Accredited Drug Testing offers comprehensive hair follicle drug testing in Yellville, Arkansas. Whether you require a hair drug or alcohol test, Accredited Drug Testing is a leader in hair testing, with centers nationwide capable of performing these tests. Typically, 1.5 to 2 inches of hair from your crown or body can be used. Hair tests can detect drugs, alcohol/ETG, or offer other specialized hair testing solutions.
Over the years, hair follicle drug tests have become a more common method for conducting drug screenings. Many employers, courts, and substance abuse specialists now prefer hair tests over standard urine tests. This method is ideal for employers with zero-tolerance policies, courts, and those on probation. Its main advantage is the extended detection window for drug usage, which lasts up to 90 days, collected under observation, and is difficult to manipulate. However, urine tests remain the preferred method for detecting recent drug use within the past five days.

The analysis of hair has emerged as an effective method for detecting the use of drugs and alcohol. Hair captures a long-term record of alcohol and drugs by incorporating biomarkers in the fibers of the growing hair. When taken close to the scalp, hair can reflect drug and alcohol use over a period of up to three months. It is easy to collect, less prone to tampering, and straightforward to send for analysis.
A 1.5-inch portion made up of around 200 strands (about the thickness of a standard pencil) from near the scalp offers about 100mg of hair, which is the best sample size for initial screening and verification. For EtG, additional tests, and/or panels exceeding ten, 150mg is suggested. Utilizing a jeweler’s scale is recommended for accurate measurement. If scalp hair isn't available, a corresponding amount of body hair can be used. "Head hair" specifically refers to hair from the scalp. "Body hair" covers all other hair types (such as facial or armpit hair).
Process Overview
The laboratory processing of a drug test involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes entry into the laboratory’s system. This step includes confirming that the sample was properly secured and transported, generating a random LAN (Laboratory Accessioning Number), and finalizing any data entry not automatically included by an electronic chain of custody system.
Screening is an initial assessment to detect drug abuse. Although Screening is an economical method to exclude drug consumption in most tests, a positive outcome must be validated for legal acceptability. Tests indicating a presumptive positive during Screening need additional verification.
For samples showing a presumptive positive at the Screening phase, more hair is extracted from the main sample for the Extraction process. Here, drugs are isolated from hair at significantly lower concentrations than other techniques (e.g., urine or saliva), which makes hair testing one of the most challenging methods to execute.
Verification of positive results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Every sample presumed positive is washed before confirmation as required. The whole laboratory procedure from Accessioning to Confirmation is reviewed following both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests," this procedure analyzes the hair strand rather than 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.
