Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a comprehensive record of drug and alcohol intake by embedding biomarkers within the fibers as the strand grows. When taken from near the scalp, hair is capable of offering nearly a 90-day window to detect alcohol and drugs. This method is straightforward to collect, relatively tamper-resistant, and simple to transport.
A sample measuring 1.5 inches, with about 200 hair strands (equivalent to a #2 pencil's thickness) nearest to the scalp, yields 100mg of hair, which is an optimal amount for analysis and confirmation. For tests involving EtG, additional components, or exceeding 10 panels, a 150mg specimen is advisable. It's suggested to measure the specimen with a jeweler's scale. If scalp hair isn't available, a comparable volume of body hair may be used. Regarding head hair, this specifically pertains to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The lab processing of a drug test follows four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory phase where the sample is inducted into a lab's system. This step confirms the sample's proper sealing and shipping, allocates a random LAN (Laboratory Accessioning Number), and finalizes any added data entry not supplied by an electronic chain of custody system.
Screening represents an initial rapid review for drug presence. Even though Screening provides an affordable way to exclude drugs in most samples, a court-viable result requires confirmation of a positive screen. Any samples that appear positive during Screening must undergo further confirmation.
For samples showing a presumptive positive in Screening, additional hair is sourced from the original specimen for Extraction. During this phase, drugs are drawn out from hair at considerably lower concentrations than other techniques (such as urine or oral fluid), making hair drug screening the most challenging technique to execute.
The final stage, Confirmation, is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo cleaning prior to confirmation when necessary. The comprehensive lab process, from Accessioning through Confirmation, is scrutinized under CAP (College of American Pathologists) Hair standards and adherence to ISO / IEC 17025 accreditation.

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.
