Herpes Simplex Virus Type 1 Antibody, Qualitative (IgG) by Probe-Based Immunoassay

What Does This Test Measure?

The test measures the presence of IgG antibodies against HSV-1. These antibodies develop after your body has been exposed to the virus, usually months or years after initial infection. This is a qualitative test, meaning it only tells you whether antibodies are present or not, rather than how much.

Why Might You Need This Test?

Doctors may order this test if you have a history of cold sores or other HSV-1-related symptoms, if you have concerns about recurrent infections, or if you are planning a pregnancy and need to assess potential risks. It can also be used in certain research or screening contexts.

How Is the Test Performed?

A blood sample is drawn from a vein in your arm. The sample is then processed and tested using a probe-based immunoassay, which detects specific antibodies in your blood. Results are typically available within a few days.

What Are Possible Results?

The test result will be either positive (indicating the presence of HSV-1 antibodies) or negative (indicating no detectable antibodies). A positive result suggests past exposure to HSV-1, but does not confirm an active infection.
