Test Details


Use

This test is intended to be used as an aid in the diagnosis of both human granulocytic anaplasmosis (HGA), formerly known as human granulocytic ehrlichiosis (HGE), caused by Anaplasma phagocytophilum and human monocytic ehrlichiosis (HME). The HME assay will detect but not differentiate multiple Ehrlichia species including E. chaffeensis, E. ewingii and E. muris.

This assay will also detect other Ehrlichia species including E. ewingii and E. muris.
