Accredited Drug Testing offers thorough hair follicle drug assessments in Medical Lake, Washington. If a hair drug or alcohol screening is necessary, Accredited Drug Testing specializes in hair testing with facilities across all cities Nationwide. Generally, 1.5 to 2 inches of hair from the crown or body hair is required. Hair assessments can detect drugs, alcohol/ETG, or other customized testing solutions.
In recent years, drug testing methods have increasingly utilized hair follicle drug tests. More employers, courts, and Substance Abuse experts now favor hair tests over standard urine tests. Zero-tolerance employers, courts, and those on probation rely on hair testing; its key advantage is a much longer detection window, typically up to 90 days, collected under observation, making tampering nearly impossible. However, for substance use detection within the last 5 days, urine tests remain most precise.

Hair analysis is recognized as an effective method for spotting drug and alcohol consumption. Hair retains a prolonged record of alcohol and drugs by encapsulating biomarkers within the developing hair strands. When sampled near the scalp, hair can show a detection timeframe of approximately 3 months for both alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches, comprising about 200 hairs (roughly the width of a #2 pencil), nearest the scalp yields 100mg, the optimal amount for screening and verification. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair is not present, an equivalent quantity of body hair can be gathered. The term 'head hair' specifically denotes scalp hair, while 'body hair' indicates all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results follows four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the initial sample processing in the laboratory system. This step includes ensuring the sample's seal and correct shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry if not already covered by an electronic chain of custody procedure.
Screening acts as an initial cursory review for drugs of abuse. While Screening is a budget-friendly method to exclude drug usage in most samples, any positive screen requires confirmation for legal admissibility. Samples that are tentatively positive in Screening need secondary confirmation.
When Screening suggests a positive result, additional hair is taken from the original sample for Extraction. At this phase, drug extraction from hair is at a lower concentration than through other methods (e.g., urine or saliva), signifying the high complexity of hair drug screening.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if necessary. The complete laboratory protocol, spanning from Accessioning through to Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair criteria and the accreditation according to ISO / IEC 17025 standards.

Note: Despite the common term "hair follicle tests", the analysis actually evaluates the hair strand rather than the 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.
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.
