- Determine exposure to HSV-2
- Support screening in high-risk individuals
- Assist in clinical evaluation.
ANTI-HERPES SIMPLEX VIRUS 2 IGG Test Purpose
The Anti-Herpes Simplex Virus Type 2 (HSV-2) IgG Test measures IgG antibodies against Herpes Simplex Virus Type 2 (HSV-2) in the blood. HSV-2 is the virus most commonly associated with genital herpes, a sexually transmitted infection (STI) that can cause painful blisters or sores in the genital or anal area. Once infected, the virus remains in the body for life and may reactivate periodically, even when no symptoms are present.
Healthcare providers commonly recommend this test for individuals with a history of genital sores, suspected previous HSV-2 infection, or those who have had sexual contact with a partner diagnosed with genital herpes. The presence of HSV-2 IgG antibodies generally indicates past exposure or previous infection, even in individuals who have never experienced noticeable symptoms.
Furthermore, the HSV-2 IgG Test helps distinguish past infection from a recent infection when interpreted together with the HSV-2 IgM Test, clinical findings, and other laboratory investigations. It is also useful for evaluating individuals at higher risk of sexually transmitted infections, screening sexual partners of infected individuals, and assessing previous HSV-2 exposure before pregnancy or in people with weakened immune systems when clinically indicated.
The HSV-2 IgG Test is often performed alongside HSV-1 IgG, HSV IgM, or HSV PCR from lesion samples to provide a comprehensive evaluation of herpes simplex virus infections.

FAQs
1. What is the Anti-HSV-2 IgG Test used for?
The Anti-HSV-2 IgG Test detects IgG antibodies against Herpes Simplex Virus Type 2. It helps determine whether a person has had a previous HSV-2 infection and has developed antibodies against the virus.
2. Do I need to fast before the HSV-2 IgG Test?
No. Fasting is generally not required for this blood test. However, always follow any specific instructions provided by your healthcare provider before sample collection.
3. What does a positive HSV-2 IgG result mean?
A positive HSV-2 IgG result indicates past exposure or previous infection with Herpes Simplex Virus Type 2. It does not necessarily mean that you have an active infection or current symptoms. Your healthcare provider will interpret the result together with your clinical history, symptoms, and, if necessary, additional tests such as HSV-2 IgM or HSV PCR to determine the appropriate diagnosis and management.
