Accredited Drug Testing provides comprehensive hair follicle drug testing in Chehalis Village, Washington. Whether you require a hair test for drugs or alcohol, Accredited Drug Testing offers specialized hair testing services. With testing centers in every city nationwide, we can conduct hair tests efficiently. Generally, 1.5 to 2 inches of hair from your head or body hair is needed. Hair tests can be customized for drug, alcohol/ETG, or other analyses.
In the past few years, the approach to drug testing increasingly favors hair follicle drug tests. Various employers, courts, and Substance Abuse experts now demand a hair drug test over the standard urine test. These tests are valued by employers with zero-tolerance drug policies, courts, and probation officers. The significant advantage of hair follicle tests is the extended detection period for drug use, typically up to 90 days, acquired through observed collection, making it nearly impossible to manipulate. However, for detecting drug use in the past five days, urine tests remain highly accurate.

Hair analysis is recognized as a significant method for identifying substance and alcohol consumption. Hair encases historical data on both alcohol and drugs by embedding biomarkers within the strands. Obtaining hair samples near the scalp allows for a detection timeframe of up to roughly three months for substances. The process of collecting hair is straightforward, it resists tampering, and shipping is uncomplicated.
A sample measuring 1.5 inches and containing around 200 hair strands (comparable to a #2 pencil's thickness) from near the scalp yields 100mg, the ideal quantity for testing. For EtG, additional tests, or those beyond 10 panels, a 150mg sample is advisable. We suggest using a jeweler's scale for measuring. If scalp hair is absent, collecting an equivalent bulk of body hair suffices. "Head hair" denotes scalp strands; in contrast, "body hair" encompasses facial, axillary, and other types.
Process Overview
The sequence of steps in lab processing for a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning introduces the sample into a lab's system. This phase checks the sample's proper sealing and shipping, assigns a LAN (Laboratory Accessioning Number), and finalizes any pending data entry not captured by an electronic chain of custody system.
Screening provides an initial, rapid assessment for drugs. While cost-efficient for eliminating drug use in most samples, a positive screening requires confirmation for legal acceptance. All presumed positive results during Screening need further validation.
When a presumed positive arises from Screening, additional hair is collected from the primary sample for Extraction. In this phase, substances are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluids), increasing the complexity of hair drug testing.
Confirmation of any positive screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumed positives are washed if necessary. Each lab process, from Accessioning to Confirmation, undergoes review by CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the evaluation targets the hair strand, not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
