Clinical Significance
Human granulocytic ehrlichiosis (HGE) DNA PCR is a highly sensitive and specific method to detect the agent responsible for HGE, Ehrlichia equi and Ehrlichia phagocytophilia. This assay does not recognize sequences for the human ehrlichial pathogen Ehrlichia chaffeensis. The diagnosis of HGE infection should be considered in conjunction with clinical presentation and additional established clinical tests. A negative PCR result indicates the absence of HGE at detectable levels in the sample tested and does not exclude the diagnosis of disease.
