Accredited Drug Testing provides comprehensive hair follicle drug assessments in Lufkin, Texas. Whether you seek a hair drug test or alcohol analysis, we specialize in hair testing with facilities across the Nation fully-equipped for the task. Typically, 1.5 to 2 inches of crown or body hair is required. Our tests can assess for drugs, alcohol/ETG, as well as other tailored hair testing services.
Recently, hair follicle drug tests have become a more prevalent choice for drug assessments. Employers, courts, and Substance Abuse experts often opt for hair tests over traditional urine tests. Ideal for zero-tolerance drug policies and legal or probation cases, the main advantage is their extended substance detection period, up to 90 days, with direct collection under observation. However, for detecting recent drug use within the last 5 days, urine tests remain the most precise.

Hair testing is now recognized as a robust instrument for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and other substances by capturing biomarkers within the strands of growing hair. When clipped close to the scalp, hair can offer up to about a three-month window for detecting alcohol and drugs. Hair is straightforward to obtain, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal amount for both screening and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, a specimen of 150mg is advised. It is recommended to weigh the specimen using a jeweler’s scale. If no scalp hair is available, an equivalent amount of body hair may be used. Mention of head hair refers exclusively to scalp hair. Body hair includes any other types of hair (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the laboratory’s system. It includes checking that the sample was securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input that isn't provided by an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. While Screening is an economical method to exclude drug use for most samples, a positive outcome requires confirmation to be valid in court. Samples that are presumptively positive in Screening require additional confirmation.
If a sample tests presumptively positive during the Screening phase, more hair is taken from the original specimen for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluids), making hair drug screening the most complex methodology to execute.
Confirmation for any positive Screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. From Accessioning to Confirmation, the complete laboratory process is evaluated under the CAP (College of American Pathologists) Hair designation and with accreditation to ISO / IEC 17025 standards.

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.
