So at about 13 weeks, the IgG misses about 8% of HSV 2 and 30% of HSV 1, compared to the western blot. I doubt that testing with the IgG again at 16 weeks will add useful information. If you want a better test, yes, do the western blot. I would actually encourage this since you had sores that lasted two weeks in the genital area.
