Ordering Guidance


During the acute phase of an Anaplasma phagocytophilum, Ehrlichia chaffeensis, or Babesia infection, serologic tests are often nonreactive and detection by molecular assays is recommended. Polymerase chain reaction (PCR) testing is available to aid in the diagnosis of these cases; see EPCRB / Ehrlichia/Anaplasma, Molecular Detection, PCR, Blood and BABPB / Babesia species, Molecular Detection, PCR, Blood.
