Frequently Asked Questions
What does IgG testing tell me?
IgG antibodies indicate past infection with HSV-1 and/or HSV-2. The test can distinguish between the two types and shows whether you've been exposed, even if you've never had symptoms.
How accurate is the IgG test?
The type-specific IgG test is highly accurate with 98%+ sensitivity and specificity. However, it takes 12-16 weeks after infection for antibodies to develop, so recent infections may not be detected.
Can I have herpes without symptoms?
Yes, many people with HSV-1 or HSV-2 never develop noticeable symptoms. The IgG test can detect past infection regardless of whether you've had symptoms.
