Accredited Drug Testing offers comprehensive hair follicle tests in Leesburg, Virginia. For anyone requiring hair drug or alcohol assessments, our expertise lies in hair testing, with facilities available nationwide, ready to conduct these tests. Ideally, individuals should have 1.5 to 2 inches of hair on the scalp, though body hair is also typically suitable. These tests can detect drugs, alcohol/ETG, or be customized for other specific inquiries.
Recently, hair follicle drug testing has seen an uptick in application alongside standard drug testing methods. Businesses, judicial entities, and substance abuse authorities increasingly opt for hair-based tests over traditional urine analyses. Employers, particularly those with zero-tolerance policies, benefit from the hair test’s extended detection window of approximately 90 days, its observed collection process, and the difficulty in falsifying results.

Hair testing is regarded as a robust method for identifying drug and alcohol consumption. It offers a prolonged record of these substances by retaining biomarkers within the fibers of growing hair strands. When collected near the scalp, hair facilitates an approximate 3-month detection timeframe for alcohol and drugs. It is easy to gather, somewhat resistant to tampering, and straightforward to transport.
A 1.5-inch sample with around 200 hair strands (similar in size to a #2 pencil) nearest the scalp provides 100mg of hair, an ideal quantity for thorough examination and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg is advised. We suggest measuring the sample with a jeweler’s scale. Should scalp hair be inaccessible, an equivalent amount of body hair can be used instead. When discussing head hair, scalp hair is implied exclusively. Body hair signifies all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory treatment of a drug test result encompasses four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary treatment of a sample within a laboratory’s framework. This phase ensures the proper sealing and dispatch of the sample, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplemental data entry absent from an electronic chain of custody system.
Screening offers a preliminary review for substances of abuse. Screening serves as a budget-friendly manner to exclude drug consumption across most samples; however, a positive finding necessitates confirmation to uphold it in court. Samples yielding a presumptive positive in Screening mandate a secondary validation.
In the event a sample exhibits a presumptive positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. Here, drugs are removed from the hair at much reduced concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to execute.
Confirmation of any positive outcome post-screening is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples undergo washing before confirmation as needed. The whole laboratory cycle, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 standards accreditation.

Limitations:
Note: Frequently termed "hair follicle tests," the examination analyzes the hair strand itself, rather than the hair follicle beneath the scalp.

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.
