Accredited Drug Testing provides comprehensive hair follicle drug analysis in Chancellor, Texas. For those needing a hair substance or alcohol evaluation, we are specialists in hair assessments, with testing facilities across all U.S. cities. Typically, 1.5 to 2 inches of head or body hair is required. Hair tests detect substances, alcohol/ETG, or offer other specialized hair testing choices.
Recently, drug evaluations have increasingly incorporated hair follicle tests. They are preferred by many employers, legal systems, and substance abuse experts over traditional urine tests. Companies enforcing zero-tolerance substance policies, court systems, and those on probation use hair follicle tests. The main advantage is their extended detection window, reaching up to 90 days, with direct observation during sample collection, minimizing cheating risks. However, for detecting recent drug use within 5 days, urine tests remain most precise.

Hair testing is recognized as a significant method for identifying drug and alcohol consumption. Hair acts as a repository of biomarkers, capturing a long-term record of substances within the developing hair fibers. When sampled near the scalp, hair can reveal evidence of alcohol and other substances over a period of up to three months. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch portion containing roughly 200 hair strands (about the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for analysis and validation. For EtG, additional requests, and examinations beyond 10 panels, 150mg of the sample is suggested. We advise verifying the specimen weight using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be used. By head hair, we specify hair from the scalp only. Body hair includes all other hair types (facial, underarm, etc.).
Process Overview
The procedure for laboratory analysis of a drug test outcome consists of four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into the lab's system. It involves ensuring the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing data entry not available from an electronic custody chain system.
Screening serves as a preliminary rapid test for drugs of abuse. Although Screening is cost-effective for dismissing drug use in most samples, a positive result requires confirmation to be legitimate in legal proceedings. Samples with presumptively positive screenings necessitate further confirmation.
Should the Screening process reveal a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are drawn from hair at concentrations substantially lower than found in other methods (e.g., urine or oral fluid), which makes hair drug testing particularly challenging.
Confirmation of a positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumed positive samples undergo washing as necessary prior to confirmation. The laboratory workflow from Accessioning through Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation requirements.

Note: Although commonly termed "hair follicle tests", the actual testing focuses on the hair strand rather than the scalp's follicle.

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.
