Hair analysis is regarded as a robust means for identifying the consumption of substances such as drugs and alcohol. Hair strands capture biomarkers within their growing fibers, offering a comprehensive history of substance use over an extended period. When collected near the scalp, hair can reveal up to roughly a 3-month detection period for substances like alcohol and drugs. Hair samples are straightforward to gather, relatively challenging to tamper with, and simple to transport.
Acquiring a 1.5-inch portion of around 200 hair strands (comparable to a #2 pencil) close to the scalp provides 100mg of hair, which is the optimal sample size for screening and confirmation purposes. For tests involving EtG, add-ons, or more than 10 panels, a 150mg sample is recommended. It is advisable to weigh the hair sample using a jeweler's scale. If scalp hair is not accessible, an equivalent volume of body hair may be used. The term "head hair" specifically refers to scalp hair. The term "body hair" encompasses all other hair types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result typically involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed within a lab's system. This step ensures the sample was correctly sealed and dispatched, assigns a random Laboratory Accessioning Number (LAN), and finalizes any additional data entry not covered by an electronic chain of custody.
Screening constitutes an initial swift analysis for substances of abuse. While this method is economically efficient for eliminating drug usage in most samples, a positive outcome requires confirmation for court admissibility. Samples showing a presumptive positive in Screening necessitate subsequent verification.
If the Screening phase suggests a positive result, additional hair is extracted from the specimen for the Extraction phase. Here, drugs are extracted from hair at much lesser concentrations compared to other methods (e.g., urine or saliva), making hair drug screening a particularly challenging methodology.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as needed. The complete lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair specifications and accredited per ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests," these tests consider the strand of hair itself, 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.

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
