Herpes Simplex Virus 1, IgM

Herpes simplex virus (HSV), also known as herpes, is responsible for causing infections related to the skin. HSV-1 is one of the strains of HSV which is primarily associated with oral herpes, causing cold sores or blisters around the mouth and lips. It can spread through skin-to-skin contact such as kissing. However, it can also cause genital infections. The infection lasts a lifetime. Most HSV infections are asymptomatic (without symptoms) or unrecognized, but symptoms of herpes include painful blisters or ulcers that can recur over time. Herpes is not curable, however, it can be well managed with medications. 

The Herpes Simplex Virus 1, IgM test looks for IgM antibodies that are specific to HSV-1. This means that the IgM antibodies can bind to and interact with HSV-1, indicating that the body has been recently exposed to the HSV-1 infection. Therefore, the presence of HSV-1 IgM antibodies typically signifies an active or recent infection, as these antibodies are produced shortly after the onset of symptoms and decline over time. HSV-1 IgM antibodies may also be found in individuals who have reactivation of a previous herpes infection.

Your doctor may recommend the Herpes Simplex Virus 1, IgM test when you are experiencing symptoms suggestive of oral herpes infection such as blisters that appear either individually or in clusters; they can be quite painful and may ooze; soreness, pain, and burning at the injection site; headaches; fever; body aches and pains. Also, the Herpes Simplex Virus 1, IgM test is used to confirm the presence of the virus during the early stages of infection or for individuals experiencing their first outbreak.

No special preparation is needed before undergoing the Herpes Simplex Virus 1, IgM test. Talk to your doctor about your specific test results and narrate your complete medical history and symptoms to help them correlate your clinical and laboratory findings.
