Accredited Drug Testing offers comprehensive hair follicle drug tests in Durham, North Carolina. For both hair drug and alcohol tests, we specialize in hair testing with centers available in every city nationwide. Typically, 1.5 to 2 inches of hair from the crown or elsewhere on the body are acceptable. Our tests can analyze for drugs, alcohol/ETG, or provide custom hair testing solutions.
Over recent years, hair follicle drug testing has become increasingly popular. Many employers, courts, and substance abuse professionals are opting for this method over standard urine tests. Hair follicle tests are favored by employers with strict no-drug policies, courts, and probation cases due to their longer detection period, which can extend up to 90 days, and the difficulty in tampering. For detecting use within 5 days, urine tests remain most accurate.

Hair testing is recognized as an effective means of detecting drug and alcohol use. Hair strands capture a long-term record of substance use by embedding specific biomarkers within the hair as it grows. When hair is collected near the scalp, it can reflect a usage history of alcohol and drugs for as long as three months. Collecting hair is straightforward, not easily tampered with, and can be transported without difficulty.
A sample that is 1.5 inches long, consisting of roughly 200 hair strands (about the diameter of a #2 pencil), taken closest to the scalp, yields 100mg, which is ideal for analysis. For more comprehensive tests like EtG, additional panels, or tests beyond 10 panels, 150mg of specimen is preferred. We advise using a jeweler’s scale to weigh the sample. If scalp hair is not available, an equal quantity of body hair may be used. The term head hair refers specifically to scalp hair, while body hair includes all other types such as facial hair and axillary hair.
Process Overview
The laboratory process for drug testing involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the primary intake of a sample within a laboratory's technology platform. This stage ensures the sample is sealed and transported correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and encompasses any additional tasks not completed by an electronic chain of custody system.
Screening provides a swift preliminary evaluation for illicit substances. While it is a cost-effective strategy to exclude drug use in numerous cases, a positive screen necessitates confirmation before it is allowable in a legal setting. Samples that test presumptively positive during Screening must undergo secondary confirmation.
Upon receiving a positive indication during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are separated from the hair at lower concentrations than other test modalities (e.g., urine or saliva), marking hair drug testing as the toughest methodology to administer.
Positive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS procedures. Prior to confirmation, any presumptively positive samples are cleaned as required. From Accessioning through to Confirmation, the entire laboratory sequence is evaluated under the CAP (College of American Pathologists) Hair criteria and complies with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently labeled as "hair follicle tests", the analysis actually examines the hair strand, 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.
