Coxiella burnetii (Q fever) PCR, S

Useful For

Aiding in the diagnosis of Coxiella burnetii infection (ie, Q fever) using serum specimens

Serum


Specimen Required


The high sensitivity of amplification by polymerase chain reaction requires the specimen to be processed in an environment in which contamination of the specimen by Coxiella burnetii DNA is unlikely.

Interpretation

A positive result indicates the presence of Coxiella burnetii DNA.

 

A negative result indicates the absence of detectable C burnetii DNA but does not negate the presence of the organism and may occur due to inhibition of PCR, sequence variability underlying primers or probes, or the presence of C burnetii DNA in quantities less than the limit of detection of the assay.
