Accredited Drug Testing offers comprehensive hair follicle drug testing services right in Hanley Hills, Missouri. For those in need of drug or alcohol testing, our specialty lies in hair analysis, with facilities across the nation equipped to conduct such tests. Typically, you'll need about 1.5 to 2 inches of hair from your head, though body hair may be used. We can test for drugs, alcohol/ETG, plus customizable options.
The preferences for drug screening methods have shifted towards hair follicle testing in recent times. Many employers, judicial systems, and substance abuse counselors now opt for hair tests over the traditional urine analysis. Especially favored by employers with zero-tolerance policies, legal courts, and those on probation, these tests offer a longer detection window, lasting up to 90 days. The sample collection is observed, making it highly tamper-resistant. However, for usage detection within the past five days, urine tests still hold an edge.

Hair analysis is now regarded as an effective means to identify drug and alcohol usage. Hair strands capture biomarkers within their fibers, offering an extended history of alcohol and drug consumption. When taken near the scalp, hair can reveal alcohol and drug presence for up to roughly a three-month period. The collection of hair is straightforward, relatively tamper-proof, and simple to transport.
A sample of 1.5 inches or around 200 hair strands (comparable to a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal quantity for initial testing and subsequent confirmation. For EtG, add-ons, or tests exceeding 10 panels, a specimen of 150mg is preferred. We advise using a jeweler’s scale to measure the specimen. If scalp hair is not present, a similar volume of body hair could be gathered. Reference to head hair specifically means scalp hair. Body hair encompasses all other kinds of hair (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into a lab's system. This process ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry that isn't available through an electronic chain of custody system.
Screening is a preliminary evaluation for drugs of abuse. While Screening is an economical method to disprove drug use for most samples, any positive screening outcome requires confirmation to be court-admissible. There is a necessity for secondary confirmation if a sample tests presumptively positive in Screening.
Upon a presumptive positive result in the Screening stage, additional hair is extracted from the original sample for the Extraction phase. In this step, hair releases drugs at a significantly lower concentration compared to other approaches (like urine or oral fluid), making hair drug testing a challenging methodology.
Confirmation for any positive screening outcome is performed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed prior to confirmation if required. The entire lab procedure from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the standards of 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.
