Western blot test is reliable and confirmatory test for HSV2.
And as per your description,it indicates the evidence of past infection so possibly it's IgG HSV2 positive.
Many people can test positive for HSV2 (genital herpes) and never have symptoms. Some people, after exposure, will have a breakout within 2 weeks after the virus is transmitted but some only will exhibit flu-like symptoms including fever and swollen glands.
Sometimes the outbreak is so mild that it gets unnoticed.
The presence of IgG for HSV-2 without any history of outbreak suggest prior exposure but your immune system was able to overcome and suppress it from showing symptoms.
HSV-2 IgG are antibodies that the body make to fight infections due to HSV.
If you have active infection due to HSV-2, then you will have IgM and IgG antibodies , or IgM alone.
A positive HSV 2 IgG suggest a past exposure to HSV 2.
The virus is now dormant and can activate if the immune system is down as in events of stress or illness.
Hope this helps.
