Recently, drug testing has increasingly involved hair follicle exams. Employers, courts, and Substance Abuse professionals prefer hair testing over traditional urine tests. Hair tests are ideal for employers with zero-tolerance drug policies, courts, and people on probation. Their chief advantage lies in detecting drug use over a longer duration—up to 90 days—with a supervised collection that's hard to alter. However, for detection within five days, urine tests remain the most precise tool.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair evaluations are now recognized as a robust method for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of alcohol and various drug use by embedding biomarkers within the fibers of the growing hair filament. When sourced near the scalp, hair can offer up to around a three-month observation period for alcohol and drug usage. Hair is easy to obtain, relatively resistant to tampering, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample weight for analysis and verification. For EtG, additional tests, and/or assessments beyond 10 panels, a quantity of 150mg is advised. We suggest measuring the sample on a jeweler's scale. Where scalp hair is not accessible, a comparable quantity of body hair may be used. By head hair, we mean exclusively scalp hair. Body hair refers broadly to other types such as facial and underarm hair, and so forth.
Process Overview
The primary four stages in laboratory processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning centers on the initial processing of a sample n a laboratory's framework, encompassing verification of properly sealed and dispatched samples, allocation of a random LAN (Laboratory Accessioning Number), and finalization of any additional data recording absent from an electronic chain of custody system.
Screening constitutes an initial swift test for drug misuse. While Screening affords a cost-effective method to negate drug use in the majority of samples, positive screening results necessitate confirmation for court acceptance. All samples that show presumptive positivity in Screening mandate a further confirmatory test.
Upon a presumptive positive in the Screening stage, additional hair is extracted from the primary sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to administer.
Should a positive result arise in screening, Confirmation is executed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed before final verification if necessary. The complete lab routine from Accessioning through to Confirmation is evaluated under both CAP (College of American Pathologists) Hair certification and accreditation under ISO / IEC 17025 benchmarks.

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.
