Streszczenie
The theoretical influence of the amount of blood in a sample vial on the variation of ethanol concentration in such a sample has been analysed in this paper. It was ascertained that changes in ethanol concentration for “typical” vial contents are so small that they can be seen as negligible, as the variation is only evident at positions far behind the decimal point. Variations greater than 0.06‰ occur only in vials that are filled to less than 5% of their capacity. On the basis of this, a conclusion has been formulated that vial content level does not have any practical influence on ethanol measurements if the content is greater than 5% of the vial’s total volume. The conclusion refers only and exclusively to cases where the vial is sealed.
