In Bow, Washington, Accredited Drug Testing provides comprehensive hair follicle drug testing services. Whether you need a drug or alcohol analysis, our expertise in hair testing covers all cities nationwide. Typically, 1.5 to 2 inches of hair from the head's crown or body is sufficient for most tests. Our hair testing options include detection for drugs, alcohol/ETG, or customized analyses.
The hair follicle method has become increasingly favored for drug testing in recent years. Many employers, courts, and substance abuse experts now prefer this over urine tests. Hair tests are adopted by employers with strict drug policies, legal systems, or probation requirements. A significant advantage of hair tests is their extended detection window of up to 90 days, collected through an observed process, making them nearly tamper-proof. However, for detecting recent usage within five days, urine tests remain most effective.

Hair testing is increasingly recognized as an effective means of identifying drug and alcohol use. Hair offers a comprehensive timeline of drug and alcohol consumption by encasing biomarkers within the fibers of growing strands. When extracted close to the scalp, hair can reveal up to a three-month detection period for various substances. It's easy to gather, somewhat resistant to tampering, and simple to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg, the ideal amount for initial and confirmatory testing. For EtG, add-ons, and extensive panels beyond 10, a sample of 150mg is preferred. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can suffice. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The core procedures for processing drug test outcomes in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory system, ensuring it was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry absent from electronic chain of custody systems.
Screening involves a preliminary assessment for drug presence. While it’s a cost-efficient way to dismiss drug presence in most samples, a positive result must undergo confirmation to be valid in legal settings. Samples that are presumptively positive necessitate a subsequent confirmation.
If during Screening, a result is presumptively positive, additional hair from the original sample is readied for Extraction. In this phase, drugs are extracted from hair in significantly lower concentrations than in other methods (such as urine or oral fluid), making hair drug testing one of the most challenging methodologies.
Positive screening outcomes undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleaned before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is critically evaluated under both the CAP (College of American Pathologists) Hair accreditation and adherence to ISO / IEC 17025 standards.

Note: While commonly called "hair follicle tests", this test assesses the hair strand, not 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
