Values are given as (number of BAL specimens with the same bacterial target reported as predominant by PN panel and culture)/(number of BAL specimens with the indicated number of bacterial and PN panel detections).
One specimen was reported as 106 S. aureus and 105 E. cloacae by the PN panel with only 105 E. cloacae reported in culture, and one specimen was reported as 105 S. aureus and 104 E. cloacae by the PN panel with only 104 E. cloacae reported in culture.
One specimen was reported as 107 S. pneumoniae and 105 P. aeruginosa by the PN panel while culture reported 104 P. aeruginosa and “few” S. pneumoniae.
One specimen was reported as 105 S. aureus and 104 K. oxytoca, S. marcescens, and P. aeruginosa by the PN panel while culture reported 104 K. oxytoca, S. marcescens, and P. aeruginosa and only 103 S. aureus.
