What is Babesia microti IgM Antibody?

IgM antibodies to B. microti appear early in the course of infection, typically within the first weeks, and decline over months. IgM is less sensitive than IgG for chronic or low-level infection and can be absent in immunocompromised patients or reactivated disease.

Why is Babesia microti IgM Antibody measured?

IgM is a marker of acute or recent infection. Its presence alongside IgG increases the specificity of serological diagnosis in the acute phase, though false-negative IgM is common once the infection becomes subacute or chronic. IgM must be interpreted cautiously because cross-reactivity and prolonged low-level positivity can occur.
