Purpose: Evaluate second generation Thermo Scientific Exactive™ high performance bench-top mass spectrometer for analysis of immunosuppressant drugs in whole blood for clinical research use only utilizing the Thermo Scientific ClinSpec Immunosuppressant Test kit and samples previously analyzed by a clinically validated method on a triple stage quadrupole mass spectrometer. Methods: Whole blood samples were processed by precipitation with ZnSO4/ methanol. Samples were injected onto an HPLC under gradient conditions and detected on an Exactive Plus mass spectrometer. Results: Standards and controls from test kit passed all method parameters for linearity recovery. This method showed excellent correlation with a clinically validated triple stage quadrupole method.
