In Beaver Valley, Washington, Accredited Drug Testing offers extensive hair follicle drug testing services. Specializing in hair analysis, our centers perform tests in every city nationwide. Typically, 1.5 to 2 inches of hair from the head or body is required for testing, with options to screen for drugs, alcohol/ETG, or custom-designed parameters.
In recent times, hair follicle drug testing has become a prevalent method for assessing substance use. Employers and judiciary bodies favor it over urine testing due to its zero-tolerance advantage. These tests effectively detect drug use up to 90 days and are significantly more challenging to falsify, though urine tests remain the most accurate for recent substance use within a 5-day period.

Hair analysis has emerged as a remarkable method for identifying the use of drugs and alcohol. Hair gives a prolonged record of alcohol and other drug intake by capturing biomarkers within the fibers of its growing strands. When collected near the scalp, it can present a detection period of up to three months for alcohol and other drugs. Collecting hair is easy, challenging to tamper with, and convenient for shipping.
To procure an ideal sample for analysis and validation, a 1.5-inch segment comprising 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp is needed to produce 100mg of hair. For EtG, supplementary tests, or tests involving more than 10 panels, a specimen weight of 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is absent, a comparable amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair forms (including facial, axillary, etc.).
Process Overview
The processing of a drug test result in a laboratory involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into a lab’s system, where the sample's seal and shipment are validated, a random LAN (Laboratory Accessioning Number) is allocated, and any additional data entry not covered by an electronic chain of custody system is completed.
Screening provides a preliminary examination for drugs of abuse. It is an economical method to exclude drug usage in the majority of cases, although a confirmed screen result is required for it to be permissible in court. Presumptive positive samples from Screening need a subsequent confirmation.
Should a sample be presumptively positive in the Screening phase, further hair is taken from the original sample for Extraction. This phase extracts drugs from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), making hair drug testing the most challenging methodology.
Confirmation for any presumptive positive results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives are washed as necessary. The comprehensive laboratory process from Accessioning to Confirmation is reviewed in accordance with both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Note: Although often referred to as "hair follicle tests", the test itself evaluates the hair strand, not the follicle under 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.
