Accredited Drug Testing provides extensive hair follicle drug testing services in St. Clair, Missouri. If a hair drug or alcohol test is necessary, Accredited Drug Testing excels in hair testing and operates testing centers across all cities nationwide to conduct such tests. Typically, 1.5 to 2 inches of hair from the crown or body is used. Hair samples can be analyzed for drugs, alcohol/ETG, or other tailor-made options.
In recent times, hair follicle drug testing has gained popularity as a common method for drug screening. Many employers, judicial systems, and substance abuse professionals prefer it over traditional urine tests. Employers with strict no-drug policies, courts, and probation officers opt for hair follicle drug tests due to their longer detection period, lasting up to 90 days. Although highly reliable, urine tests remain precise for detecting recent drug use within the last 5 days.

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. The hair captures a prolonged history of substance use by embedding biomarkers within the strands’ fibers as they grow. When taken close to the scalp, it offers nearly a 90-day detection period for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section of roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp yields 100mg, the optimal amount for testing and verifying. For EtG, additional tests, and/or panels exceeding ten, a 150mg sample is suggested. Utilizing a jeweler's scale for precise measurement is advisable. If scalp hair cannot be obtained, an equivalent volume of body hair should be collected. When discussing head hair, it implies scalp hair exclusively, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The lab procedure for processing a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the stage where a sample is initially processed within a lab system. It entails confirming the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and finishing any extra data entry absent from an electronic chain of custody system.
Screening entails an initial swift assessment for substance abuse. While Screening is a cost-effective method to eliminate drug presence in most samples, a positive screen must be confirmed to be valid in legal settings. Samples with presumptive positives in Screening require another level of confirmation.
Upon a presumptive positive during the Screening stage, additional hair is extracted from the original sample for preparation in the Extraction stage. Here, drugs are removed from hair at much lower concentrations than seen in other methods (e.g., urine or saliva), making hair drug screening the most challenging methodology to execute.
Confirmation occurs through GC/MS, GC/MS/MS, or LC/MS/MS for any positive screening outcome. All presumptive positive samples are cleansed before confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

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.
