Accredited Drug Testing offers comprehensive hair follicle drug testing services in Windsor, Virginia. When in need of hair drug or alcohol testing, rely on us as specialists, with centers nationwide capable of performing hair analyses. Typically, 1.5 to 2 inches of hair from the crown or body are required. Hair tests can be conducted for drugs, alcohol/ETG, or tailored testing options.
In recent years, hair follicle drug tests have become increasingly common for drug screening, preferred by employers, courts, and substance abuse professionals over urine tests. This method supports zero-tolerance policies and probation requirements. A key advantage is the extended detection period, up to 90 days, combined with an observed collection, making it highly tamper-resistant. Nonetheless, urine tests remain superior for recent drug use within 5 days.

Hair analysis is widely regarded as an effective method for detecting the use of drugs and alcohol. Hair captures a prolonged history of substances by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, it offers approximately a three-month window for tracing alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch section consisting of around 200 hairs (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmatory tests. For EtG, supplementary, and/or tests exceeding 10 panels, a sample of 150mg is suggested. We advocate using a jeweler's scale to weigh the sample. If scalp hair is limited, a similar amount of body hair may be obtained. In this context, head hair pertains exclusively to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within the lab's system. This process ensures the sample is securely sealed and dispatched correctly, allocates a random LAN (Laboratory Accessioning Number), and concludes any leftover data entries not covered by an electronic chain of custody system.
Screening serves as an initial rapid assessment for substances of abuse. It is an economical method to exclude drug usage in most samples, yet a positive result must undergo confirmation to be legally viable. Any samples with a presumptive positive in Screening need further confirmation.
If a sample shows a presumptive positive during Screening, additional hair is extracted from the initial specimen for the Extraction phase. At this point, drugs are isolated from hair at considerably lower concentrations than in alternate methods (e.g., urine or oral fluid), which adds to the complexity of hair drug testing.
Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if necessary. The full lab process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Note: Although commonly termed "hair follicle tests," the procedure examines the hair strand, not the follicle under 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.
