Accredited Drug Testing provides comprehensive hair follicle drug testing services in South Hill, Virginia. For those needing drug or alcohol tests through hair samples, our expertise lies in this domain and we operate testing centers in cities across the nation that can conduct these tests. A hair length of 1.5 to 2 inches on the head or body is typically required. These tests can identify drugs, alcohol/ETG, or be customized for other substances.
In recent times, hair follicle drug testing is increasingly used as a method for drug screening. Employers, courts, and substance abuse professionals often prefer this test over the traditional urine test. Organizations with zero-tolerance drug policies, courts, and probation services use hair follicle tests. The significant advantage of these tests is an extended detection timeframe of up to 90 days, which is collected securely and is difficult to manipulate. However, for drug use screening within the past 5 days, urine tests remain the most precise.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands of growing hair, providing an extended record of substance use. When collected near the scalp, hair can offer a detection window of up to around three months for alcohol and drugs. The process of collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.
A sample with a length of 1.5 inches consisting of about 200 hair strands (about the thickness of a #2 pencil) taken closest to the scalp will yield 100 mg of hair, which is the optimal sample size for both screening and confirmation. For tests like EtG, additional tests, or those exceeding 10 panels, 150 mg of the specimen is advisable. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair can be collected. The term "head hair" specifically refers to scalp hair; "body hair" encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample within a laboratory’s system. This step ensures that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody.
Screening serves as an initial evaluation for drugs of abuse. While Screening efficiently eliminates drug usage in most samples, any positive results require confirmation to be valid in a legal scenario. Samples that are presumptively positive in Screening must undergo further confirmation.
If a sample shows presumptive positivity during Screening, additional hair from the original sample is gathered for Extraction. This stage extracts drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS or LC/MS/MS technology. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Limitations:
Note: Although commonly referred to as "hair follicle tests", the analysis targets the hair strand rather than 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.
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.
