Hair analysis is gaining recognition as an effective method for identifying substance use, including drugs and alcohol. Hair captures a long-term record of these substances by embedding biomarkers within the strands of growing hair. When samples are taken close to the scalp, they can offer a detection period of up to roughly 90 days for alcohol and narcotics. The process of collecting hair is straightforward, challenging to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (about the size of a standard #2 pencil), will yield 100mg of hair, which is the optimal quantity for both initial screening and subsequent confirmation. For tests inclusive of EtG, additional evaluations, or exceeding 10 panels, 150mg of the specimen is advisable. Utilizing a jeweler's scale for the specimen's weight assessment is recommended. In instances where scalp hair cannot be obtained, an equivalent volume of body hair is an alternative. The term "head hair" specifically pertains to scalp hair, whereas "body hair" encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory analysis of drug testing entails four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample within a laboratory's system. This step involves ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from the electronic chain of custody system.
Screening constitutes an initial rapid assessment for substance abuse. While this step is a cost-efficient means to exclude drug usage in the majority of samples, a positive result needs confirmation for courtroom admissibility. Any samples yielding presumptive positive results in Screening necessitate further confirmation.
Should a sample show a presumptive positive in the Screening phase, more hair will be extracted from the original specimen for the Extraction process. Here, drugs are isolated from hair at much lower concentration levels than other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug testing.
Confirming any positive screening outcomes is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives undergo a wash before confirmation as required. The entirety of the laboratory sequence from Accessioning to Confirmation is conducted in compliance with both the CAP (College of American Pathologists) designation for Hair and ISO / IEC 17025 accreditation standards.

Note: Although often termed "hair follicle tests," the evaluation focuses on the hair strand and not the scalp's hair follicle.

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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
