Ehrlichia sp., DNA PCR
Also known as: Human Monocytic Ehrlichia (HME) by PCR
Use
This test is intended to be used as an aid in the diagnosis of human monocytic ehrlichiosis (HME) caused by Ehrlichia chaffeensis. This assay will also detect other Ehrlichia species including E. ewingii and E. muris.
Special Instructions
The assay will not differentiate among the Ehrlichia species it detects. Results should be interpreted in conjunction with other clinical and laboratory findings.
Limitations
This test was developed and its performance characteristics determined by Labcorp, and it has not been cleared or approved by the Food and Drug Administration. Potential limitations include interference by inhibitors present in the sample that may affect the accuracy, potential for cross-reactivity with other bacterial DNA, and inability to determine specific load or severity of infection.
