I seriously doubt that you acquired HSV 1 from a kiss. Since you’ve reported cold sores in the past, I think the first test simply missed the HSV 1 or reported it at a far lower level than was actually correct.
The University of Washington recommends that if you have two indeterminate western blots, at least 3 months apart, that you stop testing and consider this a very likely negative. There is no CDC guidance on this.
