Accredited Drug Testing offers comprehensive hair follicle drug testing in Texarkana, Texas. For those requiring a hair drug or alcohol test, Accredited Drug Testing has expertise in hair testing and maintains testing centers across all cities nationwide to conduct such tests. Typically, 1.5 to 2 inches of hair from the crown of the head or body is needed. Hair tests can be tailored to analyze drugs, alcohol/ETG, or other specific hair testing options.
Recently, hair follicle drug testing has become more popular in drug testing methodologies. Employers, court systems, and substance abuse professionals are increasingly opting for hair drug tests over traditional urine tests. Hair follicle drug tests serve employers with zero-tolerance drug policies, courts, and probationary individuals. The key advantage of hair follicle drug tests is their extended detection period of up to 90 days, collected in an observed environment, making it nearly irrefutable. Nevertheless, for detecting drug use within the last 5 days, urine tests remain more 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.
The use of hair testing has evolved into an effective method for identifying drug and alcohol consumption. Hair offers a prolonged history of drug and alcohol intake by embedding biomarkers within the fibers of the growing hair strand. When taken near the scalp, hair can offer up to an approximate three-month period for detecting alcohol and other drugs. Hair collection is straightforward, moderately hard to tamper with, and simple to transport.
A 1.5-inch portion of about 200 hair strands (roughly equivalent to a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample for testing and corroboration. For EtG, added tests, and/or assessments exceeding 10 panels, 150mg of the specimen is advised. Using a jeweler's scale for measuring the specimen is recommended. If no scalp hair is available, a similar volume of body hair can be gathered. References to head hair are exclusively about scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
Drug test result processing in the lab consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a lab's system. This step entails confirming the correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data entry not provided by an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. Though Screening offers a cost-effective approach to dismiss drug usage for most samples, a court-admissible result demands confirmation of a positive screen. Samples that test presumptively positive during Screening need a secondary confirmation.
If a sample demonstrates a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. During this stage, drugs are separated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology to execute.
Confirming any positive screening result is done via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as necessitated. The thorough laboratory process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Limitations:
Note: Though frequently labeled as "hair follicle tests", the examination focuses on the hair strand rather than the hair 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.
