Why did you take another HSV1 test? I'm not sure which test was first, but both are clearly positive, so I'm not sure why you took another test?
There really isn't any difference. I've had herpes for about 15 years. I could test today, and my result could be 19.2. Tomorrow, it might be 38.4, and the following day, it could be 25.4. It means nothing except I'm positive.
There is never a 0.0 result. Even if you are negative, you might be .08 one day, and .6 the next. It's all still negative.
Some people do show an increase in antibodies during an outbreak, so that can affect it, as well.
Is there a specific reason you tested? Did you have a specific question you were looking to have answered, like can you tell if this is a new infection? (You can't, unless you've had a negative result in the past and now have a positive result.)
