Hair Follicle Drug Testing - Friendship, WI

What it is, How it works

Hair testing is now regarded as an effective tool for identifying drug and alcohol consumption. Hair delivers a long-term record of alcohol and drug usage by capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair offers approximately a 3-month detection timeframe for both alcohol and drugs. Hair is straightforward to collect, somewhat resistant to tampering, and simple to transport.

A 1.5-inch sample comprising around 200 strands of hair (similar to the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for analysis and confirmation. For EtG, supplementary tests, and/or tests exceeding 10 panels, a sample of 150mg is advisable. Utilizing a jeweler's scale is recommended for weighing the sample. If scalp hair is not present, an equivalent quantity of body hair can be used. The reference to head hair pertains solely to scalp hair, while body hair encompasses other types (like facial, axillary, etc.).

Process Overview

The primary steps involved in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial inclusion of a sample into a lab's system. This process confirms the sample was correctly sealed and sent, allocates a random LAN (Laboratory Accessioning Number), and completes any extra data entry not provided by an electronic chain of custody system.

Screening provides a preliminary and rapid evaluation for drug abuse. Although Screening is an economical method to dismiss drug use in most samples, a positive screen must be verified to be permissible in judicial proceedings. Samples that initially test positive in Screening require an additional confirmation.

If a sample presumptively tests positive during Screening, additional hair is extracted from the initial batch and prepared for Extraction. In this process, drugs are removed from the hair at a concentration much lower than in other techniques (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to execute.

Confirmation of any positive results from the screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can uncover drug usage for as long as 90 days, surpassing urine tests that have a more limited detection duration.
• Hard to manipulate: Cheating a hair drug test is challenging, enhancing result accuracy.
• Yields historical trends: This test conveys a drug usage pattern over a period, rather than just recent use.

Limitations:

• Inability to detect recent usage: Drugs typically become detectable in hair after about 5-7 days.
• Higher expense: Hair drug tests usually cost more than other drug testing techniques.
• Result variability: Factors such as hair pigmentation and individual differences in hair growth can alter the concentration of drug metabolites in hair.

Note: Although frequently referred to as "hair follicle tests", the analysis itself examines the hair strand, not the follicle underneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Friendship, WI, hair follicle tests surpass urine tests by offering greater detection accuracy and reliability. They detect drug use from a much larger timeframe than urine tests.

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.
