Accredited Drug Testing provides comprehensive hair follicle drug testing in Gladstone, Virginia. For those requiring a hair drug or alcohol test, we specialize in hair testing and offer test centers across all Nationwide cities capable of conducting a hair test. Typically, 1.5 to 2 inches of hair from the head or body is needed. Hair tests can examine drugs, alcohol/ETG, or other custom options.
Recently, hair follicle drug testing has become a more common method in drug test procedures. Many employers, legal systems, and substance abuse experts now opt for a hair drug test over a urine test. Hair follicle drug tests appeal to employers with zero-drug tolerance policies, legal entities, and those on probation due to their longer detection period, typically up to 90 days, collected through observed methods, and being nearly impossible to falsify. However, urine tests remain the most precise for identifying drug use within the last 5 days.

Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and other substances by capturing biomarkers within the fibers of the growing strand. When collected near the scalp, it offers approximately a 3-month detection window for alcohol and other drugs. Hair samples are easy to gather, comparatively hard to tamper with, and convenient to ship.
A 1.5-inch sample with around 200 hair strands (about the diameter of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional analyzes, and/or tests over 10 panels, 150mg of the specimen is advised. It is advisable to weigh the specimen using a small scale. If scalp hair is not present, an equivalent volume of body hair can be used. 'Head hair' specifically denotes scalp hair, while 'body hair' encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory drug test result processing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step in processing a sample within a lab’s framework. This phase ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data input not managed by an electronic chain of custody system.
Screening includes a preliminary evaluation to spot drugs of abuse. While Screening effectively determines drug use in most samples, a positive result requires confirmation for legal admissibility. Any samples that yield presumptive positives during Screening must undergo secondary confirmation.
If a sample is presumptively positive at the Screening stage, additional hair is extracted from the main specimen and readied for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to carry out.
Confirmation of any screening positive is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The full laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation in addition to ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly known as "hair follicle tests", the test actually evaluates the hair strand rather than the follicle beneath the scalp.

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.
