Ehrlichia chaffeensis DNA, Real‑Time PCR
Also known as: Tick borne, E chaffeensis, Ehrlichiosis
Use
This molecular diagnostic test by Quest Diagnostics is indicated for detection of Ehrlichia chaffeensis DNA in patients with suspected tick‑borne infection such as ehrlichiosis. As a qualitative Real‑Time PCR assay, it aids in early and accurate diagnosis of active infection when pathogen DNA is detectable in whole blood, supporting timely treatment and clinical management.
Special Instructions
Not provided.
Limitations
PCR for Ehrlichia chaffeensis is most sensitive in early (first week) of illness and sensitivity decreases substantially within 48 hours after antibiotic administration. A negative result does not rule out ehrlichiosis and clinical judgment should guide treatment decisions. Performance characteristics are not specified here.
