Interpretation
A positive IgM result indicates a recent infection with varicella-zoster virus (VZV).
A negative result does not rule out the diagnosis of VZV infection. The specimen may have been drawn before the appearance of detectable antibodies. Negative results in suspected early VZV infection should be followed by testing a new specimen in 2 to 3 weeks.
