The Herpes Simplex Virus 1 (IgG), Type-Specific Antibo test contains 1 test with 1 biomarker.
Herpes Simplex Virus 1 (IgG), Type-Specific Antibody (HerpeSelect®)
Tests for HSV 1 IGG, TYPE SPECIFIC AB to diagnose HSV-1 infection when lesions are absent. A positive HSV-1 IgG antibody test indicates a previous infection.
- <0.90 Negative
- 0.90-1.09 Equivocal
- >1.09 Positive
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. The performance index characteristics of the assay have not been established for pediatric populations, immunocompromised patients, or neonatal screening.
Individuals infected with HSV may not exhibit detectable IgG antibody in the early stages of infection.
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.
