This type-specific blood test looks for antibodies against both herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2). HSV-1 typically causes oral herpes, while HSV-2 typically causes genital herpes, but both can affect either area. Testing both types together helps clarify which virus a person has been exposed to and supports informed discussions about symptoms and transmission. Reporting each type separately supports clearer counseling about oral and genital herpes.

• HSV-1-specific IgG antibodies Antibodies produced in response to herpes simplex virus type 1.
• HSV-2-specific IgG antibodies Antibodies produced in response to herpes simplex virus type 2.

• You have oral or genital symptoms a clinician wants to evaluate.
• You had possible exposure to herpes and want to know which type is involved.
• A partner has HSV-1 or HSV-2 and you want to check your status.
• You are being screened for sexually transmitted infections that include herpes.

• No fasting is required for this blood test.
• The sample can be collected at any time of day.
• Report any antiviral medications you take.
• Tell the clinician about any prior outbreaks or known herpes diagnosis.

Results are reported for HSV-1 and HSV-2 separately. A positive result for either type may indicate that the virus is present, while negative results suggest no evidence of antibodies to that type at the time of testing. Because antibodies can take weeks to develop, an early sample may be falsely negative. The test does not show when infection occurred or predict outbreak frequency. Discuss both results with a healthcare provider.
