Description
Why It’s Done:
The HSV I & II IgG test is performed to:
• Determine if a person has been previously infected with HSV-1 or HSV-2.
• Help diagnose asymptomatic HSV infections.
• Evaluate recurrent symptoms such as genital sores, oral lesions, or neurological issues.
• Assess exposure in pregnant women, to reduce risk of neonatal herpes.
• Screen individuals with a partner known to have herpes.
This test is especially useful for people who may not show visible symptoms but are concerned about prior exposure.
Preparation:
• No special preparation is required.
• A blood sample will be drawn from a vein, usually from the arm.
• Inform your doctor about any ongoing infections or recent vaccinations, if applicable.
