This study found that analyzing hair samples in young children for drug exposure can indicate environmental drug exposure or in-utero exposure, but cannot definitively confirm deliberate drug administration.

This review discusses the increasing importance of hair analysis in forensic toxicology and highlights the complexities in interpreting results due to external contamination and regional collection differences, but reports no new findings.

This study found that standard decontamination procedures may not fully remove external contamination in post mortem hair specimens, complicating the interpretation of drug detection in such samples.

This review highlights the importance of standardizing pre-analytical procedures for collecting and extracting samples from uncommon biological specimens like breast milk and sweat in clinical metabolomics, to enhance diagnostic and biomarker discovery efforts while minimizing contamination and bias.

This study reports that human eccrine sweat gland cells are capable of forming a stratified epidermis, suggesting they may serve as an additional source of keratinocytes for skin repair.
