If you require drug or alcohol testing through hair samples, Accredited Drug Testing is equipped with centers nationwide, including all cities, to conduct this form of testing. Adequate hair length is 1.5 to 2 inches on the crown or body for testing purposes. Hair samples can be tested for drugs, alcohol/ETG, and other customized requirements.
Hair follicle testing has increasingly become a chosen method for drug testing over recent years. Employers, legal entities, and Substance Abuse specialists are now more inclined to prefer hair drug tests over traditional urine tests. These tests are favored by employers with zero-tolerance policies, courts, and individuals on probation due to their benefits. They offer a detection window of up to 90 days, are conducted under observation, and are difficult to tamper with. For detecting drug use within the past 5 days, urine tests remain the standard.

The utilization of hair testing has emerged as a formidable method for identifying drug and alcohol consumption. Hair strands capture biomolecular evidence within their fibers, providing an extended timeline of substance usage. When acquired in close proximity to the scalp, hair samples can present nearly a three-month detection period for drugs and alcohol. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
Obtaining a 1.5-inch hair sample consisting of approximately 200 strands nearest to the scalp yields 100mg of hair, the optimal quantity for testing and confirmation processes. For EtG or additional tests exceeding 10 panels, a sample weighing 150mg is advised. Utilizing a jeweler’s scale for precise measurement is suggested. If scalp hair cannot be obtained, an equivalent volume of body hair is acceptable. References to head hair imply scalp hair, while body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory procedure for evaluating a drug test result encompasses four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially integrated into a laboratory's system, entailing validation of proper sealing and shipping, allocation of a unique LAN (Laboratory Accessioning Number), and completion of any data entry not facilitated by an electronic chain of custody system.
The Screening phase involves a preliminary assessment for the presence of drugs. This step is a cost-efficient means to exclude drug use in the majority of samples; however, a positive screening necessitates confirmation for court admissibility. Samples yielding presumptive positive results require additional confirmation testing.
In cases of presumptive positivity at the Screening stage, further hair is extracted from the original sample for the Extraction phase, where drugs are isolated at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Positive screening results are substantiated through GC/MS, GC/MS/MS, or LC/MS/MS confirmation techniques. All presumptive positive specimens undergo washing prior to confirmation as required. The comprehensive laboratory workflow, from Accessioning to Confirmation, is evaluated in accordance with both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation criteria.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests," the actual analysis is conducted on 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.
