For those requiring hair drug or alcohol tests, Accredited Drug Testing has expertise in hair testing, with facilities in every city across the nation equipped to conduct these tests. Generally, 1.5 to 2 inches of hair from the crown or body can be used. These tests can detect drugs, alcohol/ETG, or other specialized hair testing needs.
In recent years, the use of hair follicle drug tests has become more prevalent. Numerous employers, courts, and substance abuse professionals now prefer hair drug tests over standard urine tests. Hair follicle drug tests are chosen by employers with strict no-drug policies, courts, and individuals on probation. A key advantage of this test is its extended detection period for drug use, typically up to 90 days, with sample collection being observed to prevent tampering. However, for detecting recent drug use within the past 5 days, urine tests remain the most precise.

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. It captures a long-term record of substances by embedding biomarkers within the hair as it grows. When sampled near the scalp, hair can offer up to a 3-month period for detecting alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and simple to transport.
A 1.5-inch section consisting of approximately 200 hairs (similar in size to a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal sample for initial screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler's scale for specimen weighing is suggested. If scalp hair is unavailable, a comparable quantity of body hair can be gathered. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (including facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory's system. This process includes verifying the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not included by an electronic chain of custody system.
Screening entails a preliminary assessment for drugs of abuse. Though cost-effective for excluding drug use in the majority of cases, a positive screening requires confirmation for court acceptance. Samples presumed positive in Screening necessitate subsequent confirmation.
If a sample appears positive during Screening, additional hair is taken from the primary specimen and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as required. The laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Note: Often termed "hair follicle tests", the actual analysis is performed on the hair strand, not the follicle 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.
