Accredited Drug Testing offers comprehensive hair follicle drug analyses in Sequim, Washington. Whether you need drug or alcohol testing, Accredited Drug Testing excels in hair analyses and has centers across the nation. Generally, 1.5 to 2 inches of hair from the scalp or body is required. Hair tests can screen for various substances including drugs and alcohol/ETG.
Hair follicle drug tests have increasingly been chosen over urine tests for substance screening. Both employers, judicials, and Substance Abuse experts often prefer them. These tests are favored by employers with zero-tolerance drug policies, courts, and probation officers due to their longer detection window, typically extending up to 90 days, and because they are hard to tamper with. However, urine tests remain more precise for identifying recent drug use within the last 5 days.

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.
Seen as a robust means for assessing use of substances, hair testing captures long-term data by preserving biomarkers within hair fibers. Hair near the scalp offers a detection window of up to 3 months for alcohol and other drugs. It is convenient to collect, hard to tamper with, and easy to transport.
A sample measuring 1.5 inches and consisting of around 200 strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-ons, and tests above 10 panels, it is best to have 150mg of the specimen. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent quantity of body hair can be used. By head hair, we mean only scalp hair, while body hair covers all other types (facial, axillary, etc.).
Process Overview
The key phases in lab processing of a test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This step checks that the sample was correctly sealed and shipped, assigns a LAN (Laboratory Accessioning Number), and finishes any extra data entry not covered by an electronic chain of custody system.
Screening serves as a preliminary test for drug abuse. Though it is a cost-efficient way to exclude drug usage for most samples, a positive result from this requires confirmation for legal admissibility. All samples deemed presumptively positive in Screening require a secondary confirmation.
When a sample is potentially positive in Screening, extra hair from the original sample is prepared for Extraction. Drugs are isolated from hair at lower concentrations compared to other methods (ex. urine or oral fluid), contributing to the complexity of hair drug screening.
Confirmation occurs through GC/MS, GC/MS/MS, or LC/MS/MS for any positive screening. Before confirmation, all presumptive positive samples are cleaned as necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.

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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
