Description
Why It’s Done:
This test is commonly ordered to:
• Determine prior exposure to HSV-1, especially in asymptomatic individuals.
• Distinguish between HSV-1 and HSV-2 infections, which is important for diagnosis and management.
• Evaluate patients with a history of herpes-like symptoms, even if they are not currently experiencing an outbreak.
• Screen individuals during pregnancy, as herpes infections can pose a risk to newborns.
• Identify silent carriers of the virus to help prevent transmission.
A positive HSV-1 IgG result means a person has been infected at some point in the past, even if they never showed symptoms.
Preparation:
• No fasting or special preparation is required.
• A simple blood sample is drawn from a vein in your arm.
• Inform your doctor if you have:
o Any history of herpes symptoms (oral or genital).
o Recently had blisters, sores, or flu-like symptoms.
o Concerns about herpes transmission or sexual health.
