Role of the toxicology laboratory in the treatment of acute poisoning.

The modern toxicology laboratory can play an important role in the evaluation of poisoning. In order to appreciate the nature and extent of this role, several essential elements necessary to an acute care toxicology service should be considered. When an ongoing and effective dialogue between clinicians and the toxicology laboratory staff is established, and a broadly based analytical approach is applied to the analysis of the appropriate biological fluids, a dynamic and viable toxicology service will result. How these elements work together to facilitate this service will be discussed, based primarily on experience in a large teaching hospital. This experience indicates that if the elements necessary to provide laboratory support in the investigation of an alleged poisoning are in place, the toxicology laboratory plays an important role in ensuring optimum and effective patient care.
