Value of hair analysis in postmortem toxicology

摘要: It is generally accepted that chemical testing of biological fluids the most objective means diagnosis drug use. The presence a analyte in specimen can be used to document exposure. standard postmortem general unknown screening, followed by gas chromatographic/mass spectrometric confirmation conducted on whole blood sample. In recent years, remarkable advances sensitive analytical techniques have enabled analysis drugs unconventional specimens such as hair. advantages this sample over traditional media, like urine and blood, are obvious: collection almost non-invasive, relatively easy perform, forensic situations it may achieved under close supervision law enforcement officers prevent adulteration or substitution. Moreover, window detection dramatically extended weeks, months even years. aim review current status hair toxicology.
