Accredited Drug Testing provides thorough hair follicle drug testing services in Kennewick, Washington. Whether you require a hair drug or alcohol test, our expertise lies in hair testing with centers available nationwide to administer your test. Generally, 1.5 to 2 inches of hair from the head or body is sufficient for testing. Hair samples can be tested for drugs, alcohol/ETG, or other specific hair testing needs.
In recent times, hair follicle drug testing has become increasingly prevalent in drug testing protocols. Many employers, the judicial system, and substance abuse specialists are opting for hair drug tests over traditional urine tests. Employers, courts, and individuals on probation utilize hair follicle tests to enforce zero-tolerance policies. A key advantage is its extended detection period, usually up to 90 days, collected under supervision and difficult to alter. Nonetheless, for drug use detection within the past 5 days, urine tests remain the most precise.

Hair testing is increasingly recognized as an effective means to detect drug and alcohol consumption. Hair serves as a chronological record of alcohol and drug intake because it captures biomarkers within the growing hair fibers. When obtained near the scalp, hair can offer a roughly 3-month detection period for alcohol and drugs. It is straightforward to gather, less prone to tampering, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (around the thickness of a #2 pencil) closest to the scalp will produce 100mg of hair, the optimal sample volume for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is advisable. We suggest measuring the specimen with a jeweler's scale. If scalp hair is not accessible, a similar quantity of body hair can be used. When mentioning head hair, it pertains specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage of processing a sample into the laboratory's framework. This phase ensures that the sample was securely sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any data not provided by an electronic custody system.
Screening provides a preliminary check for drugs. While it's an economical way to dismiss drug presence in most samples, a positive result requires confirmation for legal validity. Any presumption of positivity in Screening demands subsequent validation.
Samples indicating potential positivity in Screening entail additional hair extraction for the Extraction phase. Drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair screening a complex technique.
Positive screening findings undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if necessary. The entire procedure, from Accessioning to Confirmation, is rigorously inspected under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", actual analysis focuses on 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 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.
