Accredited Drug Testing provides comprehensive hair follicle drug assessments in Kent, Washington. At Accredited Drug Testing, we specialize in hair testing, with centers in cities nationwide that can conduct a hair test if you require a drug or alcohol analysis. Typically, 1.5 to 2 inches of hair from the crown or body is needed. Hair tests detect drugs, alcohol/ETG, or can be tailored to other needs.
Recently, the preference for drug testing methods has increasingly shifted towards hair follicle assessments. Employers, courts, and Substance Abuse specialists often prefer this over standard urine testing. Hair drug tests support zero-tolerance policies and are essential for courts and those on probation. The key advantage lies in its extended detection timeframe of up to 90 days, observed collection process, and minimal chance of tampering. However, for recent drug use within 5 days, urine tests remain most accurate.

Hair examinations are now recognized as a robust method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug usage by capturing biomarkers in the fibers of the hair as it grows. When hair is cut near the scalp, it can provide an approximate 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and easy to send.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (equal to the size of a #2 pencil), located closest to the scalp, provides 100mg, the optimal quantity for analysis and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to measure specimen weight. If scalp hair is absent, a comparable amount of body hair can be gathered. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The primary phases in the laboratory evaluation of a drug test are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into a lab’s system. This includes confirming that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not covered by an electronic chain of custody.
Screening is a preliminary quick test for drug abuse. Though Screening is cost-effective for excluding drug use in numerous samples, a positive outcome requires confirmation for use in legal settings. Any samples that test presumptively positive during Screening necessitate additional confirmation.
When a sample tests presumptively positive in Screening, more hair is taken from the original specimen and readied for Extraction. In this phase, drugs are isolated from hair at a much lower concentration than other methods (e.g., urine or oral fluid), making hair drug testing one of the most intricate methods to conduct.
Verification of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if needed. The entire lab process, from Accessioning to Confirmation, is inspected under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Note: Despite often being named "hair follicle tests," the analysis targets the hair strand rather than the hair follicle beneath the scalp.

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.
