Fig. 4From: Evaluation of the clinical and quantitative performance of a practical HPLC-UV platform for in-hospital routine therapeutic drug monitoring of multiple drugsComparison of Passing–Bablok regression analysis (D1, E1) and Bland–Altman analysis (D2, E2) results of the serum levels of two drugs (LTG, VRCZ), which were separately quantified by the present HPLC-UV platform and by a HPLC-MS/MS system. Quantification by HPLC-UV was performed in our hospital, while that by HPLC-MS/MS was conducted by the outsourced provider (SRL, Inc.)Back to article page
