In Charleston, Missouri, Accredited Drug Testing offers hair follicle drug testing services. Accredited Drug Testing excels in such testing and has facilities nationwide. Typically, 1.5 to 2 inches of hair is needed from the crown or body. Tests analyze drugs, alcohol, and other specific options.
The use of hair follicle drug tests has grown among employers, courts, and substance abuse experts, who prefer them over standard urine tests. This method benefits from a longer detection period of up to 90 days, an observed collection process, and resistance to cheating. However, for recent drug use (within 5 days), urine tests remain more precise.

Hair testing is recognized as an effective means for detecting the use of drugs and alcohol. Hair captures a historical record of alcohol and drug consumption by embedding biomarkers in the fibers of the growing hair. When hair is collected near the scalp, it can offer up to a 3-month timeframe for detection of alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A sample measuring 1.5 inches from about 200 strands of hair (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a sample of 150mg is suggested. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is not accessible, an equivalent amount of body hair can be collected. Referring to head hair pertains exclusively to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into the laboratory's system. This process checks that the sample was properly sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and completes any extra data entry not provided by an electronic chain of custody system.
Screening involves an initial rapid assessment for substances of abuse. Screening is a cost-efficient method to exclude drug use for most samples; however, a positive result requires confirmation to be valid in a legal context. Any samples with presumptive positives in Screening must undergo a secondary confirmation.
If a sample yields a presumptive positive during Screening, additional hair is taken from the original specimen and readied for Extraction. Drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most complex method to execute.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation if needed. The entire lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and accreditation with ISO / IEC 17025 standards.

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.
