Herpes Simplex Virus Type 2 Immunoglobulin G (IgG) Antibody, Quantitative

What Does This Test Measure?

The test detects IgG antibodies specific to HSV-2. These antibodies develop after an initial infection and can remain in your system for years, indicating past exposure. IgG antibodies are not typically used to diagnose an active infection but can be useful in certain clinical scenarios, such as evaluating exposure history or assessing immune response in research or specific clinical contexts.

Why Might You Need This Test?

A HSV-2 IgG antibody test may be ordered if you have concerns about past exposure to HSV-2, such as in research studies, occupational health assessments, or when evaluating immune responses in specific medical conditions. It is not typically used for diagnosing active herpes outbreaks, which are usually managed with viral culture or other diagnostic tests.

How Is the Test Performed?

A blood sample is drawn from a vein in your arm. The blood is then processed to separate the serum, which is sent to a laboratory for analysis using a fluorescence immunoassay (FIA). This method detects the presence of HSV-2-specific IgG antibodies with high sensitivity and specificity.

What Are the Possible Results?

The test result will indicate whether detectable levels of HSV-2 IgG antibodies are present. A positive result suggests past exposure to HSV-2, but it does not confirm whether you currently have an active infection. Interpretation of results should always be done by your healthcare provider, who will consider your medical history and other clinical factors.
