Comparison of FilmArray respiratory panel using paired nasopharyngeal swab and BAL samples collected from immunocompetent hosts ().

Number (%) of NP swab samples with a FilmArray result	Number (%) of BAL specimens with a FilmArray result
	Positive	Negative
Positive	1 (4.0)^a	0 (0.0)
Negative	1 (4.0)^b	23 (92.0)
