Hair Follicle Drug Testing - Chevy Chase Section Three, MD

What it is, How it works

Hair analysis has emerged as an effective method for detecting substance and alcohol consumption. Hair captures a lengthy record of alcohol and drug intake by encapsulating biomarkers within the fibers of the growing hair strand. When gathered near the scalp, the hair sample can offer up to roughly a 3-month detection period for alcohol and other substances. Hair is easy to obtain, hard to alter, and convenient to transport.

A 1.5-inch segment of around 200 hairs (approximately the diameter of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal amount for both testing and verification. For EtG, additional tests, and/or assessments exceeding 10 panels, a sample of 150mg is suggested. We propose measuring the sample using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair is collectable. Head hair specifically refers to scalp hair only. Body hair encompasses all other kinds (such as facial, axillary, etc.).

Process Overview

The primary stages in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary management of a sample into a lab’s database. This encompasses checking that the sample was appropriately sealed and transported, allotting a random LAN (Laboratory Accessioning Number), and completing any further information input not given by an electronic chain of custody system.

Screening entails a swift preliminary test for abusive drugs. While Screening economically excludes drug use in the bulk of cases, a positive screen requires validation for admissibility in legal proceedings. Any samples that are tentatively positive in Screening necessitate additional confirmation.

Should a sample show tentative positivity in the Screening phase, further hair is extracted from the initial sample and readied for Extraction. During this step, drugs are drawn from hair at a significantly lower density than with other methods (e.g., urine or saliva), which makes hair drug analysis the most challenging procedure to conduct.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo washing before confirmation if needed. The whole lab process from Accessioning to Confirmation is scrutinized following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection period: Hair drug analyses can identify drug use for up to 90 days, unlike urine tests which have a shorter detection range.
• Hard to falsify: Cheating on a hair drug analysis is exceedingly tough, thereby enhancing result reliability.
• Delivers historical insights: It can offer a timeline of drug consumption over a set interval, not just recent usage.

Limitations:

• Cannot identify recent consumption: It takes about 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug analyses are frequently costlier than other drug testing techniques.
• Outcome variability: Elements like hair color and unique differences in hair growth can influence the level of drug metabolites in the hair.

Note: While regularly termed "hair follicle tests", the examination itself analyzes the hair strand and 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.
