In Portland, Texas, Accredited Drug Testing provides comprehensive hair follicle drug analysis. Whether seeking testing for drugs or alcohol, our expertise in hair testing is available nationwide. For a hair test, ensure 1.5 to 2 inches of hair from the crown or your body is available. Hair tests can evaluate drug use, alcohol presence, or be customized to specific needs.
The adoption of hair follicle drug tests has increased recently. Employers, legal entities, and substance abuse experts often choose them over traditional urine tests. These tests are favored by zero-tolerance employers, courts, and probationary individuals for their long detection window, up to 90 days. They are collected under observation, making them difficult to tamper with, but for recent drug use within five days, urine tests remain more precise.

Hair analysis has evolved into a robust method for identifying the use of substances like drugs and alcohol. This is because hair incorporates biomarkers within its fibers, offering a long-term overview of substance intake. When procured near the scalp, hair samples can exhibit a detection span of around three months for alcohol and drugs. It's straightforward to gather, relatively hard to tamper with, and effortless to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (equivalent to the girth of a #2 pencil) close to the scalp provides 100mg, serving as the optimal sample for both screening and confirmation. For tests involving EtG, additional screenings, or panels exceeding 10, a 150mg sample is advisable. It's suggested to measure the specimen with a jeweler's scale. Should scalp hair not be accessible, a comparable quantity of body hair can be used. When mentioning head hair here, it strictly pertains to scalp hair. Body hair denotes all other types (such as facial or axillary hair).
Process Overview
Laboratory processing of drug test outcomes follows four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a laboratory’s database. This stage includes confirming the sample’s secure sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry required outside of an electronic chain of custody framework.
Screening involves a preliminary assessment for drug abuse presence. While Screening offers a cost-efficient means to dismiss drug use in many samples, confirming a positive screen is essential for its legal admissibility. Samples showing a presumptive positive in Screening necessitate further confirmation.
Should a sample test presumed positive during Screening, additional hair is requisitioned from the initial sample for Extraction. In this phase, hair undergoes a process to extract drugs at significantly lower concentrations compared to methodologies like urine or oral fluid samples, marking hair drug screening as the most intricate procedure to execute.
Confirmation of any positive Screening results is executed through methodologies such as GC/MS, GC/MS/MS or LC/MS/MS. Presumptively positive samples undergo a washing process before confirmation, as required. The complete laboratory workflow from Accessioning to Confirmation is comprehensively reviewed under the CAP (College of American Pathologists) Hair standards and complies with ISO / IEC 17025 standards accreditation.

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.
