Based in Granbury, Texas, Accredited Drug Testing provides seamless hair follicle drug screening services. Whether in need of hair drug or alcohol assessments, our specialization lies in hair analysis, available at testing locations nationwide. Generally requiring 1.5 to 2 inches of hair from the head or body, our tests can identify drug and alcohol/ETG presence, or cater to specific hair testing requirements.
More organizations are turning to hair follicle drug testing over traditional methods. Businesses with strict anti-drug policies, legal entities, and substance abuse experts often favor hair sampling over urine tests. This method benefits from identifying drug use over a much wider window, up to 90 days, through an observed collection process, offering secure and tamper-proof results, while urine testing remains better for detecting very recent use.

The utilization of hair testing is increasingly recognized as a potent method for detecting drug and alcohol consumption. Hair captures a lengthy record of substances within the strands as they grow, trapping biomarkers. If cut close to the scalp, hair can reflect a usage timeline of around 3 months for alcohol and various drugs. Its collection is straightforward, it is rather resistant to tampering, and is convenient for transport.
Gathering a 1.5-inch portion consisting of approximately 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp yields 100mg, an optimal amount for both screening and verification. For EtG, additional analyses, or tests exceeding 10 panels, a 150mg quantity is preferable. We advise weighing the sample on a jeweler's scale. Should scalp hair be unavailable, an equivalent measure of body hair can be taken. In terms of head hair, it specifically denotes scalp hair. Conversely, body hair includes all other types (e.g., facial, axillary).
Process Overview
The laboratory analysis of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a sample into the lab's system. This procedure entails confirming the sample's appropriate sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent in an electronic chain of custody system.
Screening performs an initial swift assessment for drug misuse. While cost-efficient for excluding drug use in most specimens, a positive result in Screening necessitates confirmation for court admissibility. Samples flagged as presumptively positive during Screening require a follow-up confirmation.
Samples indicating potential positivity in the Screening phase have additional hair extracted for the Extraction phase. Here, drugs are isolated from the hair at lower concentrations compared to other methods (like urine or oral fluids), illustrating the technical complexity of hair drug tests.
Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples labeled as presumptive positives are cleaned before confirmation if needed. The entire lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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.
