Accredited Drug Testing offers extensive hair follicle drug assessments in Woodway, Washington. Whether it's a hair drug or alcohol screening you need, Accredited Drug Testing excels in hair analysis with centers across all cities nationwide. Typically, 1.5 to 2 inches of head or body hair is needed. Hair tests accommodate drug, alcohol/ETG, or custom options.
Lately, hair follicle drug testing has become a common method for drug screening. Many companies, courts, and Substance Abuse experts now prefer hair tests over standard urine analysis. Hair tests are favored by employers enforcing strict drug policies, courts, and for individuals on probation. These tests offer a longer detection window of up to 90 days, collected in a supervised manner, making cheating nearly impossible. However, for detecting recent drug use, within 5 days, urine tests remain most effective.

Hair testing is now seen as a formidable method for detecting drug and alcohol consumption. Hair strands offer an extended timeline of alcohol and drug use by encapsulating biomarkers within the fiber of the growing strand. When extracted near the scalp, hair may yield up to nearly a 3-month insight into drug and alcohol use. It is straightforward to procure, relatively resistant to tampering, and convenient for transport.
A sample measuring 1.5 inches of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp provides 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, a specimen of 150mg is advised. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair be inaccessible, an equivalent amount of body hair can be obtained. In our context, head hair denotes only scalp hair. Body hair refers to all other hair categories (including facial, axillary, etc.).
Process Overview
There are four principal stages involved in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of initially registering a sample into the laboratory’s system. It involves confirming that the sample was properly sealed and transported, assigning a random Laboratory Accessioning Number (LAN), and completing any supplementary data entry absent in an electronic chain of custody framework.
Screening entails a preliminary, rapid assessment for drug presence. Although Screening is an economical way to clear most samples of drug use, any positive results must be confirmed to be legally valid. Samples that show preliminary positive results in Screening require an additional confirmation phase.
In instances where a Screening suggests a potential positive outcome, additional hair is taken from the initial sample and readied for Extraction. At this phase, drugs are retrieved from the hair at a notably lower concentration compared to other techniques (e.g., urine or oral fluids), making hair drug screening the most challenging method to execute.
GC/MS, GC/MS/MS, or LC/MS/MS methods are employed for the Confirmation of any positive Screening result. All samples with presumed positive results are cleansed prior to Confirmation when necessary. The comprehensive process from Accessioning to Confirmation is examined under the guidelines of both the CAP (College of American Pathologists) Hair designation and the accreditation standard of ISO/IEC 17025.
Advantages of hair drug testing:
Limitations:
Note: Although called "hair follicle tests", the actual test analyses the hair strand and not the 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.
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.
