Recently, drug testing has frequently utilized hair follicle tests. Employers, judicial systems, and substance abuse experts often prefer hair analysis over urine testing. This test is ideal for employers enforcing strict no-drug policies, courts, or probationers. A significant advantage of hair follicle testing is its extended detection period of up to 90 days, conducted under observation and hard to tamper with. However, to detect usage within the past five days, urine tests remain the most accurate.

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 analysis is recognized as an effective method for identifying drug and alcohol consumption, offering a comprehensive history by capturing biomarkers within the hair's growing strands. When collected near the scalp, it can offer a roughly 3-month detection period for alcohol and other substances. Hair collection is straightforward, resistant to tampering, and convenient for transport.
For optimal screening and affirmation, a hair sample of 1.5 inches, consisting of about 200 strands (comparable to a #2 pencil), yields 100mg, which is ideal. For EtG and additional tests beyond 10 panels, 150mg is suggested. We advocate for specimens to be weighed using a jeweler's scale. If scalp hair isn’t available, a similar quantity of body hair may be used. When referencing head hair, we only mean scalp hair, while body hair encompasses all other types like facial or axillary hair.
Process Overview
Four principal phases form the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is integrated into a lab’s system, involving verification of proper sealing and shipping, assignment of a unique LAN (Laboratory Accessioning Number), and completion of any additional data input not covered by an electronic chain-of-custody system.
Screening is a preliminary evaluation for drug traces. It’s cost-efficient for ruling out drug use in most samples, but positives must be verified for legal validity. Samples with presumptive positives in Screening necessitate secondary confirmation.
In cases of presumptive positivity in Screening, more hair is extracted from the source sample for Extraction, where drugs are isolated at significantly lower concentrations than in other methods like urine or oral fluid, underscoring the complexity of hair drug screening.
Confirmation of positive screen results is performed via GC/MS, GC/MS/MS, or LC/MS/MS, with all presumptive positive samples undergoing cleansing as required. The entire lab process, from Accessioning to Confirmation, aligns with both CAP (College of American Pathologists) Hair designation and the standards of ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests," the assessment examines the hair strands rather than the follicles beneath the scalp.

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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
