The HSV 1-IgM test is a blood test used to detect IgM antibodies against Herpes Simplex Virus type 1 (HSV-1). The presence of IgM antibodies usually indicates a recent or active infection, as IgM antibodies are typically the first type of antibodies produced by the body in response to an infection.

Test Description:

Purpose of the Test:

• The HSV 1-IgM test helps to detect an early or current HSV-1 infection.
• It is useful when someone presents with new or recurring symptoms of herpes, such as sores or blisters around the mouth or other areas of the body.

What the Test Detects:

• The test specifically looks for IgM antibodies to HSV-1, which appear shortly after initial exposure to the virus.
• IgM antibodies are usually present in the early stages of infection and tend to decline after the acute phase.

When the Test is Ordered:

• If there are symptoms of an active infection, such as cold sores or lesions.
• To determine if an acute outbreak is due to HSV-1.
• During an outbreak to distinguish between a new infection or reactivation of a latent virus.

Sample Collection:

• The test requires a blood sample, typically drawn from a vein in your arm.

Test Procedure:

• A healthcare professional will clean the puncture site and use a needle to collect blood.
• The blood sample is sent to a laboratory for analysis.
