Diagnostic accuracy of oropharyngeal testing for Kingella kingae in children with bone infections, suggesting limited utility.
Oropharyngeal Kingella kingae DNA was identified in 16 of 16 children with proven K. kingae bone and joint infection (BJI) (sensitivity 100%; 95% confidence interval: 79-100) and in 33 of 112 with disproven K. kingae BJI (specificity 71%; 95% confidence interval: 61-79). Due to low specificity, we advocate against oropharyngeal K. kingae DNA testing as a diagnostic tool in children suspected of BJI.
