Hair Follicle Drug Testing - Annapolis, IL

What it is, How it works

Hair analysis is now recognized as a potent resource for detecting substance and alcohol use. Hair captures a prolonged timeline of alcohol and drug usage by encasing biomarkers within the fibers of the hair as it grows. When harvested near the scalp, hair can roughly offer a three-month detection span for alcohol and drug use. Gathering hair is straightforward, relatively secure from tampering, and convenient to transport.

A sample measuring 1.5 inches containing about 200 strands of hair (approximately the thickness of a #2 pencil) from nearest the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, supplementary elements, and/or examinations beyond 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to measure the sample is recommended. If scalp hair cannot be collected, a similar amount of body hair might be used. When mentioning head hair, it is specific to scalp hair alone. Body hair encompasses all other hair variants (facial, axillary, etc.).

Process Overview

The principal procedures in the lab processing of a drug testing outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into a lab’s procedures. It involves ensuring the sample was securely sealed and dispatched correctly, allocating a distinct LAN (Laboratory Accessioning Number), and completing any further data recording not supplied by an electronic chain of custody system.

Screening involves an early rapid assessment for substances of abuse. While Screening is an economical approach to dismiss drug usage across most samples, a confirmed positive result is needed for legal admissibility. Samples that are presumptively positive in Screening necessitate an additional confirming test.

If a specimen is tentatively positive at the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations than in alternative methodologies (e.g., urine or oral fluid), which is why hair drug analysis is considered the most challenging methodology to conduct.

Verification of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with preliminary positive results undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug evaluations can trace drug use for up to 90 days, unlike urine tests which have a limited detection period.
• Challenging to manipulate: Manipulating a hair drug evaluation is notably difficult, enhancing result precision.
• Supplies historical insight: Offers a pattern of substance use over several months, beyond recent usage only.

Limitations:

• Cannot track recent use: It requires roughly 5-7 days for substances to become detectable in hair.
• Expense: Hair drug evaluations typically cost more than other testing methods.
• Result variability: Factors such as hair pigmentation and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: While frequently labeled as "hair follicle tests", the assessment actually examines the hair strand itself 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.
