Accredited Drug Testing provides thorough hair follicle drug assessments in Greenbrier, Tennessee. If you're in need of a hair or alcohol test, Accredited Drug Testing is your expert in hair analyses, and we maintain testing facilities across all major U.S. cities for conducting such tests. Typically, 1.5 to 2 inches of hair from your head's crown or other body parts can be used. Hair evaluations can detect drugs, alcohol/ETG, or other tailored options.
The hair follicle drug test has become increasingly prevalent for drug evaluations in recent years. Employers, judicial systems, and Substance Abuse experts now often require hair testing instead of traditional urine tests. Employers with strict no-drug policies, courts, and probation officers utilize these tests. Their greatest advantage is detecting drug usage for an extended period, up to 90 days, using a monitored collection process, making them virtually tamper-proof. However, screenings for recent drug use within the last five days remain more precise with urine tests.

Hair testing is now considered a formidable method for identifying drug and alcohol consumption. Hair records a long-term timeline of drug and alcohol use by encapsulating biomarkers within the strands as they grow. When cut near the scalp, hair can offer roughly a 3-month detection period for alcohol and drug usage. Hair is easy to gather, difficult to tamper with, and straightforward to transport.
A 1.5-inch portion consisting of approximately 200 hair strands (comparable to the thickness of a standard #2 pencil) nearest to the scalp provides 100mg of hair, the preferred quantity for analysis and verification. For EtG, additional analyses or panels exceeding 10, 150mg of hair is advisable. It is best to measure the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be taken. When discussing head hair, it pertains exclusively to scalp hair. Body hair includes all other variants (facial, axillary, etc.).
Process Overview
The key steps in determining the outcome of a lab-based drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial assessment and integration of a sample into a lab's workflow. This step involves ensuring the sample was dispatched securely, assigning a unique LAN (Laboratory Accessioning Number), and completing any requisite data entry not supplied by an electronic chain of custody system.
Screening serves as an initial examination for substance abuse. While Screening economically eliminates drug usage in most cases, a positive finding necessitates confirmation for validity in legal proceedings. Any samples testing presumptively positive during Screening require subsequent verification.
If a specimen results in a presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are separated from the hair at a much more diluted concentration compared to other techniques (such as urine or saliva), highlighting the complexity of hair drug analysis.
Validation of positive results from Screening is done through GC/MS, GC/MS/MS or LC/MS/MS techniques. Any samples that are presumptively positive undergo cleaning prior to confirmation if necessary. The entire process, from Accessioning to Confirmation, is reviewed per the CAP (College of American Pathologists) Hair guidelines and in compliance with ISO / IEC 17025 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.
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.
