title: Performance characteristics and clinical predictive value of the string test for detection of hepato-virulent Klebsiella pneumoniae isolated from blood cultures.
abstract: This study evaluated the phenotypic string test for identifying Klebsiella pneumoniae bacteraemic isolates associated with primary liver abscess. Test reproducibility and repeatability exceeded 95%, with varying sensitivity (66-90%) and specificity (64-67%) depending on cut-off values. The positive predictive value of a positive string test for identifying hepato-virulent isolates was <35%.
