Accredited Drug Testing offers comprehensive hair follicle drug assessments in Stony Creek, Virginia. If you're in need of a hair or alcohol screening, Accredited Drug Testing excels in hair analysis and has facilities across the nation, capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the crown or body will suffice. These tests can detect drugs, alcohol/ETG, or be tailored for other testing options.
In recent times, hair follicle drug tests have increasingly become the preferred drug testing method. Many workplaces, judicial systems, and Substance Abuse experts require a hair test instead of the usual urine test. Hair follicle screenings are favored by employers with strict no-drug policies, courts, and probationary individuals. The key advantage of a hair follicle test is its extended detection window, capturing drug use for up to 90 days through direct observation, making evasion nearly impossible. Conversely, urine tests remain superior for identifying recent drug use within the past five days.

Hair tests are now recognized as effective means for detecting substance use. Hair encapsulates a lengthy history of alcohol and drug ingestion by embedding biomarkers within its fibers as it grows. When hair is sampled near the scalp, it can offer an approximate three-month window for detecting drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) close to the scalp yields about 100mg of hair, which is the optimal quantity for both screening and validation tests. For EtG, additional tests, and/or assays beyond 10 panels, it is advised to use 150mg of the sample. We suggest measuring the specimen with a jeweler’s scale. If scalp hair isn't obtainable, equivalent body hair can be used. When discussing head hair, we're specifically referring to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test are divided into four steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample undergoes preliminary processing into the lab’s system. This step includes ensuring the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data input that wasn't covered by an electronic chain of custody system.
Screening consists of an initial rapid test for drug presence. Screening is a cost-efficient approach to exclude drug use in most samples; however, for a positive screening to be legally valid, confirmation is necessary. Any samples showing presumptive positive results in Screening are mandated to undergo a secondary confirmation.
If a sample is presumptively positive during Screening, more hair is taken from the original specimen and is readied for Extraction. At this phase, drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.
Positive screening confirmations are performed with GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO/IEC 17025 standards.

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.
