Accredited Drug Testing provides comprehensive hair follicle drug testing services in Perry, Texas. If you're seeking a hair drug or alcohol test, Accredited Drug Testing is an expert in hair testing, with facilities across all cities Nationwide equipped to conduct a hair test. Generally, 1.5 to 2 inches of hair from the head or body suffice. Hair tests can detect drugs, alcohol/ETG, or can be tailored for specific hair testing needs.
The approach to drug testing has increasingly favored hair follicle drug testing in recent years. Hair drug tests are now mandated by many employers, courts, and Substance Abuse professionals as an alternative to standard urine tests. They're preferred by employers with zero-tolerance policies, judicial bodies, and probationers. Hair follicle tests have the advantage of a longer detection window, typically up to 90 days, use an observed collection process, and are extremely difficult to tamper with. That said, for detecting very recent drug use within the last 5 days, urine tests remain the most effective.

Utilizing hair testing is increasingly recognized as an effective method for uncovering drug and alcohol consumption. By capturing biomarkers within the fibers of growing hair strands, hair offers a comprehensive overview of alcohol and drug use over an extended period. When taken near the scalp, hair testing can reveal substance use history for a duration of up to three months. Hair is easy to gather, less prone to tampering, and straightforward to transport.
A hair sample measuring 1.5 inches, consisting of around 200 strands (similar in diameter to a #2 pencil), obtained from the scalp, yields 100mg of hair, which is perfect for both screening and confirmation purposes. For EtG, supplemental tests, or panels exceeding ten, 150mg of hair is advised. Using a jeweler's scale to measure the hair specimen is recommended. If scalp hair cannot be sourced, a comparable amount of body hair may be used instead. Head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial stage, where the sample is incorporated into the laboratory system. This step ensures the sample is adequately sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from the electronic chain of custody system.
During Screening, a preliminary assessment for drug abuse is conducted. While this is a cost-efficient method for excluding drug presence in most samples, any positive screening result must undergo confirmation before being legally valid. Samples showing potential positive results at this stage necessitate additional verification.
Should a sample test presumptively positive during Screening, additional hair is extracted from the existing sample for further processing in the Extraction phase. Here, drugs are separated from hair at relatively lower concentrations compared to other methods like urine or oral fluid testing, which contributes to the complexity of hair drug screening.
Confirmation of any positive screening result is achieved using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating positive results are subjected to washing before confirmation, if necessary. Every step, from Accessioning through to Confirmation, is meticulously reviewed under both the CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 accreditation 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.
