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.

Limitations

This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.

Methodology

Polymerase chain reaction (PCR)
