Hair Follicle Drug Testing - Prairie City, IL

What it is, How it works

Hair analysis has emerged as a formidable method for identifying drug and alcohol use. Hair captures a prolonged record of substance intake by embedding biomarkers within the structure of the developing hair strand. When taken near the scalp, hair offers a roughly 3-month detection period for alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.

A 1.5-inch hair segment consisting of around 200 strands (about the thickness of a #2 pencil) closest to the scalp provides 100mg, which is the preferred sample size for analysis and verification. For EtG, additional panels, or testing beyond 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not available, a similar quantity of body hair can be taken. Scalp hair exclusively refers to head hair. Body hair encompasses all other varieties (facial, underarm, etc.).

Process Overview

The principal stages in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory’s framework. This phase confirms proper sealing and dispatch of the sample, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of misuse. While screening is an economical approach to exclude drug usage in most samples, a positive result requires verification to be valid in legal settings. Samples that yield a presumptive positive in Screening necessitate further confirmation.

Should a sample be presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. At this phase, drugs are isolated from hair at significantly lower concentrations than in alternative methods (e.g., urine or saliva), underscoring why hair drug analysis is the most challenging method to execute.

Verification of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptive positive are washed before confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug screening identifies drug use for as long as 90 days, unlike urine tests which offer a briefer detection window.
• Hard to manipulate: Cheating a hair drug test is exceptionally difficult, thereby enhancing result accuracy.
• Provides temporal data: It highlights a history of drug consumption over time, not merely recent usage.

Limitations:

• Unable to spot recent use: Detectability of drugs in hair takes about 5-7 days.
• Expense: Hair drug assessments generally incur higher costs compared to other drug testing techniques.
• Result variance: Elements such as hair color and individual differences in hair growth might influence the level of drug metabolites in hair.

Note: Although frequently termed as "hair follicle tests," the examination evaluates the hair shaft 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.
