Resumen

La determinación de drogas de abuso en pelo es hoy en día una técnica habitual implan tada en los laboratorios de toxicología forense que siguen las recomendaciones propues tas por la Society of Hair Testing en el año 2004. Es una muestra biológica alternativa de fácil recogida, difícil adulteración, que no necesita condiciones especiales de conserva ción y, además, permite demostrar consumos anteriores a la toma de muestra. Es por ello que sus aplicaciones son cada día numerosas, incluida la posibilidad de determinación de marcadores de consumo crónico de alcohol etílico. No obstante, los métodos analíticos no están aún estandarizados por lo que ha de realizarse una correcta interpretación de resultados y tener en cuenta las limitaciones que esta muestra biológica presenta.

Abstract

The determination of drugs of abuse in hair is now a routine technique in forensic toxicology laboratories following the Society of Hair Testing recommendations in 2004. It is an alternative biological sample that is, easily obtained, difficult to adulterate, does not require special storage conditions, and, furthermore, it demonstrates shows consumption prior to obtaining a blood or urine sample. For this reason, its applications are increasing in number, including the possibility of determining markers of chronic ethyl alcohol use. However, the analytical methods are not yet standardized; therefore, a correct interpretation of results must be performed, and the limitations of this biological sample must be taken into account.
