Accredited Drug Testing provides comprehensive hair follicle drug analysis in Raleigh, North Carolina. Specializing in hair drug and alcohol tests, we have testing facilities Nationwide able to conduct hair examinations. Typically, 1.5 to 2 inches of hair from the scalp or body is needed. These tests detect drugs, alcohol/ETG, or can be customized for specific testing needs.
In recent times, drug tests increasingly favor the hair follicle method. Employers, courts, and substance abuse professionals often choose hair tests over urine tests. Organizations with zero-tolerance policies, judicial systems, and probation services rely on hair tests for their extended drug detection capability—up to 90 days. While nearly foolproof, urine remains best for detecting recent drug use within 5 days.

Hair testing has been increasingly recognized as an effective method for identifying drug and alcohol consumption. Unlike other biological samples, hair retains a prolonged historical record by embedding biomarkers within its growing fiber. By taking samples near the scalp, one can get an approximate three-month detection range for alcohol alongside other substances. Hair collection is straightforward, challenging to tamper with, and convenient for shipment.
A sample size of 1.5 inches, consisting of roughly 200 strands (comparable to the diameter of a standard #2 pencil) taken nearest to the scalp, yields 100mg and is considered optimal for testing. For tests such as EtG or those exceeding 10 panels, a 150mg quantity is advisable. A jeweler’s scale is suggested for weighing. If scalp hair isn’t available, the same mass in body hair is suitable. The term head hair specifically means scalp hair, while body hair covers all other types (like facial, axillary, etc.).
Process Overview
The laboratory workflow for drug testing includes four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes its first processing within a laboratory, ensuring it was correctly sealed and shipped, assigning it a unique LAN (Laboratory Accessioning Number), and conducting any required data entries not accounted for by an electronic chain of custody system.
Screening offers a preliminary inspection for substance misuse. While it is a budget-friendly method to eliminate drug use for the majority, any preliminary positive findings require further validation to be court-acceptable. Such presumptive positives necessitate a secondary confirmation.
Presumptive positives from Screening lead to more hair being extracted from the initial sample, gearing up for the Extraction process. Drugs are isolated from the hair at concentrations far lower than other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging.
Upon a positive screen, Confirmation ensues using GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as potentially positive undergo necessary washing prior to confirmation. The complete lab procedure, from Accessioning through to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation.

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.
