Accredited Drug Testing provides comprehensive hair follicle drug tests in Wall, Texas. When needing a hair drug or alcohol exam, Accredited Drug Testing specializes in this area, with testing facilities available across all U.S. cities to conduct a hair analysis. For most tests, 1.5 to 2 inches of hair from the head or body can be utilized. Hair samples can be evaluated for drug use, alcohol/ETG, or other specialized testing options.
Recently, drug testing techniques increasingly include hair follicle drug assessments. More employers, judicial systems, and substance abuse experts insist on hair drug tests over traditional urine exams. Employers with zero-tolerance policies, the courts, and individuals on probation favor hair follicle tests for their extended detection capacity, typically covering up to 90 days and collected through an observed process that is hard to cheat. Nevertheless, for ingestion within the past 5 days, urine testing remains the most precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is now recognized as a potent method for detecting drug and alcohol usage. Hair offers an extended timeline of alcohol and other drug consumption by capturing biomarkers in the strands of the growing hair. When collected near the scalp, hair provides an approximately 3-month detection period for alcohol and other drugs. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch sample with approximately 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample size for both screening and confirmation. For EtG, extra tests, and/or over 10-panel tests, a 150mg specimen is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is not available, a similar quantity of body hair can be collected. When mentioning head hair, it strictly refers to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the laboratory involves these four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample within the laboratory’s system. This step involves confirming the sample was correctly sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not covered by an electronic chain of custody system.
Screening is the preliminary rapid assessment for drugs of abuse. While Screening offers a budget-friendly means to dismiss drug use in the majority of samples, a positive screen must be confirmed for court admissibility. Any samples that are tentatively positive during Screening require secondary confirmation.
If a sample results in a tentative positive during the Screening phase, additional hair is extracted from the initial specimen for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than seen in other procedures (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The completed laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often termed "hair follicle tests", the actual 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.
