Order Code KKBRP Kingella kingae, Molecular Detection, PCR, Blood

Useful For

Aiding in the diagnosis of Kingella kingae infection using whole blood specimens

Method Name

Real-Time Polymerase Chain Reaction (PCR)

Reporting Name

Kingella kingae PCR, B

Specimen Type

Whole Blood EDTA


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 Kingella kingae DNA is unlikely.

Specimen Minimum Volume

0.5 mL

Specimen Stability Information

Specimen Type Temperature Time Special Container
Whole Blood EDTA Refrigerated (preferred) 7 days

Method Description

Nucleic acid is extracted from the specimen using the automated MagNA Pure instrument. Target specific primers are used to amplify the rxtB gene region of Kingella kingae; amplification is monitored by detecting fluorescence produced by target specific fluorescence resonance energy transfer hybridization probes. This real-time polymerase chain reaction (PCR) takes place on a LightCycler instrument. Detection of the K kingae target is performed through melting curve analysis using the LightCycler software.(Cockerill FR, Uhl JR: Applications and challenges of real-time PCR for the clinical microbiology laboratory.
