Performance of BioFire Blood Culture Identification 2 Panel (BCID2) for the detection of bloodstream pathogens and their associated resistance markers: a systematic review and meta-analysis of diagnostic test accuracy studies

Table 5 Agreement between culture-based methods and BCID2 on polymicrobial blood culture samples

Study	Concordant results / total polymicrobial samples (%)
Berinson et al. [9]	19/31 (61.3)
Sparks et al. [12]	5/7 (71.4)
Cortazzo et al. [13]	35/35 (100)
Peri et al. [29]	1/2 (50)

Total	75/90 (83)

In the study by Lu et al. [32, 33] 125/1074 positive blood cultures samples had multiple targets detected by BCID2 of which 43/125 (34.4%) had perfect agreement with conventional testing. When omitting the 53 false positive results due to the presence of nucleic acid from non-viable E. coli in specific lots of blood culture bottles, agreement with conventional testing was 43/84 (51.2%)
