Accredited Drug Testing provides comprehensive hair follicle drug evaluations in West Chester, Tennessee. If a hair drug or alcohol assessment is needed, our specialized service in hair testing is available with centers in cities across the country. To perform a test, at least 1.5 to 2 inches of hair from the crown or body is required. This method allows for the detection of drugs, alcohol/ETG, or other custom options.
Hair follicle testing has become a favored method for drug assessments, often replacing standard urine tests. Employers, courts, and Substance Abuse experts are opting for hair tests due to their zero-tolerance drug policies and reliability. The major advantage lies in their extended detection span of up to 90 days, coupled with an observed collection process that minimizes the risk of tampering. Nonetheless, urine tests remain more precise for detecting recent drug use within the past 5 days.

Hair analysis is now viewed as an effective method for detecting drug and alcohol consumption. Hair offers a comprehensive record by preserving biomarkers within the strands. When sourced near the scalp, hair can present roughly a 3-month timeframe for alcohol and other narcotics. Collecting hair is straightforward, tampering is challenging, and transportation is straightforward.
Collecting an approximately 1.5-inch section of around 200 hair strands (equivalent to the girth of a #2 pencil) adjacent to the scalp yields 100mg of hair, the perfect amount for screening and verification tests. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is suggested. We advise utilizing a jeweler’s scale to measure the specimen. If scalp hair is not available, an equivalent weight of body hair may be used. When discussing head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is logged into a lab’s system. This step includes verifying the sample’s seal and shipping, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data input absent in an electronic chain of custody system.
Screening conducts an initial assessment for drugs of abuse. Screening is economical for discarding drug usage in numerous samples, yet a positive result requires confirmation for legal validation. Samples with a presumptive positive in Screening necessitate a follow-up verification.
For samples testing positive in Screening, additional hair is extracted and laid out for Extraction. In this procedure, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or saliva), which accounts for the difficulty in performing hair drug analysis.
Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positive undergo a wash before confirmation as necessary. From Accessioning to Confirmation, the full laboratory workflow is evaluated under both the CAP (College of American Pathologists) Hair guidelines and in compliance with ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is often misused, as the test evaluates 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
