In McLean, Virginia, Accredited Drug Testing offers comprehensive hair follicle drug testing. Whether you need a screening for drugs or alcohol, our specialized centers, found nationwide, are equipped to conduct these tests. A hair length of 1.5 to 2 inches is generally required, with alternative options available for body hair. These tests provide analysis for various substances, including alcohol/ETG, and can be tailored for specific needs.
Hair follicle drug tests have become increasingly prevalent in recent years. Many employers, judicial systems, and addiction specialists prefer them over traditional urine tests. This method is essential for companies enforcing strict no-drug policies, the legal system, and probation management. The key advantage lies in its extended detection window, up to 90 days, a monitored collection process, and near-immunity to tampering. Urine tests remain most effective for detecting recent drug use, within the past five days.

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of drug and alcohol use by embedding biomarkers within the hair fibers as they grow. When cut near the scalp, hair can yield up to about a three-month detection period for alcohol and drugs. It is easy to gather hair, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch sample comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal sample amount for analysis and validation. In cases of EtG, additional tests, and/or over 10-panel tests, 150mg of hair is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is unavailable, an equivalent quantity of body hair may be collected. When talking about head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (such as beard, underarm, etc.).
Process Overview
The drug testing process in a lab consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is logged into the lab’s system. This step includes confirming that the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any outstanding data input not covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substances of abuse. While Screening is a budget-friendly method to dismiss drug usage in most samples, a positive Screening outcome requires validation to be permissible in legal settings. Any samples that return presumptive positive results during Screening necessitate further confirmation.
If Screening results indicate a potential positive, additional hair is taken from the initial specimen and readied for Extraction. During this stage, drugs are isolated from the hair at a noticeably lower concentration than other testing methodologies (like urine or oral fluid), which accounts for the complexity of performing hair drug screening.
Verification of any positive Screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are potential positives are cleansed before confirmation as needed. The full laboratory process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and in compliance with the ISO / IEC 17025 standards.

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.
