Acceptable test for acute or convalescent phase of infection from Anaplasma phagocytophilium. May be useful when PCR testing is not an option (eg, outside the 2 week window for acute phase). However, PCR testing is generally preferred; refer to Tick-Borne Disease Panel by PCR, Blood (2008670) or Ehrlichia and Anaplasma Species by PCR (2007862).
