Abstract

In analogy to the determination of a lower limiting value of the elimination constant (beta), the quotient Q = 1.80 is recommended for the conversion of a measured urine alcohol concentration into the corresponding blood alcohol concentration at the withdrawal time; only then can a disasvantage to the accused be eliminated with a 99% certainty as based on the statistical interpretation of the results of 328 urine and blood alcohol concentration measurements. The conversion should also be limited to urine alcohol concentrations greater than 1,60(per mille) and to urine samples of non-diabetic persons. Analogous investigations showed that, depending on the storage temperature already at the end of 24 hours, formation of alcohol takes place by which maximal alcohol concentrations as high as 29(per mille) within 7 days may occur. In relation to the time dependence of the alcohol concentration, three different characteristic curves are distinguishable.
