The clavicle bone as an alternative matrix in forensic toxicological analysis.

Although human blood is the reference medium in the field of forensic toxicology, alternative matrices may be required when traditional specimens are not available, especially in the investigation of cases involving decomposing remains. Clavicle bone may provide an appropriate sample of choice since it can easily be obtained at autopsy after the removal of the breastplate for the inspection of the thoracic viscera. To the author's knowledge, this is the first time that clavicle bone is used as an alternative matrix for the detection of drugs.
