For comprehensive hair follicle drug testing in Leigh, Texas, rely on Accredited Drug Testing. Our specialty in hair assessment, combined with nationwide centers, ensures accessibility for both drug and alcohol tests. A 1.5 to 2-inch hair length is required, primarily taken from the crown or body. These tests can analyze substances such as drugs and alcohol/ETG, or be tailored for specific needs.
Over recent years, hair follicle drug testing has gained prominence as an alternative to conventional drug testing methods. It is increasingly mandated by employers, judicial systems, and substance abuse counselors instead of urine tests. This testing method, favored by zero-tolerance employers and probation officers, offers a remarkable 90-day detection window. While urine tests remain the gold standard for detecting recent drug use within five days, hair tests promise a virtually foolproof procedure.

Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair captures long-term data of alcohol and drug usage by embedding biomarkers in the fibers of the hair shaft. When sampled close to the scalp, hair offers up to a 3-month detection period for alcohol and drug use. Hair sampling is straightforward, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches and containing about 200 strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for both screening and validation. For EtG, additional tests, and assessments beyond 10 panels, a 150mg sample is suggested. Utilizing a jeweler's scale to measure the sample is advised. If scalp hair isn't available, an equivalent quantity of body hair may be gathered. When discussing head hair, we are specifically referring to scalp hair. Body hair encompasses other hair types (such as facial and axillary hair).
Process Overview
The processing of a drug test result in the lab involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial entry of a sample into a laboratory system. This process ensures that the sample was sealed and transported properly, assigns a unique LAN (Laboratory Accessioning Number), and concludes any remaining data entry not provided via an electronic chain of custody system.
Screening serves as an initial quick assessment for substance abuse. Though Screening is a cost-efficient approach to eliminate drug use in most samples, any positive screening must be validated to be accepted in legal proceedings. Samples that show a presumptive positive result during Screening necessitate further confirmation.
If a sample shows a presumptive positive in Screening, additional hair is drawn from the original sample and prepared for Extraction. During this phase, substances are extracted from hair at a reduced concentration compared to other methods (like urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirming any positive screening result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation as needed. The entire laboratory process from Accessioning to Confirmation undergoes review as per the CAP (College of American Pathologists) Hair classification and the accreditation to ISO/IEC 17025 standards.

Note: Though commonly called "hair follicle tests", the focus of the test is on the hair shaft and 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.
