In Lake Saint Louis, Missouri, Accredited Drug Testing provides extensive hair follicle drug testing services. Specializing in both hair drug and alcohol tests, they have facilities throughout the nation. Having 1.5 to 2 inches of hair on your head or other body parts is generally sufficient. Hair tests can analyze drugs, alcohol/ETG, and other customized options.
Hair follicle drug tests have increasingly become the preferred method for drug testing in recent years. They're used by employers with strict no-drug policies, courts, and rehabilitation professionals who choose this method over traditional urine tests. A key advantage of hair testing is its extended detection period of up to 90 days, conducted in a supervised setting, making it highly tamper-resistant. However, urine testing remains most reliable for detecting recent use within five days.

Hair testing has emerged as a potent resource for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drugs by preserving biomarkers within the fibers of the growing strand. When procured near the scalp, hair can offer roughly up to a 3-month detection timeframe for alcohol and other drugs. It is easy to collect, somewhat resistant to tampering, and simple to ship.
A 1.5-inch section consisting of roughly 200 hair strands (resembling the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for analysis and verification. For EtG, add-ons, and/or testing beyond 10 panels, 150mg of the sample is advisable. We suggest using a jeweler's scale for weighing the sample. If head hair is not available, an equivalent quantity of body hair can be collected. When we mention head hair, it specifically refers to scalp hair. Body hair includes all other hair types (facial, underarm, etc.).
Process Overview
The four principal stages in the laboratory handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab’s system. This incorporates confirming that the sample was correctly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finishing any additional data entry not already provided by an electronic chain of custody system.
Screening comprises an initial rapid evaluation for drugs of misuse. Although Screening is a cost-efficient approach to dismiss drug usage in most samples, a positive screening must be validated to be acceptable in court. Samples that are presumptively positive during Screening need secondary confirmation.
Should a sample read presumptive positive at the Screening stage, more hair is extracted from the initial specimen and readied for Extraction. At this phase, drugs are withdrawn from hair at a notably lesser concentration than in alternative methodologies (such as urine or oral fluid), which is part of why hair drug screening is the most complex methodology to conduct.
Verification of any positive screening result is executed via GC/MS, GC/MS/MS or LC/MS/MS. Every presumptive positive sample receives a wash before verification as necessary. From Accessioning to Confirmation, the entire laboratory process is scrutinized under the CAP (College of American Pathologists) Hair designation as well as accreditation to ISO / IEC 17025 standards.

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.
