Useful For
Aiding in the diagnosis of Kingella kingae infection using tissue or synovial fluid specimens
Method Name
Real-Time Polymerase Chain Reaction (PCR)
Reporting Name
Kingella kingae PCRSpecimen Type
VariesNecessary Information
Specimen source is required.
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.
