Accredited Drug Testing offers comprehensive hair follicle drug assessments in Willis, Texas. Specializing in hair drug and alcohol testing, our services are available at testing centers located in numerous cities across the nation. Typically, 1.5 to 2 inches of hair from the scalp are required, but body hair can also be used. Analysis can be conducted to detect drugs, alcohol/ETG, or customized testing options.
The hair follicle drug test is increasingly utilized in recent years as a preferred method for drug screening. Many employers, judicial systems, and substance abuse professionals favor this test over the standard urine test. Employers with zero-tolerance policies, courts, and those on probation often rely on its results. The standout advantage is the longer detection window, typically up to 90 days, with an observed collection process, making it difficult to manipulate. Despite this, urine tests remain the most reliable method for detection of drug use within the last five days.

Hair tests are increasingly recognized as an effective means for identifying drug and alcohol consumption. As hair grows, it embeds biomarkers within its fiber, offering a comprehensive timeline of alcohol and drug exposure. When taken near the scalp, hair samples provide a detection period of up to around three months for alcohol and drugs. Sample collection is straightforward, the risk of tampering is low, and samples are easy to transport.
A sample size of 1.5 inches, comprising roughly 200 hair strands (about the thickness of a #2 pencil) and taken nearest the scalp, yields 100mg of hair, which is optimal for testing and validation. For EtG, additional tests, or those exceeding 10 panels, a specimen weighing 150mg is suggested. A jeweler’s scale is recommended for precise measurement. In cases where scalp hair isn’t available, an equivalent amount of body hair can be collected. The term "head hair" specifies only scalp hair, whereas "body hair" includes all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a lab's system. This stage includes verifying the sample’s seal and proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry not handled by an electronic chain of custody system.
Screening is the preliminary evaluation for substance abuse. Although Screening provides an economical way to discard drug usage in most samples, any positive results must be verified for court admissibility. Samples that test positive at this stage necessitate a further confirmation.
For samples indicated as positive during Screening, additional hair is acquired from the initial sample and prepped for Extraction. This phase extracts drugs from hair in significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening a complex methodology.
The Confirmation of positive screenings is executed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. From Accessioning through Confirmation, the entire lab process is assessed according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation 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.
