indeed is negative at least 3-4 months after the last possible exposure, then she definitely was not infected -- that would mean that her health was not "compromised" in any way (leaving aside the potential for other STDs).
The best thing for the two of you is to wait for her test result, then go together for an in-person evaluation by a herpes knowledgeable health care provider. If uncertain about whether your doctor or hers is up to speed on herpes, your local health department STD clinic may be a good bet. Or you can contact the American Social Health Association (www.ashastd.org) and see if they can recommend a provider in your area. ASHA also has excellent general information about genital herpes.
I hope this helps. Best wishes--- HHH, MD
