Order Genital Herpes (HSV-2) Blood TestThe HSV-2 (Genital Herpes) Blood Test is a serologic assay that detects antibodies specific to herpes simplex virus type 2. Unlike direct viral detection methods, this test identifies the immune system's response to HSV-2, making it useful for diagnosing past or present infection even when no symptoms are present. The HerpeSelect® test is a widely used enzyme-linked immunosorbent assay (ELISA) that targets IgG antibodies against HSV-2. Because antibodies take time to develop after exposure, the test is most reliable when performed at least several weeks after potential transmission. This blood test does not require a lesion swab and can be performed regardless of active outbreaks. It is important to note that HSV-2 primarily causes genital herpes, but the virus can also infect other mucosal surfaces. A positive result indicates exposure to HSV-2, not necessarily active disease, as the virus can remain latent. Confirmatory testing may be recommended for certain low-prevalence populations to rule out false positives. The test is not intended for screening asymptomatic individuals without risk factors, and it does not distinguish between oral and genital infections. Interpretation should always be done in consultation with a healthcare provider, who can correlate results with clinical history and symptoms.
About Genital Herpes (HSV-2) Blood Test in Big Spring
The HSV-2 blood test detects IgG antibodies produced in response to herpes simplex virus type 2.
Herpes simplex virus type 2 (HSV-2) is a double-stranded DNA virus belonging to the Herpesviridae family. It is the primary cause of genital herpes, a chronic viral infection that can present with recurrent painful blisters or ulcers in the genital or anal area. However, many individuals with HSV-2 are asymptomatic or have unrecognized mild symptoms, making serologic testing a key tool for identifying infection.
The HerpeSelect® test is an enzyme-linked immunosorbent assay (ELISA) that qualitatively detects IgG antibodies specific to HSV-2 in serum or plasma. After initial exposure, the immune system typically produces IgM antibodies first, followed by IgG antibodies that persist for life. IgG antibodies usually become detectable within several weeks to a few months after infection. The test does not differentiate between recent and remote infection, nor does it indicate whether the virus is actively shedding.
Because HSV-1 and HSV-2 share significant genetic homology, early serologic tests had cross-reactivity issues. The HerpeSelect® assay uses a type-specific glycoprotein G2 (gG2) antigen, which improves specificity for HSV-2. Nevertheless, false-positive results can occur, especially in populations with low HSV-2 prevalence. In such cases, a second confirmatory test, such as the Western blot or a different ELISA, may be advised. The test is not intended for use in individuals under a certain age without clinical justification, and it should not be used to screen the general population.
