Accredited Drug Testing offers comprehensive hair follicle drug testing services in Cross Plains, Tennessee. If a hair drug or alcohol test is your requirement, look no further than Accredited Drug Testing. We are experts in hair testing and have centers throughout Nationwide including all cities capable of conducting a hair test. A hair length of 1.5 to 2 inches on your head or body is typically needed. Hair tests can detect drugs, alcohol/ETG, or be tailored for specific testing requirements.
In recent years, drug testing methods have increasingly adopted the hair follicle drug test. A growing number of employers, courts, and Substance Abuse specialists favor a hair drug test over the traditional urine test. Zero-tolerance policy employers, judicial systems, and individuals on probation often rely on hair follicle drug tests. Their advantage lies in the ability to detect drug use over a much extended period, often up to 90 days, with collection occurring in an observed process, making it nearly tamper-proof. Nevertheless, urine tests maintain their accuracy for drug use detection within the last 5 days.

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged history of substances by encapsulating biomarkers within the strands' fibers. When sourced near the scalp, hair can reveal usage up to a timeframe of about 3 months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp provides 100mg, the optimal sample for both screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, a specimen of 150mg is suggested. It is advised to measure the specimen using a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair may be gathered. When referencing head hair, it pertains strictly to scalp hair. Body hair denotes all other hair forms (facial, axillary, etc.).
Process Overview
The four primary phases in the lab handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a specimen into a lab’s system. This process involves confirming that the sample is sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any further data entry not covered by an electronic chain of custody system.
Screening consists of a preliminary rapid check for substances of abuse. Although Screening is a budget-friendly method to exclude drug use on most specimens, a positive result must be confirmed for it to be valid in court. Any samples that test presumptively positive during Screening require an additional confirmation.
Should a sample test presumptively positive during Screening, further hair is extracted from the original specimen and processed for Extraction. In this stage, substances are isolated from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), which renders hair drug analysis the most challenging technique.
Confirmation of any positive Screening result is achieved through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Note: Despite being called "hair follicle tests", the analysis is conducted on the hair strand and not on 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. 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.
