Hair Follicle Drug Testing - Paddock Lake, WI

What it is, How it works

The use of hair testing has become recognized as an effective method for detecting drug and alcohol consumption. Hair can capture a comprehensive history of alcohol and other substances by trapping biomarkers within the growing hair fibers. When collected near the scalp, hair offers a detection window of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch sample comprising about 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp can yield 100mg of hair, which is the optimal sample size for both screening and confirmation. For tests involving EtG, additional substances, and/or more than 10 panels, 150mg of the specimen is advised. It's best to use a jeweler’s scale for weighing the specimen. If scalp hair isn’t available, an equivalent amount of body hair can be used. References to head hair pertain to scalp hair exclusively. Body hair encompasses all other types like facial and axillary.

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially processed into a laboratory’s system. This process includes confirming the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that isn't provided by an electronic chain of custody system.

Screening provides an initial swift check for drug abuse. It is an economical way to exclude drug usage in most samples; however, a positive screen must be confirmed to be valid in legal proceedings. Any samples that are presumptively positive during Screening require a secondary confirmation.

For samples that appear positive in the Screening phase, additional hair is extracted from the initial specimen and set up for Extraction. This step involves extracting drugs from hair at a considerably lower concentration than with other approaches (e.g., urine or oral fluid), rendering hair drug screening one of the most complex methodologies to conduct.

Confirmation of a positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before Confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, whereas urine tests have a shorter detection window.
• Difficulty to cheat: Cheating a hair drug test is exceedingly difficult, increasing the accuracy of results.
• Provides historical data: It can reveal a pattern of drug use over a period, not just recent use.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Hair drug tests are typically more costly than other drug testing methods.
• Variations in results: Factors like hair color and individual differences in hair growth can impact the drug metabolite concentration in the hair.

Note: Though they are often called "hair follicle tests," the analysis is on the hair strand, not the follicle underneath 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.
