Accredited Drug Testing offers comprehensive hair follicle drug testing services in Wilsonville, Oregon. For those requiring drug or alcohol tests, our expertise lies in hair testing, with centers nationwide equipped to conduct such tests. Typically, 1.5 to 2 inches of crown or body hair are necessary. Tests analyze for drugs, alcohol/ETG, or can be customized.
Recently, drug testing methods increasingly feature hair follicle testing. Employers, legal entities, and Substance Abuse experts often prefer hair over urine tests. Especially favored by zero-tolerance employers and legal systems, the tests' main advantage is its extensive detection span of up to 90 days, secured through observed collection, making them highly reliable. However, urine tests remain most precise for usage within the last 5 days.

Hair analysis has emerged as an effective method for identifying substance and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers in the fibers of the developing hair shaft. When sourced near the scalp, hair can offer up to an estimated 3-month window for detecting alcohol and other substances. Hair is straightforward to collect, relatively hard to tamper with, and easy to deliver.
A 1.5-inch section consisting of around 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for analysis and verification. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg of the specimen is advised. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be gathered. When mentioning head hair, we reference only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Summary
The four primary steps in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a specimen within a laboratory’s system. This involves checking that the specimen was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not supplied by an electronic chain of custody system.
Screening includes an initial swift assessment for substances of misuse. While Screening is a cost-effective approach to exclude substance usage in most samples, a positive result requires confirmation to be valid in court. Any samples that are provisionally positive in Screening necessitate a secondary verification.
If a sample is provisionally positive in the Screening phase, more hair is extracted from the initial specimen and prepared for Extraction. During this phase, substances are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug analysis is the most challenging method to execute.
Verification of any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to verification if necessary. The full laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
