In Tahlequah, Oklahoma, Accredited Drug Testing offers comprehensive hair follicle drug testing. If you require a drug or alcohol evaluation using hair samples, this specialized service is available in numerous cities nationwide. Typically, 1.5 to 2 inches of hair from the head or body are sufficient for the analysis, which can detect drugs, alcohol/ETG, and offer customized testing options.
Recently, hair follicle drug tests have become more common for drug screenings. Employers, judicial systems, and substance abuse specialists prefer this method over traditional urine tests. These tests are favored by organizations with zero-tolerance drug policies due to their extended detection window, lasting up to 90 days. It's also almost impossible to tamper with. However, for detecting recent drug use within 5 days, urine tests remain more precise.

Hair analysis is increasingly recognized as a potent means for identifying drug and alcohol consumption. Hair captures a prolonged account of alcohol and drug use by embedding biomarkers within the fibers of the hair shaft as it grows. When cut near the scalp, hair can reveal usage information from up to around three months for substances like alcohol and drugs. Hair is straightforward to gather, tough to tamper with, and convenient for transport.
A 1.5-inch sample of roughly 200 strands (approximately the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional panels beyond 10, or testing expanded panels, it is advised to obtain 150mg of the sample. We suggest measuring the sample with a jeweler's scale for accuracy. In the absence of scalp hair, a corresponding quantity of body hair may be utilized. When discussing head hair, we mean scalp hair specifically. Body hair encompasses other types of hair (facial, axillary, etc.).
Process Overview
The process in the laboratory for a drug test outcome consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into the laboratory's system. This step includes ensuring that the sample is sealed and shipped accurately, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input not provided by electronic means.
Screening conducts a preliminary check for substances of abuse. Although Screening is an economical approach for excluding drug usage in most samples, a positive screen must be corroborated for court acceptance. Samples with presumptive positives from Screening require secondary confirmation.
If a sample tests presumptive positive in Screening, additional hair is retrieved from the original specimen for Extraction. At this stage, substances are extracted from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluids), which is why hair substance analysis is the most challenging to execute.
Confirmation of any positive result from Screening uses GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positive are cleaned prior to confirmation if necessary. The comprehensive laboratory workflow, from Accessioning to Confirmation, is monitored under the CAP (College of American Pathologists) Hair listing and the compliance 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.
