I have many false positives on the supplemental test from LabCorp (positive supplemental, negative western blot). However, your 4.36 is a little higher than most false positives, but I’ve definitely seen false positives in this range. It is not equivocal, it is positive. And your HSV 1 is not equivocal, it is negative.
Your partners cold sores were more likely HSV 1.
If you were my patient, I would order the western blot for confirmation of this index value.
