This test is intended to be used as an aid in the diagnosis of Babesia microti infection.

This test is intended to detect Babesia microti, the primary etiologic agent of human babesiosis in the United States. Cross-reactivity may occur with other human pathogenic species, such as Babesia duncani (WA-1), Babesia divergens, and Babesia MO-1. Alternate approaches, such as organism-specific serologic testing, should be considered if a definitive identification is required.
