March 2006 in “Journal of Chromatography B” The review from 2006 discussed the potential of using hair analysis to monitor veterinary drug misuse in livestock. It highlighted the advantages of hair as a matrix for drug detection, such as its non-invasive collection and the ability to retain drug residues longer than other biological samples like urine or blood. However, the review noted that studies on veterinary hair analysis were limited and faced challenges, including the need for reliable analytical methods to detect low concentrations of drugs and the influence of various factors on drug accumulation in hair. Despite these challenges, hair analysis was considered promising for detecting anabolic agents and other drugs in livestock, offering a retrospective detection advantage.
