Accredited Drug Testing provides comprehensive hair follicle drug evaluations in Woodbridge, Virginia. For those in need of a hair drug or alcohol assessment, we excel in hair testing and have centers nationwide equipped for this analysis. Generally, 1.5 to 2 inches of hair from the head or body is required. Hair testing can screen for drugs, alcohol/ETG, and other tailored testing needs.
Recently, the preference for drug screening often includes hair follicle analysis. Many employers, judicial bodies, and substance abuse professionals now favor hair tests over urine tests. This method is crucial for zero-tolerance environments, courts, and probation monitoring due to its extended detection period of up to 90 days, conducted under supervision, making it hard to falsify. Yet, for detecting recent drug use within 5 days, urine tests remain the most precise.

Hair examinations are now recognized as a formidable method for uncovering drug and alcohol consumption. Hair encapsulates a history of such substances by securing biomarkers within its fibers as it grows. Collected from near the scalp, hair samples can offer up to a 3-month detection window for alcohol as well as other drugs. Hair collection is straightforward, moderately challenging to tamper with, and easy to transport.
A 1.5-inch specimen consisting of roughly 200 strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the optimal amount for assessments and confirmations. For EtG tests, additional testing, or panels over ten, a 150mg specimen is advised. We propose using a jeweler’s scale for measuring the specimen. When scalp hair is unavailable, a comparable volume of body hair is suitable. By head hair, we mean scalp hair alone. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The chief stages of processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of introducing a sample into the laboratory’s system. This process includes confirming that the sample was sealed and transported correctly, granting a random LAN (Laboratory Accessioning Number), and performing any additional data input absent from an electronic chain of custody system.
Screening involves a preliminary evaluation for drugs of abuse. Although Screening is an economical method for excluding drug use in most samples, a positive result requires confirmation to be valid in a legal context. Any sample that is presumptively positive during Screening necessitates further confirmation.
Should a sample appear presumptively positive in the Screening phase, more hair is extracted from the original sample for Preparation. Extraction retrieves drugs from hair at a lower concentration than other methods (ex. urine or saliva), which renders hair drug testing the most complex methodology.
Confirmatory testing of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing positive are cleansed before confirmation if deemed necessary. The entire lab process from Accessioning to Confirmation undergoes a review aligned with both the CAP (College of American Pathologists) Hair categorization and ISO / IEC 17025 standard 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.
