From the beginning of our experience with blood alcohol determinations for evidence in legal cases we have been called upon for information concerning the change of alcohol content in blood specimens after they have been drawn. Samples usually come to this laboratory in chemically clean glass vials stoppered with new corks and containing sufficient dry potassium oxalate to prevent clotting. These containers are obtained ready for use from this laboratory by county officials. However, many blood samples received have been contained otherwise, and often the temperature treatment of the specimens has not been uniform. To have available information about the probability that samples at the time of analysis contained the same amount of alcohol as at the time of drawing we performed suitable determinations, the results of which are presented here.
