Klebsiella quasipneumoniae is a Gram-negative, facultatively anaerobic, encapsulated rod in the family Enterobacteriaceae, closely related to Klebsiella pneumoniae and separated from it through genomic analyses. It comprises two subspecies (subsp. quasipneumoniae and subsp. similipneumoniae) and is isolated from clinical specimens including blood, urine, and respiratory samples. K. quasipneumoniae can harbour extended-spectrum beta-lactamase and carbapenemase genes, though it is generally less frequently associated with multidrug resistance and hypervirulence than K. pneumoniae.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
