Cefazolin is a broad-spectrum antibiotic used primarily as a prophylactic care for patients during surgery. In specific groups of patients, we encounter variability in pharmacokinetics from the population average. To optimize dosing regimens, reliable bioanalytical methods capable of rapid sample determination should be used. Currently, the most widely used method for measuring plasma concentrations is liquid chromatography with UV or MS detection. Protein precipitation and solid phase extraction can be used for pre-analytical sample preparation. Equilibrium dialysis or ultrafiltration can be used if the free fraction needs to be determined. Undesirable factors affecting the accuracy of the assay may be matrix effects or low sample stability.
