Cautions

Previous episodes of human granulocytic ehrlichiosis (anaplasmosis) may produce a positive serologic result.

 

In rare instances, clinical evidence of infection may also be derived by direct microscopic examination of Giemsa- or Diff-Quik-stained peripheral blood buffy coat smears, which may reveal clusters of round, dark-purple stained, small dots (morulae) in the cytoplasm of polymorphonuclear cells. However, this is a very insensitive method.

 

Performance characteristics have not been established for hemolyzed or lipemic specimens.
