Should I ask to be retested in case it was false positive?

Back in October I was told my blood test came back positive for HSV2. I’ve never had any sort of symptoms, and so that came as a really big shock as I also haven’t been with very many people at all.

He said it could possibly be incorrect and there’s no way to be absolutely sure as I’ve never had a “outbreak” or anything. I’m nervous. Any advice?
