Accredited Drug Testing offers comprehensive hair follicle drug testing services throughout Cedar Creek Lake, Texas. If seeking a hair or alcohol test, Accredited Drug Testing's specialization in hair analysis is unparalleled, with facilities nationwide ready to conduct tests. Generally, hair length of 1.5 to 2 inches on the scalp or body suffices. Our tests can identify drugs, alcohol/ETG, or cater to specific testing needs.
In recent times, hair follicle drug tests have become increasingly prevalent for drug screenings. Employers, courts, and substance abuse experts now prefer hair drug tests over urine tests. Employers adhering to zero-tolerance drug policies, courts, and probationers often rely on this method. The key advantage of hair tests is their extended detection window for drug usage, typically up to 90 days, with an observable collection method that's nearly foolproof against tampering. However, urine tests remain superior for identifying recent drug use within five days.

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drug intake by embedding biomarkers within the fibers of growing hair. When acquired near the scalp, it offers up to a roughly 3-month period of detection for alcohol and drugs. Hair sample collection is straightforward, relatively tamper-proof, and uncomplicated to transport.
Taking a 1.5-inch segment of approximately 200 hair strands (equivalent in breadth to a #2 pencil) nearest to the scalp yields 100mg, the optimal quantity for both screening and confirmation. When dealing with EtG, add-ons, and/or panels exceeding 10, a 150mg sample is advisable. We suggest measuring the specimen with a jeweler's scale. If there's no scalp hair, a comparable volume of body hair can be used. 'Head hair' refers specifically to scalp hair, while 'body hair' includes all other types (facial, axillary, etc.).
Process Overview
The major stages in lab-based processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning concerns the initial handling of a specimen within a lab's framework. This phase ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes additional data input unprovided by an electronic custody system.
Screening entails a preliminary rapid evaluation for substance misuse. While Screening is an economical method for excluding drug use in most samples, confirmed positive screens are needed for court validity. Any samples Indicatively positive at Screening need further confirmation.
In instances where a specimen is provisionally positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. At this phase, drugs are pulled from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
Confirmation of any provisional positive screenings involves techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, every provisional positive sample undergoes washing as essential. The entire laboratory sequence from Accessioning to Confirmation is under review guided by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Limitations:
Note: Despite being labeled "hair follicle tests", the test analyzes the hair strand itself, rather than the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
