Accredited Drug Testing offers comprehensive hair follicle drug assessments in Charleston, Tennessee. If a hair drug or alcohol screening is required, Accredited Drug Testing excels in this field, with centers across Nationwide capable of administering hair assessments. Typically, 1.5 to 2 inches of hair from the crown or body is necessary. Hair assessments can be customized to check for drugs, alcohol/ETG, or other specific needs.
Lately, hair follicle drug tests have become a more common method for conducting drug screenings. Numerous employers, courts, and Substance Abuse experts now favor hair tests over traditional urine tests. This type of drug test is favored by zero-tolerance employers, courts, and probation officers. Its main advantage lies in its extended detection window, up to 90 days, and the observed collection method makes it highly resistant to manipulation. However, for detecting recent drug use within the last 5 days, urine tests remain the most reliable.

Hair assessments are increasingly acknowledged as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of substance intake by embedding biomarkers in the strands of hair in growth. When gathered near the scalp, it can present a detection span of up to three months for substances. Hair collection is uncomplicated, fairly resistant to tampering, and straightforward for transportation.
A sample length of 1.5 inches, consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal quantity for testing and verification. For EtG, additional tests, or panels exceeding 10, a 150mg amount of hair is suggested. We advise measuring the specimen using a jeweler’s scale. If scalp hair cannot be obtained, the same quantity of body hair can be taken. References to head hair pertain solely to scalp hair, while body hair covers all other varieties (face, underarm, etc.).
Process Overview
The laboratory process of analyzing a drug test sample consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's preliminary integration into a lab’s framework. This step verifies proper sealing and shipping, assigns an arbitrarily chosen LAN (Laboratory Accessioning Number), and completes any extra data input absent from an electronic custody chain system.
Screening performs a primary swift analysis for substances of abuse. While Screening offers an economical method for checking drug use in most samples, any positives require confirmation for legal acceptability. Any samples showing presumptive positives in Screening necessitate further confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample for Extraction. During Extraction, substances are derived from hair at notably lower concentrations compared to alternative methodologies (e.g., urine, saliva), making hair drug testing the most challenging to execute.
Verifying any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as necessary. The complete lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation.

Note: Commonly referred to as "hair follicle tests", these evaluations analyze 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
