Test Details


Use

Detect IgG antibodies specific to HSV type 2 infection; confirm or rule out possible infection with herpes simplex type 2 virus in prenatal patients in whom HSV 2 infection can cause serious prenatal disease. Per CDC guidelines, specimens with equivocal or low positive results for HSV-2 type specific IgG will reflex for supplemental testing by another assay.

In a patient with no history of lesion disease, a positive result for this test may be indicative that the primary infection was asymptomatic. The magnitude of the Index Value is not indicative of the amount of antibody present in the patient sample. Once infected by HSV, it is possible for a patient to shed virus without the development of lesions (asymptomatic shedding). This test does not indicate the site of HSV infection. There is a considerable homology between HSV-1 and HSV-2 antigens, so that antibodies formed against either virus are highly cross-reactive. This assay is based on glycoprotein G-2, purified from HSV-2 infected cells, and is specific for type 2 antibodies.

HSV-2 IgG Type Specific

HSV-2 IgG Supplemental

Interpretation

Positive / Equivocal

Positive

Indicates the presence of detectable IgG antibodies to HSV-2.

Positive / Equivocal

Negative

Unable to confirm the presence of IgG antibodies to HSV-2. Recommend retesting in 2 to 4 weeks.


Limitations

This test is intended for qualitative determination only. The magnitude of the Index Value is not indicative of the amount of antibody present in the patient sample.


Methodology

Chemiluminescent immunoassay (CLIA). Reflex of specimens equivocal and low positive for HSV-2 type specific IgG to a membrane based immunoassay.


Additional Information

Set up Monday thru Friday.
