Test Details
Methodology
Polymerase chain reaction (PCR)
Result Turnaround Time
3 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
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.
