Delivering comprehensive hair follicle drug testing services throughout Saint John, Washington, Accredited Drug Testing is a leader in the field. For those requiring hair drug or alcohol testing, we offer specialized hair follicle testing and operate centers nationwide. Typically, 1.5 to 2 inches of hair from the scalp or body suffices for testing. Hair analyses can include drugs, alcohol/ETG, or other tailored options.
Recently, drug testing methods have increasingly adopted hair follicle analysis. Employers, courts, and substance abuse experts are opting for hair tests over conventional urine tests to enforce zero-tolerance policies. Unlike urine tests, hair follicle assessments provide up to a 90-day drug detection window, are overseen in a controlled environment, and are nearly foolproof. However, urine testing remains most effective for detecting recent drug use within 5 days.

Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair captures a chronological record of alcohol and drug use by embedding biomarkers within the strands of hair as it grows. When gathered near the scalp, hair can offer about a 90-day detection period for alcohol and other substances. Hair collection is straightforward, relatively tamper-proof, and easily transportable.
A sample measuring 1.5 inches consisting of around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for initial screenings and verifications. For EtG, additional tests, or examinations exceeding 10 panels, 150mg of hair is advised. We suggest using a jeweler's scale to determine the weight of the sample. If scalp hair is not available, an equivalent amount of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory process of handling a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is logged into the laboratory’s system. This process involves ensuring the sample was sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data requirements absent from an electronic chain of custody system.
Screening performs a rapid assessment for drug presence. Although Screening is an economical method to dismiss drug involvement in most cases, a positive result necessitates subsequent confirmation for legal admissibility. Samples testing presumptively positive in Screening need further confirmation.
If the Screening indicates a presumptive positive outcome, extra hair is extracted from the primary sample and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than those found in other methods (such as urine or oral fluid), contributing to hair drug screening being the most challenging method to execute.
Verification of any positive screening result is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all samples presumed positive are washed as required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

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.
