[The Application Study of Voriconazole and Its Metabolites Concentration Monitoring in Allogeneic Hematopoietic Stem Cell Transplantation Patients].

To explore the application value of simultaneous monitoring of voriconazole (VRCZ) and voriconazole N-oxide (VNO) in efficacy and safety of VRCZ in the prevention and treatment of fungal infections in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients before engraftment (i.e., days +1 to +30 after transplantation).
