Hair Follicle Drug Testing - Mclaurin, MS

What it is, How it works

Hair analysis is increasingly recognized as an effective means for spotting both drug and alcohol consumption. Hair captures long-term substance use history by embedding markers within its growing strands. When sourced closely to the scalp, it offers an approximate three-month detection span for alcohol and narcotics. Hair is straightforward to gather, hard to fake, and convenient to send.

A section of hair, measuring 1.5 inches with around 200 strands (approximately the width of a #2 pencil) from near the scalp, provides 100mg of hair—perfect for analysis and validation. For EtG, supplemental tests, and tests exceeding 10 panels, 150mg of sample is preferable. We advise using a jeweler’s scale to weigh it. If scalp hair is lacking, a comparable mass of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" covers all other types (such as facial and axillary hair).

Process Overview

The primary phases in the lab processing of drug test findings include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary integration of a sample into a lab's system. This process involves ensuring the sample was correctly sealed and dispatched, allotting a randomized LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not captured by an electronic custody chain system.

Screening offers an introductory rapid evaluation for substances of abuse. While it economically dismisses drug use in most samples, a positive screening needs authentication to hold up legally. Samples detected as positive during Screening necessitate another level of verification.

If Screening suggests a positive finding, additional hair is taken from the original sample for Extraction. Drugs are removed from hair at much lower concentrations here than through other means (e.g., urine or oral fluids), rendering hair drug screening a challenging method to execute.

Confirmation for screened positive results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing pre-confirmation as necessary. The full lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug examinations can trace drug use back up to 90 days, while urine tests offer a more restricted timeframe.
• Hard to manipulate: Hair drug assessments are notably difficult to tamper with, resulting in more precise outcomes.
• Shows usage trends: Offers a record of drug consumption over time, beyond just recent activity.

Limitations:

• Not for recent use: Drugs require about 5-7 days to become obvious in hair.
• Expense: Hair drug analyses often carry a higher price tag compared to other methods.
• Result variability: Individual hair features, like color and growth variance, can modify substance metabolite levels in hair.

Note: Though commonly dubbed "hair follicle tests," these procedures actually scrutinize the hair strand, not 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.
