No, actually a higher number usually means that you've had it for longer, but a few things - was this on an IgG test? When was your last possible exposure? Why did you test?
Your GP will tell you that you have it, and you might - it's a good possibility, a really good one. Technically, anything over a 3.5 is a true positive and doesn't need to be confirmed.
Terri Warren, a herpes expert who works with people to get confirmatory Western Blot tests done, has seen false positives into the teens. It's far less common to have a false positive when your numbers are higher, of course, but without symptoms, it's reasonable to want to confirm it.
Your doctor can order a Western Blot test, but please prepare yourself that they won't. A lot of docs don't even know about it. You can also go through Terri Warren to get one, but you'll have to self-pay. It's expensive.

I don't want to get your hopes up. Chances are good that you have hsv2. Many people have it and never get symptoms. Do you also have hsv1?
If you do have it, life as you know it is not over. It will be a little bit altered, maybe, but you'll be okay, I promise.
