Carbapenems are typically reserved for serious infections caused by multidrug-resistant bacteria. blaKPC-producing organisms — first identified in Klebsiella pneumoniae but now found in many Enterobacterales — can break down carbapenems, leaving very limited treatment options.
bla KPC detection is a critical part of molecular testing for serious gram-negative infections, particularly bloodstream, urinary tract, and hospital-acquired infections. Rapid identification allows clinicians to use last-resort antibiotics such as ceftazidime-avibactam, meropenem-vaborbactam, or imipenem-relebactam, and to implement appropriate infection control. Sample type is typically a culture isolate or direct specimen.
