Accredited Drug Testing offers comprehensive hair follicle drug testing services in Stevenson, Washington. For those needing a hair-based drug or alcohol screening, Accredited Drug Testing excels in hair testing and provides facilities nationwide to conduct these tests. Typically, a 1.5 to 2-inch hair sample from the crown or body is required. These tests are capable of detecting drugs, alcohol/ETG, and can be tailored to specific testing needs.
Over the past few years, drug testing procedures increasingly favor hair follicle drug tests. Employers, judicial systems, and substance abuse professionals often mandate these tests over standard urine screenings. Hair follicle testing is popular among zero-tolerance policymakers, courts, and probation officers due to its extended detection timeframe of up to 90 days and an observed collection process that is difficult to tamper with. However, for detecting recent drug use within five days, urine tests remain the most precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the hair strand fibers. When sourced near the scalp, hair can offer an approximate 3-month detection timeframe for alcohol and drugs. Hair is easy to collect, challenging to alter, and simple to transport.
A 1.5-inch hair sample, consisting of about 200 strands (comparable to the width of a #2 pencil) near the scalp, yields 100mg of hair, which is the perfect quantity for analysis and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. Using a jeweler’s scale is recommended for weighing the specimen. If scalp hair isn’t available, a comparable quantity of body hair is acceptable. References to head hair indicate scalp hair exclusively. Body hair encompasses all other types, such as facial and axillary hair.
Process Overview
Lab processing of a drug test consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into the laboratory's system. It involves checking that the sample was properly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and inputting any missing data not provided by an electronic chain of custody system.
Screening is a preliminary inspection for drug abuse. Although Screening is an economical way to dismiss drug use in most samples, positive results require confirmation to be valid in legal proceedings. Samples that show a presumptive positive in Screening need further confirmation.
When a sample tests presumptively positive during the Screening phase, more hair is obtained from the primary sample and processed for Extraction. In extraction, drugs are separated from hair at lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug testing the most intricate to perform.
Confirmation of any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are pre-washed before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Note: Despite the common term "hair follicle tests", the procedure examines the hair strand, not the follicle beneath the scalp.

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.
