If a hair or alcohol test is needed, our expertise in hair testing is unmatched, with centers in cities all over the Nation. Typically, 1.5 to 2 inches of hair is needed from the scalp, or body hair can suffice in many instances. Hair tests can detect drugs, alcohol/ETG, or other tailored testing options.
Recently, hair follicle drug testing has become a preferred method due to its extensive detection capability. Many employers, legal systems, and Substance Abuse experts now favor hair tests over traditional urine tests. Employers with strict no-drug policies, courts, and those on probation find hair tests particularly useful. A significant advantage is the extended detection timeline of up to 90 days, ensuring rigorous collection and making it difficult to defeat. Nonetheless, for detecting drug use in the prior 5 days, urine tests remain the gold standard.

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair acts as a repository of a prolonged history of substances by capturing biomarkers in the hair's growing fibers. When acquired near the scalp, hair can yield roughly a 3-month detection window for substances. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment comprising around 200 hair strands (approximately equivalent to a #2 pencil's thickness) closest to the scalp will provide 100mg of hair, the optimal sample for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest determining the specimen's weight on a jeweler's scale. If scalp hair is inaccessible, an equivalent quantity of body hair may be gathered. References to head hair pertain exclusively to scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The primary phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial processing into the laboratory system. This process involves confirming the sample's proper sealing and shipping, assigning a randomly-generated LAN (Laboratory Accessioning Number), and fulfilling any additional data entry not captured by an electronic chain of custody system.
Screening includes an initial rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug use in most samples, a positive screen needs confirmation to be valid in a legal context. All samples presumed positive in Screening require further confirmation.
If a sample shows a presumptive positive result in the Screening phase, additional hair is extracted from the original specimen for Extraction. In this step, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a more complex process.
Confirmation for any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently termed as "hair follicle tests," the test itself examines the hair strand and 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.
