Hair analysis has emerged as an effective method for identifying consumption of drugs and alcohol, as it holds a long-term record by embedding biomarkers within the hair’s fibers as it grows. When taken near the root, hair enables an approximate 3-month time frame for detecting alcohol and substance use. Collecting hair is straightforward, challenging to tamper with, and is easily transported.
A 1.5-inch segment consisting of around 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for analysis and confirmation. For EtG, supplemental, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. In instances where scalp hair is inaccessible, an equivalent amount of body hair may be gathered. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The core stages in laboratory processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the preliminary integration of a specimen into a lab's system, involving assurance that the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent from an electronic chain of custody system.
Screening comprises a preliminary inspection for substance abuse. While Screening is an economical approach to eliminate drug usage in most cases, a positive screen necessitates affirmation to be legally admissible. All samples presumptively positive in Screening require further confirmation.
Upon encountering a presumptive positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at substantially lower concentrations than other methods (ex. urine or oral fluid), making hair analysis the most intricate method to execute.
Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and following ISO / IEC 17025 standards.

Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
