Accredited Drug Testing offers comprehensive hair follicle drug assessments in Eldon, Washington. If you require a hair or alcohol analysis, Accredited Drug Testing excels in these assessments, with centers available Nationwide. Typically, 1.5 to 2 inches of hair from the crown or body is needed. These tests can gauge drugs, alcohol/ETG, or other tailored hair testing options.
In recent years, hair follicle drug testing has become increasingly commonplace. Employers, judicial systems, and substance abuse experts now often prefer it over urine testing. This method is favored by firms with strict no-drug policies, courts, and those overseeing probation. The main advantage is a longer detection window, generally up to 90 days, conducted under supervision, rendering it nearly tamper-proof. However, for recent drug use detection within a 5-day timeframe, urine testing remains the benchmark.

Hair diagnostics have evolved into a robust method for uncovering substance and alcohol consumption. Hair archives a prolonged history of intoxicants by capturing biomarkers within its growing fibers. When harvested near the scalp, it offers an approximate 3-month detection timeline for alcohol and drugs. Collection is straightforward, challenging to tamper with, and simple to transport.
An inch and a half segment of around 200 hair strands (resembling a #2 pencil's girth) nearest to the scalp provides 100mg of hair, the optimal unit for analysis and verification. For EtG, additional tests, and/or over 10-panel tests, a 150mg sample is advised. It's recommended to weigh the sample on a jeweler’s scale. If scalp hair isn't present, an equivalent quantity of body hair is an option. When mentioning head hair, it specifically implies scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The lab processing of a drug test encompasses four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is logged into the lab system. This verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes extra data entry absent from the electronic chain of custody system.
Screening entails a preliminary assessment for drug abuse indicators. While Screening is a budget-friendly approach to eliminate drug usage in most cases, a positive result must be confirmed for legal admissibility. Any samples that test positive in Screening require subsequent confirmation.
If the Screening phase yields a positive result, additional hair is extracted from the initial sample and prepped for Extraction. Here, drugs are isolated from hair at much lesser concentrations than other methods (e.g., urine or oral fluid), explaining why hair drug evaluation is the most complex to conduct.
Positive screening outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. All samples suggesting a positive result undergo washing before confirmation as required. The full lab procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair classification and the ISO/IEC 17025 standard accreditation.

Note: Frequently termed as "hair follicle tests", the process analyzes the hair strand rather than 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.
