From: Clinical on-site monitoring of ß-lactam antibiotics for a personalized antibiotherapy
Calibration curves (n = 4) of (a) piperacillin, (b) cefuroxime and (c) cefazolin in human serum diluted 1:1000 in PBS for stopflow times of 2 min. The calibration points are fitted with a 4-parametric logistic curve, resulting in an inter-assay coefficient of variation of less than 20% and LODs of 2.07 ng ml−1, 4.88 ng ml−1 and 5.71 ng ml−1 for piperacillin, cefuroxime and cefazolin, respectively. I/I0 represents the current peak obtained for the measured sample (I) normalized to the current peak for a sample free of antibiotic (I)
