In Lowell, Arkansas, Accredited Drug Testing provides comprehensive hair follicle drug screenings. Our facilities in cities across the nation can conduct hair drug and alcohol tests. Typically, testing requires 1.5 to 2 inches of hair from the head or body. These tests can reveal drugs, alcohol/ETG, and offer other tailored options.
Recently, drug testing methods increasingly feature hair follicle tests. Employers, legal bodies, and substance abuse specialists prefer these over urine tests. Employers with strict no-drug policies, courts, and probation programs favor hair tests. Their main advantage is the extended detection period of 90 days, collected under supervision, which is extremely difficult to tamper with. However, for drug use within 5 days, urine tests remain more precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing has become a recognized method for identifying drug and alcohol usage. Hair captures a long-term record of substances by entrapping biomarkers within the hair fiber. When collected near the scalp, it offers a detection period of up to three months for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches containing approximately 200 hairs (similar in width to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for test screening and validation. For EtG, additional tests, or tests beyond 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair is unavailable, an equivalent amount of body hair can be used. References to head hair pertain only to scalp hair. Body hair includes other types (facial, axillary, etc.).
Process Overview
The key phases in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with entering a sample into the lab's system. This step ensures the sample was properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody.
Screening offers a preliminary drug abuse check. Though cost-effective for most samples, a positive screen requires confirmation for court admissibility. Presumptive positive samples from Screening need secondary verification.
If Screening presents a presumptive positive, additional hair is extracted from the sample for the Extraction phase. Here, drugs are extracted from hair at lower concentrations than in other methodologies (e.g., urine or oral fluid), which makes hair drug screening notably challenging.
Confirmation of a positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. From Accessioning to Confirmation, the entire lab process is reviewed under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

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.
