Our expertise in hair drug and alcohol testing is extensive, with facilities conveniently located across the country ready to conduct tests. Typically, 1.5 to 2 inches of hair is required from the scalp or other parts of the body for testing. Hair testing can effectively screen for drugs, alcohol/ETG, and other specific needs.
The method of drug testing has increasingly shifted towards using hair follicle analysis in recent years. Employers, judicial systems, and substance abuse specialists are opting for hair tests rather than traditional urine analyses. Businesses with strict anti-drug policies and courts utilizing probation services benefit significantly. The extended detection capability, usually reaching 90 days, ensures accuracy, is difficult to manipulate, and involves observable collection procedures. Nonetheless, for drug use within a recent 5-day window, urine tests remain the most reliable.

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of maturing hair, it offers a prolonged historical account of alcohol and other substance use. When sourced near the scalp, hair can present a detection period of up to roughly 90 days for drugs and alcohol. Obtaining hair is straightforward, moderately hard to tamper with, and simple to transport.
A 1.5-inch sample containing approximately 200 strands of hair (roughly the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for initial testing and verification. For EtG, additional components, and/or more than 10-panel tests, 150mg of the sample is advised. It is advisable to weigh the specimen using a jeweler’s scale. Should scalp hair not be accessible, an equivalent quantity of body hair can be gathered. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (such as facial and axillary).
Process Overview
The laboratory procedure of processing a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing within a laboratory's system. This entails confirming the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.
Screening involves a preliminary assessment for drugs of misuse. While Screening is an economical method to exclude drug use in the majority of samples, a positive screening result requires confirmation for legal admissibility. Samples with a positive screening outcome necessitate secondary verification.
If a sample tests positive during the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are separated from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.
Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test positive are cleaned before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.

Note: While frequently termed as "hair follicle tests", the examination analyzes the hair strand and not the follicle situated 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
