Herpes Simplex Virus 1 and 2 (IgG), with Reflex to HSV-2 Inhibition - Herpes Simplex Virus (HSV) is responsible for several clinically significant human viral diseases, with severity ranging from inapparent to fatal. Clinical manifestations include genital tract infections, neonatal herpes, meningoencephalitis, keratoconjunctivitis, and gingivostomatitis. There are two HSV serotypes that are closely related antigenically. HSV type 2 is more commonly associated with genital tract and neonatal infections, while HSV type 1 is more commonly associated with infections of non-genital sites. Specific typing is not usually required for diagnosis or treatment. The mean time to seroconversion using the type specific assay is 25 days. The performance of this assay has not been established for use in a pediatric population, for neonatal screening, or for testing of immunocompromised patients.
This assay utilizes recombinant type-specific antigens to differentiate HSV-1 from HSV-2 infections. A index positive result cannot distinguish between recent and past infection. If recent HSV infection is suspected but the results are negative or equivocal, the assay should be repeated in 4-6 weeks.
HSV 1 IgG, Type Specific Ab
HSV 2 IgG, Type Specific Ab
If Herpes Simplex Virus 2 (IgG) is >1.09, then HSV-2 Inhibition Study will be performed
No fasting required.
Estimated turnaround for results is 3 business days. If confirmation testing is required, the estimated time may be extended.
