Abbreviations: PCR-ST polymerase chain reaction with SepsiTest™, BC blood culture, spp. species
aone sample contained CoNS in blood culture and CoNS + Corynebacterium in PCR-ST
bone sample contained Enterococcus faecalis in blood culture and Enterococcus + Streptococcus spp in PCR-ST
cfor microorganisms detected in polymicrobial samples, see Table 3
In total 236 samples were analyzed of which 79 were positive in one or both methods. Results are presented by likelihood of bacteremia, true/probable/possible versus questionable bacteremia
