Accredited Drug Testing provides thorough hair follicle drug tests in Sheppard, Arkansas. Should you require a hair drug or alcohol screening, Accredited Drug Testing specializes in this area, with testing facilities available in every city across the nation. Typically, you need 1.5 to 2 inches of hair from the crown or body for testing. Hair tests can detect drugs, alcohol, or be customized for other substances.
Over recent years, drug testing methods have increasingly incorporated hair follicle analysis. Employers, courts, and Substance Abuse experts increasingly demand hair drug testing over the more conventional urine tests. Hair tests, favored by employers with zero-tolerance policies, courts, and probationary services, offer a major advantage of a longer detection window—up to 90 days—along with observed sample collections reducing cheating. For drug detection within the past 5 days, traditional urine tests remain most precise.

Hair analysis is now recognized as an effective resource for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and substance intake by embedding biomarkers within the strands of growing hair. When gathered close to the scalp, hair samples can present an approximate 3-month window for detecting alcohol and other substances. Hair collection is straightforward, not easily tampered with, and convenient for shipping.
A sample measuring 1.5 inches, containing around 200 strands (roughly the size of a #2 pencil) from the scalp, will produce 100mg of hair, which is the ideal amount for both initial testing and follow-up confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing the sample is recommended. In cases where scalp hair cannot be obtained, a similar quantity of body hair can be utilized. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into the lab’s system. This phase includes ensuring the sample was sealed and transported correctly, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any data entry omitted by an electronic chain of custody system.
Screening entails a preliminary examination for substances of abuse. Although Screening is an economical method to exclude drug use in most samples, a positive result must be validated to stand in legal settings. All samples showing a presumptive positive in Screening need a secondary confirmation.
If a sample exhibits a presumptive positive during Screening, additional hair is extracted from the original sample and processed for Extraction. In this phase, drugs are removed from hair at far lower levels than in other methods (such as urine or oral fluid), which accounts for the complexity of hair drug analysis.
Any positive outcome from Screening is validated through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo cleaning before confirmation as necessary. The entire lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often termed as "hair follicle tests", the analysis is conducted on the hair strand and not the hair 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.
