[Forensic value of analytic results from less than 5 (4) blood alcohol values of a blood sample]

1. If the material for blood-alcohol examinations is insufficient under the existing regulations (specification in the GUTACHTEN DES BUNDESGESUNDHEITSAMTES) it is possible to determine the mean value almost certainly, estimating the confidence-interval. This mean value can be taken as basis of the opinion with regard to safe driving. 2. The proposed statistical procedure is described and compared with other suggested calculations. 3. Testing the proposed procedure by means of 1,426 real data, the usefulness of the proposed calculation is shown.
