NettetOne of the first alternative calibration strategies in clinical LC-MS used a single-point (linear through zero) calibration for quantifying the immunosuppressant tacrolimus (7). A subsequent study by the same group expanded the repertoire of abbreviated calibration curves and evaluated the performance of these curves in quantifying sirolimus (8).
