ABSTRACT:
Methods that permit the rapid release of one or more analytes from head or body hair or other keratinized structures of an individual (who may previously have ingested one or more of the analytes) are provided. The methods can include contacting the keratinized structure with a reducing agent but not with a proteolytic agent. The methods can further include identification and quantification of the one or more analytes by known analytical techniques such as immunoassays. The described methods do not damage the analyte and do not cause harmful effects on a subsequently-used analyte detection probe (e.g., an antibody).
