Generally, 1.5 to 2 inches of scalp or body hair is required for testing. Hair analysis can detect drugs, alcohol/ETG, and offers customizable testing options.
Recently, hair follicle drug testing has gained popularity for substance checks. Employers, courts, and professionals now opt for this over traditional urine tests. Employers with zero-tolerance policies, judicial systems, and probation officers favor hair tests. The key advantage is its extensive detection period, up to 90 days, making it reliable and tamper-proof. For more recent drug use, within 5 days, urine tests retain higher accuracy.

Hair testing is now regarded as an effective means for detecting drug and alcohol usage. Through capturing biomarkers within the fibrous structure of growing hair, it yields an extended history of alcohol and drug consumption. When taken from near the scalp, hair samples offer close to a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and easy to transport.
A 1.5-inch sample of about 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp will yield 100mg, the optimal sample for screening and verifications. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair is unobtainable, an equivalent body hair sample may be used. When mentioning head hair, it refers solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
There are four inherent steps in laboratory processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial procedure of incorporating a sample into the laboratory system. It involves confirming the sample was sealed and delivered correctly, generating a random LAN (Laboratory Accessioning Number), and performing additional data logging not provided by an electronic custody system.
Screening constitutes a preliminary swift assessment for substances of abuse. While Screening efficiently rules out drug use in most cases, a positive outcome demands confirmation for court viability. Samples with presumptive positives in Screening require secondary verification.
Upon encountering a presumptive positive in Screening, further hair from the original sample is prepared for Extraction. Drugs are isolated at notably lower concentrations in hair than in other sample types (e.g., urine or oral fluid), making hair drug testing exceptionally challenging.
Positive screenings undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo necessary washing before confirmation. The entire process from Accessioning to Confirmation is audited under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.
