Accredited Drug Testing offers comprehensive hair follicle drug assessments in Phoenix, Oregon. When you require a hair drug or alcohol evaluation, Accredited Drug Testing specializes in hair analysis, and we have facilities in all cities Nationwide ready to conduct such tests. Typically, 1.5 to 2 inches of hair from your crown or body are utilized. Hair evaluations can be conducted for substances, alcohol/ETG, or other specific testing requirements.
In recent years, the approach to substance testing often includes a hair follicle drug examination. Many employers, judicial systems, and Substance Abuse experts are favoring hair tests over standard urine analyses. Hair follicle drug evaluations are employed by organizations adhering to strict drug policies, courts, and probation subjects. The key advantage of hair testing is its extensive detection timeframe, up to 90 days, with an observed collection process that is nearly tamper-proof. For recent substance use detection, within the past 5 days, urine tests remain the most precise.

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair provides an extended record of alcohol and other drug usage by capturing biomarkers within the hair strand's fibers as they grow. When collected near the scalp, hair can reveal up to a 90-day detection window for alcohol and other substances. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (around the diameter of a #2 pencil) proximal to the scalp yields 100mg of hair, the preferred sample size for testing and validation. For EtG, add-ons, and/or tests exceeding 10 panels, a quantity of 150mg is advised. We suggest using a jeweler’s scale for specimen measurement. If scalp hair is not accessible, an equivalent measure of body hair can be used. By head hair, we mean scalp hair only. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Procedure Overview
The four key stages in the lab process of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample within a lab’s framework. This includes verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.
Screening encompasses an initial rapid assessment for drug abuse. Screening provides a cost-effective method to exclude drug usage in most samples, yet a positive result necessitates confirmation for legal admissibility. Samples that are presumptively positive during Screening require an additional confirmation phase.
If a sample tests positive during the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. Here, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), explaining why hair drug screening is the most challenging method to execute.
Confirmation of any positive screening output is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.

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.
