Accredited Drug Testing in Duvall, Washington offers comprehensive hair follicle drug analysis services. Specializing in hair tests, we have nationwide centers equipped for this procedure. Typically, 1.5 to 2 inches of crown or body hair is required. Hair can be screened for substances like drugs or alcohol, with customizable test options available.
In recent years, hair follicle testing has become more popular in drug screening processes. This test is frequently requested by employers, legal systems, and Substance Abuse experts, preferring it over urine tests. Entities with strict drug policies, like employers and courts, often choose hair tests due to their 90-day detection capability, providing a nearly tamper-proof method. Nevertheless, for recent drug use within 5 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 increasingly recognized as a formidable method for detecting drug and alcohol usage. Hair acts as a repository of long-term consumption data by embedding biomarkers within the fibers as the hair grows. When samples are taken near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and drugs. The process of collecting hair is straightforward, less susceptible to tampering, and convenient to transport.
A sample measuring 1.5 inches and consisting of about 200 hair strands (comparable to a #2 pencil) closest to the scalp will yield 100mg, an optimal amount for screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, it is advisable to collect 150mg of the sample. We suggest measuring the sample on a jeweler's scale. In the absence of scalp hair, an equivalent volume of body hair is permissible. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
There are four principal steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a lab's system. This step includes confirming the sample's proper sealing and shipping, allocating a randomized LAN (Laboratory Accessioning Number), and filling in any missing data not provided by an electronic chain of custody system.
Screening serves as an initial rapid assessment for abused drugs. Though Screening is a budget-friendly approach to exclude drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Samples that show a possibly positive result in Screening require an additional confirmation step.
Should a sample demonstrate a presumptively positive response during Screening, more hair is drawn from the original sample and prepared for Extraction. In Extraction, drugs are isolated from hair at concentrations much lower than seen in other approaches (e.g., urine or oral fluid), thus making hair drug screening the most intricate method to execute.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are cleansed before confirmation as needed. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.
