Abbreviations: PCR-ST polymerase chain reaction with SepsiTest™, BC blood culture, spp. species
^aTwo additional polymicrobial PCR-ST results are listed in Table 2: these samples contained two microorganisms in the PCR-ST and one concordant microorganism in the corresponding BC
A polymicrobial sample, a sample that yielded more than one microorganism, was considered as true, probable or possible bacteremia, when one of the detected microorganisms met the definitions for true, probable or possible, regardless of the meaning of the other microorganisms
