Accredited Drug Testing provides thorough hair follicle drug assessments at Purdue University, Indiana. Our organization focuses on hair-based drug and alcohol evaluations and boasts testing facilities across every city nationwide ready for hair analysis. Generally, 1.5 to 2 inches of hair from the crown or body can be used. Tests can check for substances, alcohol/ETG, or tailored testing needs.
Recently, drug testing approaches have leaned more towards hair follicle tests. These tests, often preferred by employers, courts, and substance abuse professionals, are favored over the conventional urine tests. Employers with strict anti-drug policies, judicial systems, and probationers benefit from hair follicle tests, mainly due to their extended detection window of up to 90 days. However, urine tests still prove most accurate for recent, within 5 days, usage.

The use of hair testing is increasingly acknowledged as a significant method for detecting alcohol and drug consumption. Hair serves as an extensive historical record by ensnaring biomarkers within the fibers of its growing strands. When clipped close to the scalp, hair can reveal drug and alcohol use over a span of up to three months. Hair collection is straightforward, there's less risk of tampering, and shipping is uncomplicated.
A sample measuring 1.5 inches with around 200 hair strands (akin to a #2 pencil's size) taken nearest to the scalp provides 100mg of hair — an optimal amount for both screening and verification. For EtG or supplementary tests that exceed 10 panels, it's best to have 150mg of the sample. Utilizing a jeweler's scale is advisable for weighing. If head hair isn't obtainable, a comparable quantity of body hair can be used. The term head hair exclusively refers to scalp hair, while body hair indicates any other hair variety (like facial or axillary hair).
Process Overview
The procedure for processing drug test results comprises four stages: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, samples are initially integrated into a laboratory's system. This step includes ensuring the sample was correctly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling in any extra data not covered by an electronic custody chain system.
The Screening stage undertakes a preliminary rapid test for substances of abuse. While it’s a budget-friendly approach for ruling out drug consumption in many samples, a court-admissible positive result requires confirmation. Any samples with a tentative positive outcome in Screening need subsequent verification.
In cases where a sample tests presumptively positive during the Screening phase, additional hair is segregated for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations when compared to other methods (like urine or oral fluids), which is why hair drug testing stands out as the most challenging methodology.
For confirming suspected positive results, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are used. All samples preliminarily testing positive undergo cleansing before confirmation as needed. The comprehensive laboratory process, starting from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and the 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.
