I’m totally with you that a positive IgM is virtually meaningless. I can’t tell you how many people I have seen who have positive IgM tests, erroneously ordered, who negative have a positive IgG test. The IgM is not wrong every single time but it is wrong most of the time, based on my clinic experience. The problem is that when it is drawn, it is hard to know when it might be positive. However, your value is incredibly low and I’m assuming that you have no symptoms to be concerned about or you would have mentioned that. In addition, it is a combined HSV 1 and 2, and we know that IgM’s intermittently go up and down with HSV 1 and 2 infection so who knows what the heck this means???
If you were my patient, I would do a final IgG at 12 weeks and forget it. Really
