Abstract:Determination of Tetramethylenedisul in blood is the gist for deciding whether or not being poisoning. Accuracy of the result has a significant effect on both clinical judgments and decisions of the health administration and supervision department. The uncertainty is an important index reflecting the accuracy of results. So it is necessary to analysis the uncertainty of the measurement of Tetramethylenedisul in blood, When the concentration of blood sample is 30.48μg/L and expanded factor K is equal to 2, Overall Expanded Uncertainty is 3.3μg/L.[著者文摘]
