Accredited Drug Testing provides comprehensive hair follicle drug assessments in Shepherd, Tennessee. For those requiring a hair drug or alcohol screen, Accredited Drug Testing excels in this domain, with facilities across Nationwide equipped to conduct hair analysis. A minimum of 1.5 to 2 inches of hair from the scalp or body is typically necessary. Hair analyses can examine substances, alcohol/ETG, or be tailored for specific needs.
Recently, hair follicle testing has become more prominent in drug screening procedures. Several employers, judicial systems, and Substance Abuse experts opt for hair testing instead of the typical urine tests. These tests are favored by zero-tolerance employers, legal entities, and individuals serving probation. Their main advantage is a lengthy detection timeline for substance usage, usually extending to 90 days. This method involves a monitored collection, making evasion nearly unfeasible. Yet, for usage within a recent 5-day span, urine tests remain extremely precise.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers in the hair fibers as they grow, hair can offer a comprehensive story of alcohol and substance use over time. When sourced near the scalp, hair samples can reveal alcohol and drug use patterns for up to approximately three months. This method is easy to collect, hard to tamper with, and straightforward to send for analysis.
To ensure accurate screening and verification, a 1.5-inch hair sample with about 200 strands (similar to the size of a #2 pencil) from the area nearest to the scalp is required, totaling 100mg. In instances involving EtG, add-ons, or more complex tests beyond 10 panels, a sample of 150mg is advisable. Utilizing a jeweler’s scale to weigh the sample is recommended. If scalp hair isn't accessible, equivalent body hair can be used. References to head hair pertain strictly to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample's preliminary handling in a lab's system occurs, which includes checking that the sample's packaging and transport were correct, allocating a unique LAN (Laboratory Accessioning Number), and completing any remaining data requirements that aren't covered by an electronic chain of custody.
Screening is a preliminary evaluation for the presence of abused substances. Although Screening serves as a cost-efficient method to exclude drug use in most cases, any positive indication must be verified for legality in court. Samples suggesting a positive result in Screening necessitate further confirmation.
Should Screening suggest a positive result, additional hair is retrieved from the initial sample for the Extraction process. Here, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Positive results from screening are further validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing necessary before confirmation. The complete lab procedure, from intake to confirmation, is rigorously assessed to align with both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly misnamed "hair follicle tests", the examination analyzes the hair strands, not the scalp-residing follicles.

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.
