Objective To evaluate the measurement uncertainty for the determination of ethanol in human blood by auto-headspace GC/MS.Methods Each source of uncertainty,arising from the procedure of testing,was analyzed and confirmed according to the guidelines of the uncertainty in measurement.After each uncertainty component was evaluated,the combined standard uncertainty and the expanded uncertainty of the result were calculated.Results The expanded uncertainty was 0.084mg/mL when the concentration of ethanol in blood sample was 0.738 mg/mL.Conclusion The measurement uncertainty of the concentration of ethanol was came primarily from the sample determination,standard solution of the ethanol and the calibration curve.
