Interpretive Data

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.

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.

Compliance Category

Laboratory Developed Test (LDT)

Note

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.
