The problem for so many years, is that
the older tests (which are still commonly used) can't determine which type you may have, so if you suffer from cold sores
(which is almost always HSV I), that
means the results will come back positive but they won't
be able to tell you for which strain, or for that
matter, if you might have both HSV I & II. not
to mention, it can take anywhere from 4 - 16 weeks I believe, before the HSV antibodies will appear in blood work...
