This study describes the performance of the different methods used for blood alcohol analysis by the Belgian laboratories participating in the external quality assessment scheme. The best performance was achieved by the gas chromatography (GC) and the enzymatic methods. The enzymatic methods are easier to use but more apparatus-dependent, whereas GC methods display higher precision, especially at concentrations near the critical legal limit of 0.5 g/l.
