Accredited Drug Testing provides comprehensive hair follicle testing services in King, North Carolina. For those in need of a hair drug or alcohol test, turn to Accredited Drug Testing, which focuses on hair analysis and has testing centers across the nation, ready to perform hair assessments. Typically, 1.5 to 2 inches of hair from the head or body is sufficient for testing. Hair assays can be customized to detect drugs, alcohol/ETG, or other specific needs.
In recent times, hair follicle testing has become a more prevalent choice in drug testing methods. Many workplaces, judicial systems, and substance abuse experts now opt for hair testing over conventional urine tests. Hair follicle tests are ideal for employers enforcing no-drug policies, courts, or those on probation. This method's key advantage is its prolonged detection ability, extending up to 90 days, collected under direct supervision, making it extremely difficult to tamper with. That said, for detecting recent drug use within the last five days, urine tests remain the most precise.

Hair testing is increasingly recognized as an effective means of identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drug intake by encasing biomarkers within the hair shaft's fibers. When hair is taken from the area closest to the scalp, it can reveal drug and alcohol use for roughly 90 days. Hair collection is straightforward, hard to falsify, and convenient to transport.
A hair sample taken near the scalp, measuring 1.5 inches and consisting of around 200 strands (about the thickness of a #2 pencil), will yield 100mg, which is the ideal sample size for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a quantity of 150mg is advisable. Using a jeweler's scale for measuring the specimen weight is suggested. If scalp hair is unavailable, an equivalent amount of body hair can be taken. In mentioning head hair, we specifically mean scalp hair, whereas body hair includes all other types, such as facial and axillary hair.
Process Overview
The four key stages in the analysis of a drug test result by a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab's database. This phase ensures the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not captured by the electronic chain of custody system.
Screening is a preliminary check for drug consumption. Though Screening is an economical method to exclude drug consumption in most samples, a positive screen must be authenticated to hold legal validity. Any samples indicating a presumptive positive during Screening need further confirmation.
If Screening suggests a positive result, additional hair is extracted from the original sample for further processing. In Extraction, drugs are isolated from hair at significantly lower concentrations compared to other procedures (like urine or oral fluids), highlighting the complexity of hair drug testing.
GC/MS, GC/MS/MS, or LC/MS/MS is utilized for the Confirmation of any positive screening outcomes. Presumptive positive samples are washed before confirmation when necessary. From Accessioning through Confirmation, the laboratory procedure is scrutinized under both CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation standards.

Note: Although often termed as "hair follicle tests", the test itself targets the hair shaft and not 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.
