Hair Follicle Drug Testing - Manchester, MD

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol use. Hair strands capture biomarkers within their fibers, illustrating a long-term record of alcohol and other drugs. A sample close to the scalp can reveal a detection window of up to 3 months for alcohol and other substances. It's straightforward to gather, challenging to tamper with, and simple to transport.

A 1.5-inch segment from around 200 hair strands (comparable to the width of a #2 pencil) next to the scalp yields 100mg, the preferred amount for testing. For further analysis such as EtG, add-ons, and tests beyond 10 panels, 150mg is advised. Employ a jeweler’s scale for precise measurement. When scalp hair is lacking, an equivalent quantity of body hair can be substituted. Note that head hair refers exclusively to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing for drug test results consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial sample handling within a lab's system. This step ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening offers an initial rapid assessment for substance abuse. While it is a cost-efficient approach to negate drug usage for most samples, a positive result necessitates confirmation for court admissibility. Samples testing positive in Screening mandate further verification.

For samples testing positive in Screening, additional hair is sourced from the original sample for Extraction. This involves extracting drugs from the hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most challenging technique to conduct.

Any positive screening result undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are pre-washed before Confirmation, as required. The comprehensive lab process from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug testing can identify drug usage over a span of up to 90 days, unlike urine tests with a shorter timeframe.
• Difficulty to cheat: The challenge in manipulating a hair drug test ensures more precise outcomes.
• Provides historical data: It reveals a pattern of drug consumption over time, beyond just recent use.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Hair drug screening tends to be costlier than alternate testing approaches.
• Variations in results: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Often referred to as "hair follicle tests", the test evaluates 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.
