As a potential alternative to whole-blood tacrolimus (TAC) monitoring, a sensitive and selective method was developed for quantifying this immunosuppressant in human peripheral blood mononuclear cell population (PBMCs). These cells, expected to be a more specific biological matrix than whole blood to reflect pharmacological efficacy, could be promising for TAC therapeutic drug monitoring (TDM). The assay was developed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). PBMCs are isolated from 7 mL whole blood by centrifugation over Ficoll gradient density and washed twice with …
