At Accredited Drug Testing, we offer comprehensive hair follicle drug analysis services in Snoqualmie, Washington. Whether you require testing for drugs or alcohol, we specialize in hair analysis and have testing facilities across all major cities in the nation. Hair from the crown or body, 1.5 to 2 inches in length, can typically be used. Hair tests are designed to detect drugs, alcohol/ETG, or other tailored options.
The trend in recent years for drug screening methods sees an increase in hair follicle testing. Companies, legal entities, and substance abuse experts now often choose hair over urine testing. This method benefits employers with strict drug-free policies and is also used by courts and probationary systems. Its major advantage is the ability to detect drug usage over an extended period of up to 90 days, obtained in an observed setting, making it almost tamper-proof. Nevertheless, for recent drug use within five days, urine tests remain the most precise.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term history of these substances by embedding biomarkers within the fibers of the hair shaft as it grows. When taken near the scalp, hair can offer up to a roughly 3-month timeframe for detecting alcohol and drugs. It is straightforward to gather, relatively hard to tamper with, and easy to send.
A sample of 1.5 inches comprising approximately 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, considered the perfect amount for both screening and confirming results. For EtG, extensions, and/or tests exceeding 10-panel screens, 150mg of hair is advisable. We suggest using a jeweler's scale to measure the sample. If scalp hair isn't available, an equivalent amount of body hair might be used. When we mention head hair, we mean scalp hair exclusively. Body hair includes any other types of hair (facial, axillary, etc.).
Process Overview
There are four primary procedures in the lab processing of a drug test, which include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a specimen into a laboratory's system. This process confirms that the specimen was properly sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and completes any additional information entry not included by an electronic chain of custody protocol.
Screening comprises an initial rapid assessment for substances of abuse. Although Screening is an economically viable method to exclude drug usage in most cases, a positive screen requires confirmation to be valid in legal proceedings. Any samples that return a presumptive positive after Screening necessitate a follow-up confirmation.
If a sample shows a presumptive positive during the Screening phase, further hair is taken from the initial sample and readied for Extraction. This process extracts substances from hair at a much lower concentration compared to other methods (such as urine or oral fluid), hence, hair drug screening is the most challenging process to undertake.
Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if required. The comprehensive lab process, spanning from Accessioning to Confirmation, is reviewed according to the CAP (College of American Pathologists) Hair standards and the ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the test actually examines the hair strand itself and not the hair follicle located 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.
