Accredited Drug Testing offers comprehensive hair follicle drug testing solutions in Alderdale, Washington. If your requirements include a hair drug or alcohol test, Accredited Drug Testing stands ready with expertise in hair analysis, providing testing facilities in all cities across the nation capable of conducting such tests. Typically, 1.5 to 2 inches of hair from your scalp or body can be used for these assessments. Hair analyses can detect substances like drugs, alcohol/ETG, or be tailored to other testing needs.
Over the years, hair follicle testing has increasingly replaced traditional drug testing methods. More employers, judicial systems, and Substance Abuse experts now favor hair tests over typical urine tests. Hair follicle tests are preferred by employers with strict no-drug policies, legal courts, and probation officers. The chief advantage of these tests is their ability to detect drug use over a longer duration, typically up to 90 days, through an observed sample collection, which makes tampering highly improbable. Nonetheless, recent drug use within a five-day window is best detected by urine tests.

Hair analysis is increasingly recognized as a significant method for identifying drug and alcohol consumption. Hair captures long-term alcohol and drug data by encasing biomarkers within the hair fiber's structure. When harvested from the scalp's proximity, hair allows for nearly a 3-month drug and alcohol detection period. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch hair sample consisting of roughly 200 strands (comparable to the width of a #2 pencil) nearest the scalp yields 100mg, the preferred amount for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen amounting to 150mg is advisable. We suggest weighing the sample with a jeweler’s scale. Should scalp hair be unobtainable, a similar quantity of body hair can be gathered. "Head hair" refers solely to scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).
Process Overview
The lab processing of a drug test involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample within a lab system. This step includes confirming the sample's proper sealing and shipment, issuing a LAN (Laboratory Accessioning Number), and completing additional data entry omitted by an electronic chain of custody tool.
Screening conducts a preliminary assessment for substance abuse. Though cost-effective in excluding drug use from the majority of samples, any positive screens must undergo confirmation for court admissibility. Samples showing presumptive positives during Screening necessitate further confirmation.
Upon a presumptive positive result in Screening, additional hair is extracted from the original sample and readied for Extraction. During Extraction, drugs are isolated from hair at lower concentrations than in other testing methods (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.
Positive results from Screening are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are washed as needed before confirmation. The entire processing cycle from Accessioning to Confirmation undergoes review per the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: While often referred to as "hair follicle tests", the analysis focuses on the hair strand rather than the 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
