In Cedar Hill, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug testing. If a hair or alcohol test is needed, we specialize in hair testing with numerous centers across the nation equipped to conduct these tests. Typically, a hair length of 1.5 to 2 inches on the head or body is required. Hair tests can detect drugs, alcohol/ETG, or other custom options.
Recently, hair follicle drug tests have become more prominent in drug testing procedures. Employers, courts, and substance abuse professionals often opt for hair tests over traditional urine tests. Hair tests are favored by those upholding zero-tolerance policies due to their extended detection period of up to 90 days and the difficulty of tampering. However, urine tests remain more reliable for recent drug use within the last 5 days.

Seen as an effective means for discovering drug and alcohol usage, hair testing utilizes the hair fibers to capture biomarkers, rendering a historical record of consumption. With strands collected near the scalp, the test can detect substances within a roughly 3-month period. The simplicity of hair collection, coupled with its resistance to tampering and ease of shipment, renders it effective.
An ideal sample comprises a 1.5-inch segment of approximately 200 hair strands, equating to the thickness of a #2 pencil, yielding 100mg ideal for screening and confirmation. For testing involving EtG, add-ons, or panels exceeding 10, a 150mg sample is advisable. It is suggested that specimens be weighed using a jeweler’s scale. In the absence of scalp hair, an equal measure of body hair may be substituted. References to head hair pertain solely to scalp hair, while body hair encompasses all other varieties (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes integrating the sample into the lab system, confirming proper sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and completing any additional manual data entry not covered by an electronic chain of custody.
Screening provides an initial examination for substances. While cost-effective for ruling out drug use across most samples, a positive test requires confirmation for court admissibility. Presumptively positive samples from Screening need secondary validation.
Should Screening indicate a presumptive positive result, additional hair from the initial sample is prepared for Extraction. This phase isolates drugs from hair at concentrations significantly lower than those in alternative methods like urine or oral fluid, contributing to the complexity of hair drug screening.
Confirmation for any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing process before Confirmation as deemed necessary. The complete procedure from Accessioning through Confirmation aligns with CAP (College of American Pathologists) Hair criteria and complies with ISO / IEC 17025 standards.

Clarification: Despite being termed "hair follicle tests", the focus is on 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.
