HSV I Antibody IgG

HSV I ANTIBODY IGG Test

The HSV I Antibody IgG test detects IgG antibodies against Herpes Simplex Virus Type 1 (HSV-1) in the blood. HSV-1 commonly causes oral herpes, including cold sores around the mouth, but it can also cause genital infection.

IgG antibodies usually develop after exposure to the virus and may remain detectable for a long time. Therefore, a positive HSV-1 IgG result generally indicates previous or established exposure to HSV-1. However, the test cannot determine exactly when the infection occurred or whether the virus is currently active.

If a person has active blisters, sores, or lesions, a healthcare provider may recommend a PCR or other direct test from the lesion, as this can provide more information about a current infection.

This Test is Recommended for Individuals:

• Individuals with a history of cold sores or oral blisters
• People with symptoms suggestive of HSV-1 infection
• Individuals being evaluated for possible herpes infection
• People with a partner who has known HSV infection, when testing is clinically appropriate
• Individuals who need to determine whether they have previously been exposed to HSV-1
• Pregnant individuals when HSV testing is specifically recommended by their healthcare provider

FAQs

1. What does a positive HSV-1 IgG result mean?
A positive result generally means that HSV-1 antibodies are present, indicating previous or established exposure to HSV-1. It does not necessarily mean that an active outbreak is occurring.

2. Does HSV-1 IgG tell when I contracted the infection?
No. The test cannot determine the exact timing of infection. IgG antibodies can remain detectable long after the initial infection.

3. Can HSV-1 IgG detect an active herpes outbreak?
Not directly. HSV-1 IgG measures antibodies rather than the virus itself. If active sores or blisters are present, your healthcare provider may recommend HSV PCR testing from the lesion for evaluation of current infection.
