Hair Follicle Drug Testing - Larch Way, WA

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. The long-term record of drug and alcohol use is captured as biomarkers within the hair strand’s growing fibers. When acquired near the scalp, hair offers a detection period of roughly three months for alcohol and other drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches and comprising around 200 hair strands (approximating the width of a #2 pencil) nearest to the scalp yields 100mg, an ideal amount for screening and verifying. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is suggested. Employ a jeweler’s scale for precise specimen weighing. If scalp hair is missing, an equivalent quantity of body hair can be sourced. Reference to head hair pertains solely to scalp hair. In contrast, body hair encompasses all other types, such as facial and axillary hair.

Process Overview

The laboratory process of analyzing a drug test result incorporates the key steps of Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the foremost handling of a sample within a lab's framework. It verifies that the sample was adequately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any requisite documentation absent from an electronic chain of custody system.

Screening provides an initial swift evaluation for drug misuse. Though cost-effective for discarding drug use in most cases, a positive screen necessitates confirmation for legal acceptability. Samples deemed presumptively positive via Screening mandate a further confirmation step.

For samples flagged as presumptively positive in the Screening phase, additional hair is curated from the initial sample for Extraction. This step retrieves drugs at notably lower concentrations than alternative methods (e.g., urine or oral fluids), establishing hair drug screening as the most challenging technique to execute.

Positive screening outcomes undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples are cleansed before confirmation, as needed. The comprehensive lab process from Accessioning to Confirmation adheres to standards by both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests have the capability to identify drug use over a span of up to 90 days, unlike urine tests, which offer a shorter detection duration.
• Resistance to tampering: The complexity of falsifying a hair drug test ensures greater accuracy in results.
• Reveals historical usage patterns: It illuminates drug use trends over time, not only recent intake.

Limitations:

• Incapable of identifying recent consumption: A lag of approximately 5-7 days exists before drugs become detectable in hair.
• Expense: Compared to other drug testing methods, hair drug tests incur higher costs.
• Result fluctuations: Elements like hair color and personal differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: Although often termed "hair follicle tests", the assessment evaluates the hair shaft rather than the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. 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.
