Hair Follicle Drug Testing - Patch Grove, WI

What it is, How it works

Hair testing is acknowledged as a potent method for detecting drug and alcohol consumption. Hair captures a prolonged history of these substances by embedding biomarkers within the fibers of the growing strand. When collected near the scalp, hair can offer up to about a 3-month detection period for alcohol and other substances. It is easy to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch portion comprising roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for screening and confirmatory purposes. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing is suggested. If scalp hair is not available, a comparable quantity of body hair can be used. Head hair refers strictly to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning comprises the introductory processing of a sample into the lab’s management system. This entails confirming the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any ancillary data input not covered by an electronic chain of custody system.

Screening conducts a preliminary swift assessment for substances of abuse. Though Screening is a cost-efficient means to exclude drug consumption in most samples, a positive result necessitates confirmation to be legally admissible. Samples with presumptive positive outcomes in Screening require a follow-up validation.

If a sample exhibits presumptive positivity at the Screening phase, additional hair is extracted from the initial specimen for Extraction preparation. During this phase, drugs are extracted from hair at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), explaining why hair drug screening is the most complex methodology to undertake.

Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• High resistance to tampering: The difficulty in cheating a hair drug test enhances result accuracy.
• Provides chronological usage data: It unveils a timeline of drug consumption over time, not solely recent use.

Limitations:

• Incapable of recent usage detection: Drugs typically become noticeable in hair around 5-7 days post-consumption.
• Higher cost: Hair drug tests usually carry a higher price point than other testing approaches.
• Result disparities: Elements like hair color and personal differences in growth can influence drug metabolite concentrations in hair.

Note: While commonly dubbed as "hair follicle tests", the examination focuses on the hair strand rather than the hair 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.
