Herpes Simplex Virus 1 & 2, IgG & IgM
Understanding Herpes Simplex Virus 1 & 2, IgG & IgM
What is Herpes Simplex Virus 1 & 2, IgG & IgM?
The Herpes Simplex Virus 1 & 2, IgG & IgM test is a blood test done to detect the presence of immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies against herpes simplex virus (HSV) type 1 and type 2. HSV-1 typically causes oral herpes, while HSV-2 primarily causes genital herpes. This test helps determine the stage of the infection, differentiate between recent (acute) and past (chronic) infections, and aid in the appropriate and timely management of the infection.
Herpes simplex virus (HSV) infection (herpes) is a skin infection that may spread through sexual contact or skin-to-skin contact with an infected person. HSV is classified into two types based on the areas they typically affect and how they are spread: HSV-1, which usually causes oral herpes, characterized by cold sores or fever blisters around the mouth, and HSV-2, which primarily causes genital herpes.
The Herpes Simplex Virus 1 & 2, IgG & IgM test measures two types of antibodies: Immunoglobulin G (IgG) and Immunoglobulin M (IgM) produced as an immune response against HSV-1 and HSV-2. IgM antibodies suggest a recent or acute infection, as they are produced early in the immune response and usually decline after a few months. IgG antibodies indicate past or chronic infection with the virus, as they typically develop after the initial infection and persist for life.
The primary purpose of the Herpes Simplex Virus 1 & 2, IgG & IgM test is to diagnose HSV-1 and HSV-2 infections by detecting IgG and IgM antibodies in the blood. It also helps distinguish between recent (acute) and past (chronic) herpes infections.
This test is often performed when an individual exhibits symptoms suggestive of a herpes infection, such as sores or blisters around the mouth or genital area, recurring blisters or ulcers, pain during urination, unusual discharge from the urethra and vagina, fever, body aches, sore throat, etc. It may also be part of routine screenings for sexually transmitted infections (STIs) or pre-pregnancy check-ups, as HSV can be transmitted to the baby during childbirth.
No specific preparation is needed to get the Herpes Simplex Virus 1 & 2, IgG & IgM test done. You can eat and drink normally before the test. Talk to your doctor about your specific test results. Narrate your complete medical history and symptoms to help them correlate your clinical and laboratory findings and formulate your treatment plan.
What is Herpes Simplex Virus 1 & 2, IgG & IgM used for?
The Herpes Simplex Virus 1 & 2, IgG & IgM test is done:
- To confirm the diagnosis of herpes simplex virus (HSV) 1 & 2 infection in individuals with suggestive symptoms.
- To find out if an individual has recently or previously (in the past) been exposed to herpes infection.
- For individuals experiencing symptoms of herpes, such as cold or genital sores, or those who have been exposed to the virus and wish to know their infection status.
- As a screening test during pregnancy to prevent neonatal herpes.
What does Herpes Simplex Virus 1 & 2, IgG & IgM measure?
Contains 2 testsThe Herpes Simplex Virus 1 & 2, IgG & IgM test is a blood test used to measure two types of antibodies: Immunoglobulin G (IgG) and Immunoglobulin M (IgM). IgG antibodies indicate a past infection or long-term presence of the virus, while IgM antibodies suggest a recent or acute infection. By identifying these antibodies, this test helps determine if an individual has been exposed to the virus and distinguishes between new and existing infections.
Getting tested helps in the diagnosis and management of herpes infections. Early and precise identification of HSV infections allows timely medical intervention, reducing symptoms and preventing complications. For pregnant women, detecting an HSV infection is crucial to prevent neonatal herpes, which can be severe for newborns. Additionally, knowing one's HSV status helps in taking preventive measures to avoid transmission to sexual partners and others, thus playing a significant role in public health and personal well-being.
Herpes Simplex Virus 1 & 2, IgM
The Herpes Simplex Virus 1 & 2, IgM test is designed to detect IgM antibodies that are produced as a body's first response to a HSV infection. IgM antibodies may take up to 10 days to develop. Also, these antibodies are usually present in higher concentrations shortly after an infection and eventually decrease after a time period (7-10 days). Therefore, the presence of HSV-1 or HSV-2 IgM antibodies typically suggests a recent infection.
Early detection allows doctors to detect symptoms quickly and provide necessary medical interventions to individuals suffering from HSV infection, leading to better outcomes and improved quality of life.

Herpes Simplex Virus 1 & 2, IgG
The Herpes Simplex Virus 1 & 2, IgG test determines the presence of IgG antibodies against HSV-1 and HSV-2 in response to the Herpes infection. Your body begins to make two relevant types of HSV-1 antibody or HSV-2 antibody around 18 to 21 days after you are exposed to the virus and remains in the body for life. The presence of IgG antibodies generally indicates past exposure and immunity against Herpes infection.

Interpreting Herpes Simplex Virus 1 & 2, IgG & IgM results
Interpretations
If the HSV 1 & 2 IgM test is ruled as positive, then the patient is suffering from an active HSV infection.
If the HSV 1 & 2 IgG test results come back as positive, it means that the patient once suffered from an HSV infection.
