In Foristell, Missouri, Accredited Drug Testing offers comprehensive hair follicle drug testing. Specializing in these tests, we are situated in numerous locations across the nation, ready to handle your needs. Generally, at least 1.5 to 2 inches of hair from the head or body is required for testing. Hair tests can be tailored to detect drugs, alcohol/ETG, among other specifications.
Recently, there's been a growing shift towards using hair follicle drug tests over traditional methods. It's become standard for employers, courts, and Substance Abuse professionals who favor hair testing over urine samples. This is due to the longer detection span—up to 90 days—and rigorous collection methods which make cheating nearly impossible. However, for detecting recent drug use, usually within a 5-day window, urine tests still hold their accuracy.

Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair captures a long-term record of substances by embedding biomarkers within the fibers of the growing hair strand. When obtained near the scalp, hair offers an approximate 3-month detection window for drugs and alcohol. Hair collection is straightforward, less prone to tampering, and convenient for shipping.
For testing, a 1.5-inch sample consisting of about 200 hair strands (comparable in size to a #2 pencil) near the scalp will yield 100mg of hair, the ideal quantity for screening and confirmation. For EtG, extra services, and tests exceeding 10 panels, a 150mg sample is advised. It's beneficial to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair refers to any other types of hair (facial, axillary, etc.).
Process Overview
There are four primary phases in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a lab’s system. This entails confirming the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any outstanding data entry absent from an electronic chain of custody system.
Screening conducts an initial assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in the majority of samples, a positive screen must undergo confirmation to be permissible in court. Samples showing a presumptive positive in Screening necessitate further confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is extracted from the main specimen and set for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), thereby making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

Note: Despite being called "hair follicle tests", the test evaluates the hair strand and not the follicle under the scalp.

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.
