Herpes Simplex 2 IgG (HSV-2)

What Is the HSV-2 IgG Test?

The HSV-2 IgG test is a blood test used to detect antibodies to herpes simplex virus type 2 (HSV-2), the virus responsible for genital herpes. This test helps determine whether a person has ever been exposed to HSV-2, indicating either a current or past infection.

How the HSV-2 IgG Test Works

The test identifies the presence of immunoglobulin G (IgG) antibodies in the blood. These antibodies are produced by the immune system in response to HSV-2 infection. Once formed, IgG antibodies can remain in the bloodstream for years, even after the virus becomes inactive or dormant.

Identifying Past or Ongoing Infections

Unlike the HSV-2 IgM test, which is used to detect recent infections, the IgG test reveals whether the body has mounted an immune response at any point in the past. This makes it a valuable tool for individuals who may have had asymptomatic infections or are unsure about their exposure history.

Additional Testing and Symptom Assessment

In cases where a person suspects genital herpes—especially if they are experiencing symptoms such as painful genital sores or blisters—healthcare professionals in Slough may recommend further testing. These include:

Viral culture

PCR (Polymerase Chain Reaction) testing

Clinical examination of visible symptoms

These methods are often used alongside HSV-2 IgG testing to confirm the diagnosis and guide treatment options.
