Why This Test Is Done

Your healthcare provider may recommend this test if you have a new or recurring skin lesion that could be caused by HSV-2. It helps confirm whether the virus is active in the lesion rather than just past exposure.

What to Expect During the Test

A small sample of fluid is collected from your active skin lesion using a swab. This is a quick, painless procedure and does not require any special preparation.

How the Results Are Interpreted

Positive results indicate the presence of HSV-2 antibodies in the lesion, suggesting an active infection. Negative results mean the test did not detect HSV-2 antibodies in this sample. Results should be interpreted by your healthcare provider in the context of your symptoms and medical history.

Clinical Significance

Identifying HSV-2 infection in a skin lesion is crucial for managing symptoms, preventing spread to others, and guiding treatment decisions. Early diagnosis can help reduce discomfort and complications.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test is primarily used to confirm active HSV-2 infection in skin lesions rather than detecting past exposure. It is not a routine screening test for HSV-2 in asymptomatic individuals.

Short name

HSV-2 Antibody (Skin)

A positive result means the test detected antibodies to HSV-2 in your skin lesion, indicating an active infection. This confirms the presence of the virus in the lesion and may guide treatment options to manage symptoms and prevent spread.
