The first clinical episode of genital herpes varies from a severe infection characterised by extensive, painful genital and perigenital ulceration and systemic symptoms to a mild infection with minimal localised vesiculation and ulceration. Drawbacks include the low sensitivity and NPV, lack of availability, IgM antibodies may occasionally be produced in response to recurrent infection and, finally, IgM antibodies may take up to 10 days to develop and last 7–10 days.

The specificity and PPV of HSV IgM was 100% the sensitivity was 79% and the NPV 85%.Ĭonclusion: IgM HSV serology may be useful in the management of some patients with first episode genital herpes and provide an indication of the source of infection. 23 (18.3%) had primary genital herpes, 34 (27.0%) non-primary first episode, and 69 (54.8%) had pre-existing genital herpes. Therefore, 126 patients were included in the analysis. 31 were excluded (missing data or no detectable antibodies and negative viral isolation). HSV-1 IgG and IgM and HSV-2 IgM antibodies were detected using western blot. Equivocal results were resolved by western blot. Sera were tested for IgG antibodies to HSV-2 using an indirect enzyme linked immunosorbent assay (ELISA).

Methods: Patients with a first clinical episode of genital herpes were recruited. Objective: To evaluate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of HSV-1 and HSV-2 IgM antibodies for the diagnosis of first episode genital herpes, when compared with clinical diagnosis. The use of IgM to classify first episode genital herpes has not been evaluated. Background: First episode genital herpes simplex virus (HSV) infections can be classified into three groups, primary genital herpes (no previous exposure to HSV), non-primary first episode (IgG antibody to HSV of the non-presenting type), and first episode with pre-existing IgG HSV antibodies.
