Accredited Drug Testing offers comprehensive hair follicle drug testing services in Liberty, Tennessee. Should you require a hair drug or alcohol test, Accredited Drug Testing is the expert in hair testing with centers nationwide ready to conduct these tests. Typically, 1.5 to 2 inches of hair from the crown or other body parts are needed. Hair samples can be tested for drugs, alcohol/ETG, and other specialized options.
In recent times, hair follicle drug testing has become a preferred method for drug checks. Various employers, judicial systems, and Substance Abuse experts now prefer this over the traditional urine tests. Hair tests are favored by those enforcing stringent drug-free policies and by probation officers. A significant advantage is the extended detection period of up to 90 days, collected under supervision, making it extremely difficult to tamper with. That said, for detecting recent usage within the last five days, urine tests remain the benchmark for accuracy.

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 widely recognized as an effective method for identifying drug and alcohol usage. Hair captures a prolonged history of alcohol and other substances by embedding biomarkers in the strands' fibers as they grow. When taken near the scalp, hair can offer approximately a 3-month detection range for alcohol and other drugs. Hair collection is straightforward, fairly resistant to tampering, and simple to transport.
A sample measuring 1.5 inches with roughly 200 strands of hair (resembles the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels above 10, a sample of 150mg is advised. We suggest using a jeweler’s scale for weighing. If scalp hair isn't accessible, a similar quantity of body hair is an alternative. "Head hair" concerns only scalp hair, while "body hair" covers all other types (e.g., facial, axillary).
Process Overview
Laboratory processing of a drug test outcome involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a specimen in the lab's system. It includes ensuring the sample's sealing and proper shipping, assigning a unique LAN (Laboratory Accessioning Number), and performing any data entry omitted by an electronic chain of custody.
Screening means an initial rapid assessment for substance abuse. Although Screening is a budget-friendly approach to dismiss drug use in most samples, a positive screening still requires confirmation for court validity. Presumptive positive samples in Screening need a secondary verification.
For presumptive positives detected in Screening, more hair is drawn from the original sample and readied for Extraction. In this phase, drugs are extracted from hair with less concentration than in alternative methodologies (e.g., urine or oral fluid), highlighting hair drug screening as the hardest method to execute.
A GC/MS, GC/MS/MS, or LC/MS/MS confirms any positive Screening results. Presumptive positive samples are cleansed before confirmation if needed. From Accessioning through to Confirmation, the entire process is scrutinized under both CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Often termed "hair follicle tests," the analysis focuses on the hair strand rather than 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.
