Accredited Drug Testing provides comprehensive hair follicle drug screening in Emporia, Virginia. If a hair drug or alcohol test is required, Accredited Drug Testing specializes in this area and offers testing centers in cities across the Nation where such tests can be conducted. Approximately 1.5 to 2 inches of hair on the head or body is required. Hair tests can detect drugs, alcohol/ETG, or other specific substances.
Drug testing methods have recently leaned more towards hair follicle drug tests. Many employers, judicial systems, and Substance Abuse experts now prefer hair drug tests over traditional urine tests. Hair follicle testing is chosen by organizations with stringent drug policies, courts, and probation services. It offers an extended detection window, lasting up to 90 days, is collected under supervision, and is notoriously hard to deceive. However, urine tests remain the most precise for detecting very recent drug use within the past five days.

The perception of hair testing as an effective method for detecting drug and alcohol consumption has grown. Hair allows for a prolonged overview of substance use by embedding biomarkers within its evolving fibers. When hair is harvested near the scalp, it can reveal up to a three-month timeline for drug and alcohol presence. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
For optimal analysis and verification, a 1.5-inch segment comprised of roughly 200 hair strands (comparable to a #2 pencil) near the scalp can yield 100mg, which is deemed ideal. However, for EtG, additional substances, or tests exceeding ten panels, a sample of 150mg is advised. It's best to measure the sample using a precision jeweler’s scale. If scalp hair is not an option, a similar amount of body hair can be used. All references to head hair specifically pertain to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially logged into the lab's system. This step ensures the sample is properly sealed and delivered, assigns an arbitrary LAN (Laboratory Accessioning Number), and inputs any additional data not covered by an electronic custody chain.
Screening performs an initial, rapid assessment for drug presence. As a cost-efficient method, it can often rule out substance use in most samples; however, to be legally valid, a positive Screen requires confirmation. Any samples indicated as positive during Screening need a follow-up confirmation test.
If Screening suggests a positive, more hair from the initial sample is set aside for Extraction. In this step, drug compounds are extracted from the hair at a dramatically reduced concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analyses.
For Confirmation, any suspect positive outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing positive are cleansed before Confirmation as necessary. The entire flow from Accessioning to Confirmation is vetted under the CAP (College of American Pathologists) Hair designation and aligned with ISO / IEC 17025 accreditation.

Note: Despite often being named "hair follicle tests," the evaluation targets the hair strand 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.
