A review of present measuring devices and procedures, based on information obtained from the literature, has led to the following conclusions: The selection of method of determining the b.a.c. for research purposes amounts to a choice between blood and breath analysis. Further research is required before this choice can be made. The SWOV has contributed to this by means of laboratory experiments in order to assess the calibration and accuracy of several instruments. In addition, preliminary technological investigations have been made preparatory to more extensive research into the value of blood and breath analysis under practical conditions. This more extensive research has, however, been delayed by unforeseen circumstances outside the scientific sphere.
