In Palmersville, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Specializing in hair-based tests, our centers, located in cities nationwide, provide reliable hair drug and alcohol tests. Usually, 1.5 to 2 inches of hair from the scalp or body is required. These tests can detect drugs, alcohol/ETG, or can be customized for specific requirements.
Hair follicle testing has become more prevalent recently, with many employers, courts, and Substance Abuse professionals opting for it over traditional urine tests. Employers with strict drug-free policies, courts, and those on probation commonly use hair tests. The key advantage is a longer detection period—up to 90 days—ensuring accuracy and reducing the chance of tampering. However, urine tests remain more precise for recent drug use within 5 days.

The utilization of hair testing has gained traction as an effective method to detect drug and alcohol consumption. Hair strands offer a comprehensive timeline of alcohol and drug use by embedding biomarkers within the fibers of the developing hair. When procured near the scalp, hair can offer a detection span of up to approximately three months for alcohol and drugs. It is easy to gather, not easily tampered with, and convenient to transport.
A sample about 1.5 inches in length, comprising roughly 200 hair strands (resembling the width of a #2 pencil) nearest to the scalp, typically provides 100mg of hair, which is the optimal quantity for both screening and confirmation testing. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair cannot be obtained, a comparable volume of body hair can be used. References to head hair imply the use of scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a lab's framework. This phase includes ensuring the sample was properly sealed and dispatched, allocating a random Laboratory Accessioning Number (LAN), and finalizing any extra data entry omitted by an electronic chain of custody system.
Screening comprises an initial swift evaluation for substances of abuse. While Screening is a budget-friendly measure to dismiss drug consumption for the majority of cases, a positive result warrants confirmation to be valid in legal proceedings. Samples suggesting a positive outcome in Screening necessitate further verification.
If Screening suggests a positive result, additional hair is extracted from the initial sample and prepped for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening a particularly challenging technique to conduct.
Confirmation of any positive Screening outcome is achieved through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing process before confirmation, as needed. The comprehensive laboratory process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation as well as the accreditation under 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
