Introduction to HSV-1

Herpes Simplex Virus Type 1 (HSV-1) is a common viral infection, primarily causing oral herpes. A significant proportion of the population worldwide is infected with HSV-1, often asymptomatically.

Understanding HSV-1 Serology Testing

HSV-1 testing commonly involves serology tests, which detect antibodies in the blood: Immunoglobulin G (IgG) and Immunoglobulin M (IgM).

HSV-1 IgG vs. IgM

IgG and IgM are both antibodies, but they indicate different stages of infection:

• HSV-1 IgG: Indicates past exposure and usually remains in the body for life. Detected IgG levels suggest a previous or long-standing infection.
• HSV-1 IgM: Suggests a recent infection or reactivation. IgM antibodies typically appear within 1 to 2 weeks after infection and disappear within a few weeks, although they can sometimes be present during reactivation.

Interpreting Test Results

Understanding the results of HSV-1 IgG and IgM tests is crucial for diagnosis and patient management:

• IgG Positive, IgM Negative: Indicates past infection with HSV-1.
• IgG Negative, IgM Positive: Suggests a current or recent acute HSV-1 infection.
• IgG Positive, IgM Positive: Points to a recent infection or reactivation of an existing infection.
• IgG Negative, IgM Negative: Suggests no recent or prior HSV-1 infection.

The specificity and sensitivity of IgG assays are generally high, often over 90%, while IgM tests may exhibit cross-reactivity with other viruses, affecting specificity.
