Popis: Recently, global health concerns regarding increasing multidrug resistance have arisen. This study aimed to develop a simple, inexpensive and rapid high-performance liquid chromatography-ultraviolet (HPLC-UV) method for determining urinary concentrations of a first-generation cephem antibiotic in pediatric patients with urinary tract infections (UTIs). HPLC-UV was used to analyze urinary cefazolin concentrations at a detection wavelength of 254 nm. The assay used contained 10-fold diluted urine with an internal standard (cephapirin). The standard calibration curve for cefazolin was linear in the concentration range of 31.25-500 μg/ml (r
