Supportive Data
This assay was validated by testing 30-spiked positive ETDA whole blood samples and 10-negative samples. No PCR inhibitors were encountered. The assay was 100% sensitive and specific. The assay showed no cross-reactivity when tested with a panel of 67 bacterial isolates, including Kingella species other than kingae. The limit of detection in EDTA-whole blood was 1.3 CFU/mcL.
