Test Overview: The Herpes Simplex Virus Type 2 (HSV-2) IgG test detects IgG antibodies against HSV-2 in the blood. It helps determine whether a person has had a past or established HSV-2 infection, which is commonly associated with genital herpes.
Why This Test is Done:
Detect previous exposure to HSV-2
Support diagnosis of genital herpes infection
Evaluate individuals with recurrent genital sores
Screen high-risk individuals when clinically indicated
Assess HSV status during pregnancy when recommended by a healthcare provider
Symptoms That May Require Testing:
Painful blisters or ulcers in the genital area
Itching, burning, or tingling sensations
Pain during urination
Recurrent genital lesions
Exposure to a partner diagnosed with herpes
Benefits:
Identifies past HSV-2 infection
Helps distinguish HSV-2 exposure from active symptoms when combined with clinical evaluation
Supports appropriate medical counseling and management
Useful in assessing transmission risk
Preparation:
No fasting or special preparation is required.
Normal Result:
Negative: No detectable HSV-2 IgG antibodies.
Positive: Indicates previous exposure or established HSV-2 infection. A positive result does not necessarily indicate a current active outbreak and should be interpreted along with symptoms and clinical findings.
Who Should Consider This Test?
Individuals with symptoms suggestive of genital herpes
Those with a partner diagnosed with HSV-2
People with recurrent genital lesions
Individuals advised by their healthcare provider for STI evaluation
Pregnant women when clinically indicated
Note: HSV-2 IgG antibodies may take several weeks to develop after initial infection. If recent exposure is suspected and the result is negative, your healthcare provider may recommend repeat testing after the appropriate window period.
