Herpes Simplex 2 IgM (HSV-2) LIS Code: HSV-2 IgM

What Is the HSV-2 IgM Test?

The HSV-2 IgM test is a blood test used to detect immunoglobulin M (IgM) antibodies produced in response to herpes simplex virus type 2 (HSV-2), the virus responsible for genital herpes. This test helps identify recent or initial infections, making it useful for early diagnosis.

Role of IgM Antibodies in HSV-2 Detection

IgM antibodies are among the first to appear in the bloodstream after a new infection. In the case of HSV-2, these antibodies typically become detectable within 2 to 3 weeks of initial exposure and may remain in the body for several weeks to a few months.

Difference Between HSV-2 IgM and IgG Testing

While the HSV-2 IgG test can indicate both past and current infections, the HSV-2 IgM test is more specific to recent infections. It is often recommended when a patient shows early symptoms of genital herpes or has had recent exposure.

Additional Diagnostic Methods for Genital Herpes

If HSV-2 is suspected, especially in symptomatic individuals, healthcare professionals in Slough may also perform:

Viral culture testing

Polymerase Chain Reaction (PCR) test

Physical examination for symptoms such as painful genital sores, ulcers, or blisters

These methods, alongside IgM testing, help confirm the diagnosis and guide appropriate treatment.
