Accredited Drug Testing offers comprehensive hair follicle drug testing services in Nashville, Arkansas. Those seeking a hair drug or alcohol test can rely on Accredited Drug Testing as experts in hair testing, with facilities available across the nation to perform these tests. Typically, a hair length of 1.5 to 2 inches on the head or body is required. Hair samples can be examined for drugs, alcohol/ETG, or other tailored testing options.
The usage of hair follicle drug tests has markedly increased in recent years for drug testing. Many workplaces, judicial entities, and substance abuse experts now prefer hair tests over traditional urine tests. Employers with zero-tolerance drug policies, courts, and those on probation are utilizing these tests, which offer a detection period of up to 90 days, feature an observed sample collection, and are challenging to circumvent. However, for drug use within the preceding 5 days, urine tests remain highly accurate.

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. The hair captures a prolonged substance use history by embedding biomarkers within the fibers as they grow. When hair is sourced near the scalp, it offers about a 90-day detection period for alcohol and drugs. Hair is straightforward to collect, hard to tamper with, and simple to transport.
A 1.5-inch section comprising roughly 200 strands of hair (approximately akin to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmation processes. For EtG, extra markers, and tests beyond 10 panels, a 150mg quantity of the sample is advisable. It is suggested to use a jeweler’s scale to weigh the sample. Should scalp hair be unavailable, a comparable quantity of body hair may be taken. Note that 'head hair' denotes scalp hair alone, whereas 'body hair' encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample’s initial integration into the lab’s system. This encompasses checks on proper sealing and shipping, issuing a random LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic chain of custody system.
Screening provides a preliminary evaluation for substance abuse. Despite being a cost-effective approach to exclude drug use in most samples, a positive screen requires confirmation to be court-admissible. Presumptive positives in Screening necessitate a subsequent confirmation.
If the Screening step results in a presumptive positive, more hair is extracted from the original sample and readied for Extraction. During this phase, drugs are drawn from the hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any positive results from screening occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair standards and accredited ISO / IEC 17025 norms.
Advantages of hair drug testing:
Limitations:
Note: Though frequently termed "hair follicle tests," these tests examine the hair strand itself rather than the follicle beneath the scalp.
Why Hair Follicle Testing Beats Urine Testing in Nashville, AR

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.
