Lately, drug testing techniques have increasingly favored hair follicle assessments. Many organizations, judicial systems, and substance abuse experts are opting for hair drug tests over traditional urine evaluations. Employers with zero-tolerance policies, courts, and those on probation prefer these tests due to their extended detection window, usually up to 90 days, with results collected under observation, making it nearly impossible to tamper with. However, urine tests remain the most precise when detecting recent drug use within the past five days.

Hair examination has become recognized as an effective method for identifying substance and alcohol consumption. Hair offers a prolonged record of alcohol and other substances by capturing biomarkers within the fibers of the expanding hair strand. When sourced near the scalp, hair can reveal up to around a 3-month period for alcohol and other drug detection. Hair collection is straightforward, challenging to tamper, and convenient to transport.
A 1.5-inch section consisting of about 200 hairs (approximately comparable to a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for both screening and verification. For EtG, supplementary analyses, and/or tests exceeding 10 panels, 150mg of the hair is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair may be obtained. Reference to head hair indicates scalp hair exclusively. Body hair pertains to all other hair categories (facial, axillary, etc.).
Process Overview
The four primary steps in the laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a laboratory’s framework. This incorporates confirming that the sample was properly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any further data input not provided by an electronic chain of custody solution.
Screening entails an initial rapid assessment for substance misuse. Although Screening offers an economical approach to exclude substance consumption in most samples, a positive result must be affirmed to be acceptable in court. Samples that show preliminary positivity during Screening necessitate secondary validation.
If a sample is tentatively positive during the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, substances are extracted from hair at significantly reduced concentrations than in different techniques (e.g., urine or oral fluid), which is why hair substance screening remains the most complex practice to undertake.
Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive results are washed prior to confirmation as appropriate. The entire laboratory procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

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.
