Detection of the BNI-1 armored RNA transcript with the ORF 1b assay in different sample matrices^a

Sample matrix	No. detected/no. testedb	Mean CT	Range	SD
Nasopharyngeal secretions	8/8	31.9	31.2-32.8	0.55
BAL fluid	8/8	33	29.6-37	2.37
Plasma	8/8	31.7	30.5-32.8	0.9
Stool	8/8	35.2	32.4-37.5	1.69
Water	7/8	34.4	31.6-37.7	2.14

^aThe BNI-1 armored RNA transcript was added to samples prior to RNA extraction to achieve a 1-μl equivalent of the original armored RNA solution per RT-PCR.
