These hair tests can identify drugs, alcohol/ETG, and other specialized test options.
Over the past few years, hair follicle drug testing has become more prevalent in drug testing procedures. Numerous employers, judicial systems, and Substance Abuse professionals prefer hair drug tests over the conventional urine analysis. These tests are adopted by zero-tolerance employers, courts, and probationary individuals. The primary advantage of a hair follicle drug test is its extended detection period—often up to 90 days—with collection under supervision, ensuring authenticity and difficulty in tampering. Nevertheless, for detecting drug usage in the past five days, the urine test remains the most precise method.

Hair analysis has evolved into a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances like alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When gathered near the scalp, it can offer a detection period of up to three months for alcohol and drugs. Hair sample collection is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch section containing about 200 hair strands (roughly the width of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation purposes. Additional tests, such as EtG or those exceeding 10 panels, require 150mg of the sample. It's advisable to measure the sample using a jeweler's scale. Should scalp hair be unavailable, a similar quantity of body hair may be utilized. When discussing head hair, we specifically mean scalp hair. Body hair includes every other type such as facial and axillary.
Process Overview
The procedure for laboratory analysis of a drug test consists of four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary involvement of incorporating a sample into the laboratory's system. This step ensures the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data entry that wasn't included by an electronic chain of custody.
Screening provides an initial cursory assessment for potential drug abuse. It's an economical approach to exclude drug use on many samples; however, a positive screen requires confirmation to be acceptable in court. Any samples appearing positive from Screening necessitate a subsequent confirmation.
Should a sample appear positive at the Screening phase, additional hair is retrieved from the initial sample to prepare for Extraction. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug testing is a more intricate methodology.
Confirmation of any positive findings from screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All tentative positive samples undergo a cleansing process before confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is meticulously examined under both the CAP (College of American Pathologists) Hair certification and meets ISO/IEC 17025 standards.

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.
