HSV-2 IgG Antibodies
HSV-2 IgG antibodies are a measure that reflects the immune system’s response to Herpes Simplex Virus type 2 (HSV-2), the virus most commonly associated with genital herpes. These antibodies indicate prior exposure to HSV-2, even if no symptoms were experienced. They typically develop within several weeks after infection and remain present long-term. The test detects whether an individual has been infected at some point but cannot determine the timing of infection or whether the virus is currently active.
Description
Who would benefit from testing HSV-2 IgG antibodies?
Testing for HSV-2 IgG antibodies is recommended for individuals with recurrent genital symptoms, those with new sexual partners, or during pregnancy to assess transmission risk. It’s also relevant for people undergoing IVF or immunosuppressive therapy, where latent infections can affect outcomes.
What are symptoms of HSV-2 infection?
- Painful genital sores or blisters
- Itching or burning in the genital area
- Flu-like symptoms during the first outbreak
- Painful urination
- Swollen lymph nodes
- Nerve pain or discomfort in the pelvic region
How is HSV-2 transmitted?
HSV-2 is primarily transmitted through sexual contact, including genital-genital, oral-genital, or anal-genital contact. The virus can be spread even when symptoms are not present, through asymptomatic viral shedding.
What does a positive HSV-2 IgG result mean?
A positive result means the immune system has developed antibodies against HSV-2, indicating previous infection. It does not reflect current infectivity or activity level, but it confirms that the virus is present in the body and may be intermittently contagious.
