Accredited Drug Testing offers comprehensive hair follicle drug testing services in Dunn, North Carolina. If you’re in need of a drug or alcohol test, we specialize in hair testing with centers available nationwide, including all cities. Typically, 1.5 to 2 inches of hair on your head or body are required for a hair test. Our tests can analyze for drugs, alcohol, or provide customized testing solutions.
Recently, hair follicle drug tests have become more prevalent in drug testing methodologies. They are increasingly used by employers, courts, and substance abuse professionals over traditional urine tests. These tests are favored by employers with zero-tolerance policies, courts, and those on probation. The main advantage is a longer detection window, up to 90 days, with supervised collection, making it very difficult to alter results. However, urine tests remain best for detecting recent drug use within the last five days.

Hair testing is recognized as a significant method for identifying drug and alcohol usage. Hair captures a comprehensive history of substances by embedding biomarkers within the strands as they grow. If taken from the area nearest to the scalp, hair provides an approximate 3-month window for alcohol and drug detection. Its collection is straightforward, tamper-resistant, and simplifies shipping.
A 1.5-inch portion consisting of roughly 200 hairs (equivalent to a #2 pencil thickness) positioned closest to the scalp yields 100mg, deemed the optimal amount for testing and validation. For EtG, supplementary analyses, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's recommended to weigh the hair on a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. In discussing head hair, we specifically mean scalp hair. Body hair includes all other types (such as facial and axillary hair).
Process Overview
The laboratory process of a drug test outcome includes the stages of Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial sample integration into the lab's database. This covers checking the sample seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data not covered by an electronic chain of custody.
Screening performs a preliminary evaluation for drug presence. Although Screening efficiently rules out drug use in most samples, any positive results must be confirmed for court acceptability. Samples with presumptive positives in Screening need subsequent confirmation.
If deemed presumptively positive at the Screening phase, further hair is taken from the original sample for Extraction. Here, drugs are isolated from the hair at much reduced concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies.
GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive Screening findings. Before confirmation, presumptive positive samples are cleansed as necessary. The complete lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: While commonly called "hair follicle tests", the analysis targets the hair strand itself, not 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.
