In Webster Groves, Missouri, Accredited Drug Testing offers thorough hair follicle drug analysis. Whether seeking a test for drugs or alcohol, our centers nationwide can assist with hair-based assessments. Typically, a hair length of 1.5 to 2 inches is required, though body hair may suffice. Our tests can detect various substances like drugs, alcohol/ETG, or cater to specific testing needs.
The rise in popularity of hair follicle drug testing has been notable among employers, courts, and Substance Abuse experts who prefer it over standard urine methods. Employers with strict no-drug policies, judicial systems, and probation officers often choose hair testing. Its key advantage is a 90-day detection window, making tampering nearly impossible. Conversely, urine tests remain more reliable for recent use, up to five days.

Hair analysis has evolved into a robust method for identifying drug and alcohol consumption. Hair strands capture and retain biomarkers within their fibers, offering a prolonged history of substance use. When the hair is harvested near the scalp, it can provide an approximate 3-month detection span for both alcohol and drugs. It's straightforward to gather, relatively resistant to tampering, and convenient to transport.
A segment measuring 1.5 inches, composed of roughly 200 hair strands (comparable to a #2 pencil's width) near the scalp, yields 100mg of hair, which is an optimal sample for both screening and confirmatory purposes. For EtG, additional tests, or those exceeding 10 panels, a 150mg specimen is advised. It's suggested to weigh the hair using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be taken. References to head hair pertain exclusively to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes integrating a sample into a lab's system initially. This step involves confirming that the sample is correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data tasks absent from an electronic chain of custody system.
Screening consists of a preliminary rapid check for substances of abuse. Although Screening is a cost-efficient means to dismiss drug usage for most samples, a positive outcome requires confirmation for legal admissibility. Samples that are presumptively positive in Screening necessitate secondary validation.
Presumptive positives in the Screening phase require more hair from the initial collection for preparation in the Extraction phase. During this phase, drug compounds are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis compared to other testing methodologies.
In the Confirmation phase, any positive screening outcomes are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed pre-confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation adheres to standards from both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

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.
