Accredited Drug Testing offers comprehensive hair follicle drug testing services in Competition, Missouri. Specializing in this type of testing, we cater to those needing a hair drug or alcohol test, with facilities in cities across the nation. Typically, hair lengths of 1.5 to 2 inches from the crown or body are suitable. Our hair tests target drugs, alcohol/ETG, or can be designed to meet specific needs.
Recently, the preference for conducting drug tests has shifted towards hair follicle techniques. Employers, legal systems, and substance abuse experts often favor hair drug testing over urine analysis. Hair tests are ideal for entities with zero-tolerance drug use policies or for monitoring probation conditions. Their main advantage is a longer detection window of up to 90 days, secure observed collections, and a design that minimizes the chances of tampering. However, for detecting recent use within five days, urine remains the more precise test.

Hair testing is increasingly viewed as a potent method for detecting drug or alcohol usage. Hair strands trap biomarkers in their fibers, providing a long-term record of alcohol and drug use. When gathered near the scalp, hair can offer a detection period of up to 3 months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
A 1.5-inch sample comprising about 200 hair strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg, which is the ideal sample size for both screening and confirmation processes. For EtG, additional tests, or tests exceeding 10 panels, a specimen size of 150mg is advisable. It's recommended to measure the specimen on a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected. When discussing head hair, it pertains solely to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into the lab’s system, ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any data entries the electronic chain of custody system might lack.
Screening is an initial rapid assessment for drugs of abuse. While it is a cost-efficient method to rule out drug use in most samples, a positive screen needs confirmation for legal admissibility. Presumptively positive samples in Screening require a secondary confirmation.
If Screening suggests a sample is positive, additional hair is extracted from the original specimen for the Extraction process. This involves extracting drugs from hair at significantly lower concentrations as compared to methods like urine or oral fluid, which renders hair drug analysis a tricky methodology.
Confirmation of any positive screen result is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all presumptively positive samples undergo washing as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:

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.

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.
