Accredited Drug Testing provides extensive hair follicle drug testing services in Williamsville, Virginia. If you're in need of a hair or alcohol screening, Accredited Drug Testing is an expert in hair testing, with facilities in cities across the nation equipped to handle hair analyses. Typically, 1.5 to 2 inches of hair from the head or body is needed. Hair analyses can detect drugs, alcohol/ETG, or can be tailored for other specific testing needs.
Drug testing methods have increasingly involved hair follicle drug testing in recent times. A variety of employers, judicial entities, and substance abuse experts are now opting for hair tests instead of the traditional urine analysis. Hair follicle testing is preferred by employers enforcing strict no-drug policies, legal courts, and probation officers, primarily due to its extended detection timeframe of up to 90 days, making it nearly foolproof to circumvent. Yet, for identifying drug usage within the past five days, the urine test remains unmatched in accuracy.

The utilization of hair testing has emerged as a significant method in identifying drug and alcohol consumption. Hair serves as a long-term registry of alcohol and drug presence by embedding biomarkers within its fibers during growth. When gathered near the scalp, hair offers a detection window of roughly 3 months for alcohol and drugs. The collection process for hair is straightforward, relatively tamper-resistant, and convenient for transport.
A segment of 1.5 inches comprising approximately 200 hair strands (similar in diameter to a #2 pencil) near the scalp yields 100mg, which is optimal for analysis and verification. For EtG, additional screenings, and/or tests exceeding 10 panels, 150mg of hair is preferable. Measuring the sample using a jeweler’s scale is advised. Should scalp hair be absent, an equivalent quantity of body hair can be used. References to head hair exclusively denote scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four primary phases in the laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into the lab’s framework. This stage encompasses ensuring the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any residual data input not facilitated by an electronic chain of custody protocol.
Screening acts as a preliminary assessment for drug presence. Though cost-effective, a positive result in Screening must undergo confirmation for legal validity. Samples yielding a presumptive positive from Screening require subsequent confirmation.
In instances of presumptive positives in Screening, more hair is extracted from the original sample for the Extraction phase. In this phase, drug components are isolated from hair at a concentration considerably lower than found in other methods (e.g., urine or saliva), underscoring hair drug testing’s complexity.
Confirmation of positive screening outcomes is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo cleansing before confirmation if needed. The complete lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 standards.

Note: Commonly referred to as "hair follicle tests", the analysis targets the hair strand itself 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.

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.
