Hair Follicle Drug Testing - Grundy Center, IA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term drug and alcohol history by embedding biomarkers within the strands as they grow. When hair is collected from near the scalp, it can offer up to roughly a 3-month detection timeframe for drugs and alcohol. The collection process is straightforward, the possibility of tampering is relatively low, and it's easy to transport.

A sample consisting of a 1.5-inch section of approximately 200 hair strands (similar in size to a #2 pencil) from close to the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-on tests, and tests exceeding 10 panels, a sample size of 150mg is advised. It's best to determine the sample's weight using a jeweler's scale. If scalp hair cannot be obtained, a comparable quantity of body hair can be used. "Head hair" refers exclusively to hair from the scalp, while "body hair" encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory handling of a drug test result consists of the following main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial sample processing stage into the lab's system. This step includes confirming the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and addressing any additional data requirements not fulfilled by an electronic chain of custody system.

Screening is a preliminary, swift assessment for detecting drugs of abuse. While it is a cost-efficient method for dismissing drug usage in most samples, any positive result obtained from Screening must be confirmed to be permissible in legal proceedings. Samples indicating a presumptive positive result in Screening necessitate a secondary confirmation.

For samples showing a presumptive positive during Screening, additional hair is extracted from the initial sample and prepped for the Extraction process. In this phase, drugs are extracted from hair at a considerably lower concentration compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Any positive result in the screening must be confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicated as presumptively positive are washed before confirmation if needed. The whole laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can uncover drug use for as long as 90 days, while urine tests have a more limited detection period.
• Challenging to manipulate: Cheating a hair drug test is very difficult, resulting in more reliable outcomes.
• Provides historical insights: It supplies a pattern of drug use over a duration, not merely recent consumption.

Limitations:

• Unable to identify recent use: Drugs typically require 5-7 days to become detectable in hair.
• Cost: Hair drug tests tend to be costlier than other drug testing techniques.
• Result variability: Elements such as hair color and individual variations in hair growth can influence drug metabolite concentration in hair.

Note: Despite being often referred to as "hair follicle tests", these tests analyze the strand of hair rather than the follicle located 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.
