In Longview, North Carolina, Accredited Drug Testing offers comprehensive hair follicle drug screenings. For those needing hair or alcohol testing, our specialty lies in hair tests, with centers available in all major cities across the country, ready to conduct hair analysis. Most individuals require 1.5 to 2 inches of hair from the crown or body for testing. We can screen for drugs, alcohol/ETG, or offer personalized hair testing solutions.
Recently, the approach for conducting drug tests has increasingly included hair follicle examinations. This method is gaining acceptance among employers, judicial systems, and Substance Abuse experts who prefer it over urine tests. Employers enforcing zero-tolerance drug policies, judicial entities, and probationers frequently opt for hair follicle tests. Their main advantage is the extended detection timeline, typically up to 90 days; these tests are collected in a supervised setting, making them nearly tamper-proof. Nevertheless, urine tests provide superior accuracy for detecting usage within the previous five days.

Hair evaluation is now recognized as an effective method for identifying the consumption of drugs and alcohol. Biomarkers from alcohol and other substances become embedded in the fibers of the hair as it grows, providing a prolonged record of usage. When taken close to the scalp, hair can offer a detection period of up to around three months for alcohol and other substances. Collecting hair is uncomplicated, not easily tampered with, and convenient to transport.
A sample length of 1.5 inches, comprising about 200 strands of hair (roughly the size of a #2 pencil) proximal to the scalp yields 100mg of hair, which is optimal for evaluation and confirmation. For EtG, extra tests, and/or screenings exceeding ten panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to measure the sample weight. If scalp hair is not available, an equivalent quantity of body hair may be collected. The term head hair denotes scalp hair solely, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The essential steps in laboratory processing for drug test evaluation are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample in a laboratory system. It involves confirming that the sample was appropriately sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any leftover data entries missing from an electronic chain of custody system.
Screening entails a superficial scan for substance abuse. While it is a cost-efficient strategy to exclude substance usage in most samples, a verified positive requires confirmation for admissibility in legal contexts. Any sample that indicates a presumptive positive in Screening necessitates further confirmation.
If Screening suggests a presumptive positive result, more hair is collected from the original specimen for the Extraction phase. Here, the extraction of substances from hair occurs at a considerably lower concentration compared to other methods (such as urine or oral fluids), highlighting the challenge of executing hair drug testing.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples indicating presumptive positivity undergo necessary pre-washing. The comprehensive laboratory workflow from Accessioning to Confirmation is scrutinized in line with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although colloquially referred to as "hair follicle tests," the evaluation actually examines the strand rather than the follicle beneath the scalp.
Hair follicle testing in Longview, NC, demonstrates several advantages over traditional urine testing. One of the primary benefits is its enhanced detection accuracy and reliability.

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.
