Unraveling the Past: Insights from the Herpes Simplex Virus-I IgM Test
A herpes IgM test can detect early HSV infection by looking for IgM antibodies. Your body produces IgM and IgG antibodies after HSV infection. The IgM test can detect HSV earlier than the IgG test. A positive IgM test might mean you have a new or recurrent HSV infection.
