Description
Why It’s Done:
The HSV I & II IgM test is ordered to:
• Diagnose a recent or primary HSV infection, especially when symptoms are present (e.g., sores, blisters, fever).
• Evaluate individuals with new or unexplained herpes-like symptoms.
• Test pregnant women suspected of a recent herpes infection to assess the risk to the baby.
• Assess neonatal herpes or suspected herpes infection in infants.
• Investigate acute infections in immunocompromised patients.
Note: For determining a past infection, an HSV IgG test is more appropriate.
Preparation:
• No fasting is required.
• No special preparation is needed.
• Inform your healthcare provider if you are:
o Taking any antiviral medications.
o Experiencing symptoms such as sores, itching, or fever.
o Recently exposed to someone with known herpes infection
