Hair Follicle Drug Testing - Nome, AK

What it is, How it works

Hair analysis has become recognized as an effective method for detecting drug and alcohol consumption. Hair retains a prolonged record of substances by capturing biomarkers within its fibers during growth. When cut near the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and substances. Hair is easy to collect, somewhat resistant to tampering, and convenient for transport.

An ideal sample comprises a 1.5-inch section of roughly 200 hair strands (approximately equivalent to the diameter of a #2 pencil) nearest to the scalp, providing 100mg of hair, ideal for initial tests and verifications. For tests such as EtG, expanded panels, or tests exceeding 10 panels, 150mg is preferred. It's advisable to measure the sample on a jeweler's scale. Should scalp hair be insufficient, a comparable quantity of body hair may be used. Head hair specifically denotes scalp hair, while body hair includes all other varieties (e.g., facial, axillary).

Process Overview

There are four primary steps in processing a drug test result in a laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample within a lab’s system. It involves ensuring the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplemental data not available from an electronic chain of custody system.

Screening comprises an initial rapid assay for drug substances. Although Screening is a cost-efficient method for eliminating drug use in most samples, any positive results need further confirmation for legal admissibility. Samples flagged as presumptively positive during Screening require additional confirmation.

Should a sample indicate a presumptive positive at the Screening stage, additional hair is extracted from the original sample and prepped for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing particularly challenging.

Confirmation of positive Screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, presumptively positive samples undergo washing as necessary. The full laboratory procedure, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can reveal drug use for up to 90 days, as opposed to urine tests, which have shorter detection periods.
• Cheating is challenging: Hair drug evaluations are difficult to falsify, enhancing result accuracy.
• Tracks usage history: This test can identify patterns of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent intake: Drug presence in hair is detectable only after approximately 5-7 days.
• Expense: Typically, hair drug evaluations incur higher costs than other methods.
• Variation in findings: Variables such as hair color and individual hair growth differences can influence the concentration of drugs within hair.

Note: Commonly termed "hair follicle tests", the analysis actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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. 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.
