Variable: Both igm and igg can be present concurrently. Igm response may appear about a week after exposure and may last a few months. Igg is likely to appear about two after after exposure and be present life long.

3 weeks: Approximately 50% of people will have igg antibodies detectable by 3 weeks. Most people will have igg detectable by 3-4 months and occasionally it may take up to 6 months.

Prior exposure: Most adults have been exposed to HSV 1, oral herpes. HSV 2 or genital herpes is less common. Was the IgG antibody result for HSV 1 or 2?

A 32-year-old female asked:
Most doctors say that it takes between 4-8 weeks for antibodies for HSV 1/2 to show up in blood. Is this for IgG or IgM antibodies?
Dr. Gurmukh Singhanswered
Pathology 51 years experience
IgM antibodies come: About a week before igg antibodies. Hsv may be diagnosed by viral culture and/or microscopic examination of scrapings from a lesion.
