Current state of drug analysis in Japanese emergency departments: a nationwide survey.

In the treatment of acute poisoning, drug analysis is important for both clinical judgment and academic verification. However, many of the 15 toxicants proposed to be useful for analysis in 1999 are not yet immediately analyzed in the emergency department of Japanese hospitals. Furthermore, it is necessary to develop inexpensive testing systems and to provide insurance points for testing so that analysis can be carried out by emergency departments.
