Welcome to the forum. I agree there is a good chance you don't have HSV-2, despite the apparently positive test result. The identical quesiton has been addressed several times on this forum. For example, please see http://www.medhelp.org/posts/show/593272
First, terminology: There is no such thing as a test showing someone is "exposed" but not infected. A positive blood test means someone is infected with HSV-2, not just exposed. Even if such persons have no symptoms, they can get future outbreaks and can transmit HSV-2 to their sex partners.
Since the type-specific HSV IgG tests came into general use, research has shown that results above 1.1 (the official cut-off value for a positive result) are not reliably positive unless 3.5 or higher. At values like your result of 1.7, only around 30-40% actually have HSV-2. As you will see in the other thread, the fact that your HSV-1 result is positive is in your favor: it might increase the chance that your HSV-2 result is falsely positive.
The other thread also describes how you can sort this out by additional testing, either with the BiokitUSA test (which your doctor can do in the office in 20 minutes, while you wait) or by the Western blot test.
Don't blame your doctor (too much) for not being aware of proper interpretation of the HSV blood tests. It's complex, and it's certainly confusing -- for reasons explained in the other thread. You might print out both this reply and the other thread and discuss them with your doctor.
Bottom line: It is possible you have HSV-2, but probably you don't. Most likely repeat testing will sort it out.
