Based in Cary, North Carolina, Accredited Drug Testing offers comprehensive hair follicle drug testing. Whether it's for drugs or alcohol, our specialized hair testing services are available in locations across all cities nationwide. Typically, 1.5 to 2 inches of hair from the crown of your head or body can be used. These tests can detect drugs, alcohol/ETG, or be tailored for other specific substances.
The popularity of hair follicle drug tests has risen among methods utilized for drug testing. A growing number of employers, courts, and Substance Abuse professionals now demand a hair drug test rather than standard urine testing. Hair follicle tests are preferred by companies with zero-tolerance drug policies and for individuals on probation. Their advantage includes an extended detection time, up to 90 days, collected through an observed process, and are almost immune to tampering. However, for detecting recent drug use within the past 5 days, urine tests remain the most accurate.

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. It provides a comprehensive history by embedding biomarkers in the fibers as the hair grows. When samples are collected near the scalp, they can reveal alcohol and drug traces for up to about a 3-month period. Hair is easy to gather, not easily tampered with, and convenient to transport.
For screening and verification, a 1.5-inch section with around 200 hair strands (approximately the thickness of a #2 pencil) next to the scalp is required to obtain 100mg, which is the preferred quantity. For EtG, supplementary checks, and/or analyses above 10 panels, 150mg of the sample is advised. Using a jeweler's scale to measure the specimen is advisable. If head hair is unattainable, an equivalent amount of body hair is acceptable. When discussing head hair, it strictly refers to scalp hair. Body hair includes all other types such as facial and axillary.
Process Overview
The testing procedure in a laboratory consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample is first processed into the lab's system. This phase includes checking that the sample was correctly sealed and dispatched, assigning it a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody.
Screening acts as an initial evaluation for substances of abuse. While it serves as an economical strategy to eliminate drug use in most samples, a positive result requires confirmation for legal acceptability. Any samples indicating prescriptive positive results during Screening need verification.
When screening suggests a positive result, additional hair is taken from the original sample for Extraction. During Extraction, drugs are isolated from the hair at a significantly lower concentration relative to other forms like urine or oral fluid, posing a higher complexity in hair drug tests.
Drug screen results that indicate a positive outcome are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples go through a washing stage before confirmation as needed. The complete lab workflow from Accessioning to Confirmation is monitored under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 certification standards.

Note: Despite often being termed "hair follicle tests," the procedure examines the hair shaft and 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.
