Accredited Drug Testing provides comprehensive hair follicle drug assessments in Leasburg, North Carolina. For those requiring a hair drug or alcohol examination, Accredited Drug Testing is a specialist in hair assessments, with centers available nationwide in every city for hair testing. Typically, 1.5 to 2 inches of hair from the crown or body hair can be used. Hair analysis can target drugs, alcohol/ETG, or other tailored testing options.
Recently, hair follicle drug testing has gained popularity as a drug testing method. Employers, courts, and Substance Abuse professionals now often opt for a hair drug test over the usual urine methodology. It's the preferred choice for employers enforcing zero-tolerance policies, as well as courts and probation cases. A key advantage is the lengthier detection window of up to 90 days, based on observed collection, and is almost impossible to manipulate. Nonetheless, for detecting recent use within five days, urine tests remain the most accurate.

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 recognized as an effective method for identifying drug and alcohol consumption. Hair captures a lengthy record of alcohol and drug use by retaining biomarkers in the fibers of the hair as it grows. Collected near the scalp, hair can offer a detection window of up to about three months for alcohol and other substances. It's easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment of approximately 200 hairs (about the diameter of a #2 pencil) near the scalp will yield 100mg of hair, which is the ideal quantity for screening and confirmation. For EtG, additional tests, and/or panels beyond 10, it's advised to gather 150mg of the sample. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't available, a similar quantity of body hair can be used. The term head hair specifically refers to scalp hair. Body hair includes all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the laboratory's system. This step verifies the sample's proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any additional data entry missing from an electronic chain of custody system.
Screening is a preliminary test for drugs of abuse. Although it is a cost-efficient method to eliminate drug usage in most samples, a positive screen must be confirmed to be legally acceptable. Any presumptive positive samples from Screening necessitate a follow-up confirmation.
Should Screening indicate a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at a significantly lower concentration than in other testing methods (e.g., urine or oral fluid), which explains why hair drug testing is especially challenging.
Confirmation of any positive screenings is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo a washing procedure before confirmation if needed. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and adheres to the ISO / IEC 17025 standards.

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.
