Laboratory Diagnosis
Three tests can be performed to determine an A. phagocytophilum infection:
- Indirect immunofluorescence assay is the principal test used to detect infection. The acute and convalescent phase serum samples can be evaluated to look for a four-fold change in antibody titer to A. phagocytophilum.
- Intracellular Inclusions (morulae) are visualized in granulocytes on Wright- or Giemsa- stained blood smears.
- Polymerase chain reaction assays are used to detect A. phagocytophilum DNA.

Famous quotes containing the word laboratory:
“The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.”
—Nancy Hale (b. 1908)
