Herpes is a viral infection that is caused by the herpes simplex virus (HSV). There are two main kinds of HSV viruses, namely - HSV-1 and HSV-2. HSV Antibodies are associated with diseases caused by Herpes. This HSV-1- IgG Antibody test, measures the levels of viral antibodies and thus helps to detect herpes infection.

Why HSV - 1 (IgG)- CSF Test?


Herpes simplex virus (HSV) is a virus that produced viral infections in human beings and it belongs to Herpesviridae family. The viron structure of this herpes virus consists of a relatively large, double-stranded DNA genome encased within the caspid, wrapped in a lipid bi-layer called an envelop. Two types of Herpes simplex virus predominantly infect the human population (shedding the virus), namely Human alphaherpesvirus-1(HSV-1, caused mainly contracted by flu from an infected person by sneezing (but also through other modes of transmission) and Human alphaherpesvirus-2 (HSV-2, is a sexually transmitted disease mainly transmitted by sexual contact). Moreover, the transmission of this virus can also occur by vertical transmission (i.e from an infected pregnant mother to the child). Both HSV-1 (produces cold sores) and HSV-2 (causes genital herpes) are common and are highly contagious. The mechanism of action of HSV infection is initially sporadic and on an episode of re-activation (latent infection in neural ganglia i.e trigeminal ganglia) is neurotropic and neuro-invasive mode – via axon of the neuron (the virus persists in the body by hiding from the immune system in the cell bodies of neurons). Symptoms of HSV infection are asymptomatic but also can exhibit certain definite clinical manifestations, which include tingling or itching or burning on the skin, fever, headaches, body aches, swollen lymph nodes, watery painful blisters in the skin or mucus membranes of the mouth, lips, nose and/or genitals, buttocks, anus, etc, but also atypically it can present with manifestations particularly in the ocular/eye or blisters in the ear, meningitis, seizures (due to spread/ dissemination of the virus in the body), etc. The purpose of screening test for herpes is to identify evidence of an HSV infection, such as confirming a diagnosis of HSV infection with oral sore and/or genital sores (to differentiate HSV-1 from HSV-2), suspected pregnant women (HSV is a part of antenatal diagnosis i.e among the TORCH infections – They are a group of congenital infections that may be transmitted from mother to child due to infection), babies born to a mother with HSV (neonatal herpes – symptoms appear during the first month of delivery), asymptomatic cases, susceptible partner, symptoms outbreak, patients with suppressed immune system eg. Conditions like HIV/AIDS, recipients with organ transplantation, etc. Serological HSV – 1 (IgM) test helps to detect IgM class antibodies which are detectable for 10 to 21 days from the day during initial exposure of the infection. Later class switching of antibody type occurs, thereby the levels of IgM get diminished, and IgG levels takeover. Hence serological HSV -1 IgG test is performed to detect the presence of HSV infection in the suspected patient’s body. Complications of chronic untreated HSV can disseminate and can develop HSV encephalitis (inflammation caused in the brain due to HSV infection). Additional tests include STD test panel which includes partner(s). Other tests include testing on CSF sample specimen with signs and symptoms, HSV- DNA using molecular assays such as real-time PCR, NAAT – Nucleic Acid Amplification Testing (more sensitive), viral culture, Tzanck smear (sample specimen scraped from the patient’s sore) for microscopic examination, etc.
