Accredited Drug Testing provides comprehensive hair follicle drug testing services in Knob Noster, Missouri. If you're in need of a hair drug or alcohol assessment, we specialize in hair testing and offer testing centers in various cities across the nation capable of conducting hair tests. Generally, you need 1.5 to 2 inches of hair from the crown or body for analysis. Hair tests can detect drugs, alcohol/ETG, or be customized for specific testing needs.
Recently, hair follicle drug tests have become more prevalent in drug testing procedures. Employers, courts, and Substance Abuse professionals are increasingly opting for hair drug tests over traditional urine tests. Hair follicle drug tests are favored by organizations enforcing zero-tolerance drug policies, court orders, and probation officers. The main advantage is the longer detection window of up to 90 days, collected through an observed procedure, making it nearly impossible to tamper with. However, for detecting drug use within the past 5 days, urine tests remain the most precise.

Hair analysis is recognized as an effective method for uncovering drug and alcohol consumption. With its ability to trap biomarkers in the fibers of a growing hair strand, it offers a prolonged history of substance use. A sample collected from near the scalp can reveal drug and alcohol use over a period of up to 90 days. Hair collection is straightforward, theft-resistant, and conveniently transportable.
An ideal sample for evaluation is a 1.5-inch piece, approximately 200 hair strands, akin to a #2 pencil, nearest to the scalp equaling around 100mg of hair. For tests involving EtG, add-ons, or more than 10 panels, 150mg is advised. Utilize a jeweler’s scale for specimen measurement. If scalp hair is absent, body hair of similar quantity is acceptable. Reference to head hair denotes only scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.
The initial step, Accessioning, involves integrating a sample into a laboratory system, confirming its proper sealing and shipping, assigning it a unique LAN (Laboratory Accessioning Number), and conducting any extra data entry not covered by an electronic chain of custody.
Screening involves a preliminary examination for abusive substances. It serves as a cost-efficient method to exclude drug use for most samples; however, a positive screen requires confirmation for legal validity. Therefore, any positively-screened specimens necessitate secondary verification.
Should a sample test positive during Screening, additional hair is extracted from the initial sample and prepared for the Extraction phase. Here, drugs are extracted at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex method to execute.
For each positive screening result, confirmation is completed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as deemed necessary. The process, right from Accessioning to Confirmation, complies with the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand rather than the follicle itself.

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.
