If you were my patient, I would swab test this for herpes yes. Having said that, I think it is more likely from a change in weather or it could be angular chelitis. The thing is, if the antibody test is negative for HSV 1, it is certain with about an 80-90% accuracy but that’s not great. A western blot is better for HSV 1. So in terms of answering the accuracy at 8 weeks, you need to take into account the lack of sensitivity of the test for HSV 1, so I guess I can’t really answer that for you. The lack of sensitivity of the screening test applies to both of you.
Not everyone who gets a new infection has symptoms right away so it isn’t impossible that you could have acquired this years ago and just having symptoms. I just can’t say! You need lab testing
