In Nichols Hills, Oklahoma, Accredited Drug Testing provides comprehensive hair follicle drug testing. Specializing in hair drug and alcohol tests, we have centers nationwide that perform these tests. Hair from the crown or body, typically between 1.5 to 2 inches, is required. Tests can screen for drugs, alcohol/ETG, or other specific substances.
Recently, hair follicle drug testing has become more prevalent. It is favored by employers, courts, and Substance Abuse professionals over urine tests. Employers with zero-tolerance policies, courts, and probation officers often prefer it. The main advantage is its extended detection window of up to 90 days and its secure, observed collection process. While effective, it's less suitable for detecting drugs used within the last 5 days, where urine tests are preferred.

The utilization of hair testing has emerged as a significant method for detecting drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within its strands. When hair samples are obtained near the scalp, they can reveal drug and alcohol presence for approximately a 3-month period. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
Obtaining a 1.5-inch piece of about 200 hairs (roughly the width of a #2 pencil) from the scalp will yield approximately 100mg, which is the optimal quantity for both screening and validation. For EtG, add-ons, or tests exceeding 10 panels, a sample size of 150mg is advisable. It's suggested to use a jeweler's scale for measuring. In the absence of scalp hair, an equivalent quantity of body hair may be used. Reference to head hair pertains solely to scalp hair. Body hair includes all other types, such as facial and axillary hair.
Process Overview
The main stages in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample into the lab's database. This step ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry absent from the electronic chain of custody.
Screening serves as a rapid preliminary examination for drugs of abuse. Although Screening is cost-effective for dismissing drug use in numerous samples, a positive result necessitates confirmation to be court-admissible. Presumptive positive samples in Screening proceed to secondary verification.
In cases of presumptive positive results during Screening, additional hair is extracted and readied for Extraction. This stage involves reducing drug concentration levels from hair more significantly than other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive Screening results. All positive samples undergo washing before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is scrutinized according to the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Even though termed 'hair follicle tests', the test analyzes the hair strand, not the 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.
