Herpes Screening: Understanding Testing Methods & Diagnostics

Herpes simplex virus (HSV) screening

* Serology: HSV serology is the most common method for detecting herpes infection. It involves testing a blood sample for the presence of antibodies to HSV.

* HSV-1: IgG antibodies indicate past infection with HSV-1.

* HSV-2: IgG antibodies indicate past infection with HSV-2.

* IgM antibodies indicate recent infection with HSV.

* Viral culture: Viral culture is the gold standard for diagnosing herpes infection. It involves collecting a sample of fluid from the affected area and growing the virus in the laboratory.

* PCR (polymerase chain reaction): PCR is a molecular test that can detect the DNA of HSV in a sample of fluid or tissue.

* Direct fluorescent antibody (DFA) test: The DFA test is a rapid test that can detect the presence of HSV antigens in a sample of fluid or tissue.

Herpes zoster virus (VZV) screening

* Serology: VZV serology is the most common method for detecting VZV infection. It involves testing a blood sample for the presence of antibodies to VZV.

* IgG antibodies indicate past infection with VZV.

* IgM antibodies indicate recent infection with VZV.

* Viral culture: Viral culture is the gold standard for diagnosing VZV infection. It involves collecting a sample of fluid from the affected area and growing the virus in the laboratory.

* PCR (polymerase chain reaction): PCR is a molecular test that can detect the DNA of VZV in a sample of fluid or tissue.

* Direct fluorescent antibody (DFA) test: The DFA test is a rapid test that can detect the presence of VZV antigens in a sample of fluid or tissue.
