2.2 Blood sampling and analytical assays
Blood samples were collected in the morning before dosing when
voriconazole reached steady-state. Voriconazole Cminwere analyzed by enzyme immunoassay technique (EMIT)using Siemens VIVA-E
automatic detector (Siemens healthcare Diagnostic Inc, Newark, USA) with
the voriconazole test kit (No.20190401) from Zhuhai Li zhu Reagent Co.,

possessing good precision (coefficient of variation ≤10%) and accuracy
(relative bias within ±15%).
