🧪 What is HSV I & II – IgG?
The HSV I & II – IgG test is a serological blood test that detects IgG antibodies specific to:
- HSV-1: Commonly causes oral herpes (cold sores)
- HSV-2: Primarily causes genital herpes
The presence of IgG antibodies indicates past exposure or latent infection with the Herpes Simplex Virus.
❓ Why is the Test Done?
To:
- Determine past or latent HSV infection
- Differentiate between HSV-1 and HSV-2 infections
- Screen individuals with recurrent sores or ulcers
- Assess asymptomatic sexual partners or during pregnancy
- Guide prenatal counseling to prevent neonatal herpes
📊 Normal Range / Reference Values
Result | Interpretation |
|---|---|
Negative / Not Detected | No evidence of prior exposure |
Positive / Detected | Past or latent HSV infection present |
Equivocal | Borderline result – repeat test recommended in 2–4 weeks |
Units are typically reported as an Index Value, and cutoff values may vary by lab.
📈 Interpretation of Results
Test Result | Meaning |
|---|---|
HSV-1 IgG Positive | Previous exposure to HSV-1 (often oral) |
HSV-2 IgG Positive | Previous exposure to HSV-2 (usually genital) |
Both Positive | Exposure to both HSV-1 and HSV-2 |
Both Negative | No prior exposure; susceptible to infection |
Recent infection suspicion? | Consider HSV IgM or PCR swab of active lesions |
