Is blood pcr test accurate for hsv? i don't have any symptoms nor lesions or blisters on my genitals. i tested <0.9 igg & 1.5+ igm a week ago. help?

HSV: Pcr would detect the viral level in the blood stream, but you have no symptom, a pcr would not be of any use, antibodies to hsv only mean post expousre to hsv.

You misunderstand HSV diagnosis. If a doctor ordered these tests, so does s/he. PCR isn't used to diagnose new HSV infection. The IgM HSV test is useless, never done by STI/herpes experts; your weakly positive IgM result means nothing. The IgG test is useful only 90+ days after the last exposure. Also, testing works differently for HSV1 vs HSV2. If no symptoms, probably no need for any test.
