Accredited Drug Testing offers comprehensive hair follicle drug assessments in McMinnville, Oregon. If a hair or alcohol test is required, our company focuses on hair evaluations, with numerous facilities across every city nationally to conduct the test. Ideally, 1.5 to 2 inches of hair from the crown or body is necessary. Hair analysis can detect drugs, alcohol/ETG, or custom test options.
Lately, hair follicle drug evaluations have become a preferred method for substance testing. Multiple employers, legal institutions, and Substance Abuse experts favor hair analysis over traditional urine methods. This choice is popular among employers with strict no-drug policies, justice systems, and individuals on probation. The main advantage is its prolonged detection period, usually up to 90 days, through a direct observation, proving hard to manipulate. Yet, for usage within the previous 5 days, urine tests remain most precise.

Currently, hair testing is regarded as an effective instrument for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers as they develop, offering an extended historical record of alcohol and drug intake. When procured near the scalp, hair can reveal substance use over roughly a three-month period. It is straightforward to collect, challenging to tamper with, and convenient to transport.
Collecting a 1.5-inch segment of around 200 hair strands (about the size of a #2 pencil) near the scalp produces 100mg, which is ideal for conducting screenings and confirmations. For materials like EtG, supplementary measures, and tests exceeding 10 panels, a quantity of 150mg is advisable. We suggest measuring the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a similar amount of body hair can be used instead. "Head hair" specifically pertains to hair from the scalp. In contrast, "body hair" refers to other types (e.g., facial, axillary).
Process Overview
The laboratory analysis of a drug testing result consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial input of a sample into a laboratory's records. This process involves verifying the sample's proper sealing and transportation, creating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not provided via an electronic custody protocol.
Screening represents the initial, swift inspection for drugs of abuse. While Screening offers a cost-efficient means to dismiss drug use across the majority of samples, a positive screen must be authenticated for court acceptance. Samples yielding presumptively positive results in Screening necessitate secondary confirmation.
For any samples deemed presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are removed from hair in concentrations notably lower than those found through other methods (e.g., urine or oral fluid), making hair drug testing among the most complex methodologies.
Confirmation of any positive results from Screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. Should it be necessary, all presumptively positive samples undergo washing prior to confirmation. This entire laboratory procedure, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests," the examination actually assesses 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
