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.

Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

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.
