LOINC description : Ehrlichiosis is a general name to describe several bacterial diseases affecting humans
and animals that are transmitted by tick bites. In the United States, the term ehrlichiosis
may be broadly applied to several different infections. Ehrlichia chaffeensis and
Ehrlichia ewingii are transmitted by the lonestar tick in the southeastern and southcentral
United States. In addition, a third Ehrlichia species provisionally called Ehrlichia
muris-like (EML) has been identified in a small number of patients residing in or
traveling to Minnesota and Wisconsin; a tick vector for the EML organism has not yet
been established. The symptoms caused by infection with these Ehrlichia species usually
develop 1-2 weeks after being bitten by an infected tick. The tick bite is usually
painless, and about half of the people who develop ehrlichiosis may not even remember
being bitten by a tick. [CDC: Ehrlichiosis] This panel contains IgG antibody tests
for two infecting species, E. charffeensis and A. phagocytophilum.;
