Special Info

Serum, plasma and heparinized specimens are unacceptable. This test is New York DOH approved.

Clinical Info

This is the preferred panel for diagnosing possible tick-borne disease (i.e., Anaplasmosis or Ehrlichiosis) during the acute phase of the disease. A negative result does not rule out the presence of PCR inhibitors in the patient specimen or test-specific nucleic acid in concentrations below the level of detection by this test.

Clinical Limitation

This test detects and speciates Anaplasma phagocytophilum; Ehrlichia chaffeensis; E. ewingii/E. canis; E. muris-like. The nucleic acid detected from E. ewingii and E. canis cannot be differentiated by this test. A result of 'Detected' for E. ewingii/canis indicates the presence of either of these two organisms in the specimen.
