Accredited Drug Testing offers comprehensive hair follicle drug screening services in Charleston, Oregon. For those in need of hair drug or alcohol assessments, our company specializes in hair analysis, with testing centers available nationwide across all cities. Typically, a hair length of 1.5 to 2 inches from the scalp or body is required. Hair tests can detect drugs, alcohol/ETG, or be customized for specific testing needs.
In recent years, hair follicle drug testing has become more prevalent in the drug screening process. This method is increasingly chosen by employers, courts, and substance abuse professionals over the traditional urine test. Organizations with zero-tolerance drug policies, judicial systems, and probation officers favor hair tests for their extended detection period, which can reach up to 90 days, and observed collection that makes evasion near impossible. Nevertheless, urine tests remain the most accurate choice for detecting substances used within a 5-day timeframe.

The analysis of hair has emerged as a potent method for identifying drug and alcohol usage. Hair captures a long-term history of alcohol and drugs by embedding biomarkers within the fibers of the hair strand as it grows. When hair is collected near the scalp, it offers a detection window of up to around 3 months for both alcohol and drugs. Hair is straightforward to gather, relatively resistant to tampering, and convenient to transport.
A 1.5-inch section of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimum sample amount for both screening and confirmation tests. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair cannot be accessed, a corresponding amount of body hair may be gathered. When we mention head hair, we specifically mean scalp hair only. Body hair includes all other hair variations (facial, axillary, etc.).
Process Overview
The laboratory outcome processing of a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a specimen into a laboratory’s system. This process involves confirming that the sample was properly sealed and shipped, assigning a random Laboratory Accessioning Number (LAN), and completing any additional data entry not conducted by an electronic chain of custody system.
Screening entails an initial rapid evaluation for drug abuse. Although Screening is economical for eliminating drug use in most samples, a positive screen must be confirmed to be permissible in legal contexts. All samples that appear positive during Screening demand secondary verification.
Should a sample appear positive during the Screening phase, additional hair is taken from the original specimen to prepare for Extraction. During this stage, drugs are retrieved from hair at concentrations much lower than those in other methodologies (for example, urine or oral fluid), making hair drug testing the most challenging method to execute.
The confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples presumed positive undergo washing prior to confirmation as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is audited in compliance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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.
