About half the population in the US has HSV 1 infection, the cause of cold sores.  Have you ever in your life had a cold sore on your lip?  If yes, then that's why you test positive.  If this is a concern for you, then you may wish to obtain an IgG test that gives you an index value, that would be through Quest or LabCorp.  But the igG test for HSV 1 also misses 30% of infections so beware of a negative.

Yes, it does.  They come across my desk daily with index values.  I have no idea why they would say that.  I also know that LabCorp does.  But the best antibody test is the western blot - spendy but very accurate and done only at the University of Washington.  Your own provider can help you obtain that or I can help you at westoverheights.com.  You can call UW at 206-685-6066 and get the necessary kit sent to your home.  You could also try doing it at labCorp
