Whether for drugs or alcohol, we specialize in hair testing and have numerous centers across the nation capable of performing these tests. Typically requiring 1.5 to 2 inches of hair from the head or body, our hair tests are versatile and can identify drugs, alcohol/ETG, or other custom hair testing options.
Recently, hair follicle drug testing has become a preferred method for drug screening. It's favored by employers, judicial systems, and substance abuse professionals over standard urine tests. Particularly valued by organizations with strict no-drug policies, hair tests cover a longer detection period of up to 90 days, are conducted under observation, and are difficult to falsify. For detecting recent drug use, within five days, urine tests remain most accurate.

Hair testing has emerged as a potent method for discerning drug and alcohol use. Hair offers a comprehensive timeline of alcohol and drug consumption by embedding biomarkers within the strands of the growing hair. When procured from near the scalp, hair can present up to an approximately three-month detection window for alcohol and drugs. Collecting hair is straightforward, relatively tough to tamper with, and simple to transport.
A sample measuring 1.5 inches, comprising around 200 hair strands (comparable to a #2 pencil's thickness) from the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is suggested. Utilizing a jeweler’s scale to weigh the sample is recommended. Should scalp hair be unavailable, an equivalent quantity of body hair may be gathered. When mentioning head hair, it specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result entails four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory’s system. This step involves ensuring the sample was securely sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and conducting any further data input not covered by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for drugs of abuse. While Screening serves as an economical approach to exclude drug use on most samples, a positive result requires confirmation to be legally valid. Any samples that show presumptive positives in Screening necessitate a follow-up confirmation.
If a sample shows a presumptive positive during Screening, additional hair is extracted from the initial specimen and readied for Extraction. In this step, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly complex to execute.
Confirmation of any positive Screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as needed. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand rather than the scalp's hair follicle.

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.
