Hair Follicle Drug Testing - Terrebonne, MN

What it is, How it works

Hair analysis has emerged as a potent instrument for detecting drug and alcohol usage. Hair encapsulates a prolonged record of alcohol and drug consumption by embedding biomarkers within the strands of growing hair. When extracted near the scalp, hair can offer up to nearly a three-month detection timeframe for alcohol and drug substances. Hair collection is straightforward, somewhat challenging to tamper with, and convenient for shipping.

A 1.5-inch section containing around 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields approximately 100mg of hair, which is the optimal quantity for screening and verification. For EtG, add-ons, and/or examinations exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. In the absence of scalp hair, a comparable volume of body hair can be gathered. In the context of head hair, this refers exclusively to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The four essential phases in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab's system. This process includes ensuring the sample was correctly sealed and delivered, allotting a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent from an electronic chain of custody system.

Screening is a preliminary swift inspection for drugs of abuse. While Screening provides an economical method to eliminate drug usage in most samples, a positive screen must be verified to be legally acceptable. Any samples preliminarily positive in Screening demand secondary confirmation.

If a sample tests preliminarily positive in the Screening step, additional hair is extracted from the initial collection and prepped for Extraction. This phase isolates drugs from hair at considerably lower concentrations than other procedures (e.g., urine or oral fluid), which renders hair drug screening the most challenging procedure to execute.

Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes a wash before confirmation, as necessary. The complete laboratory operation from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug usage for up to 90 days, unlike urine tests which have a shorter detection period.
• Challenge to manipulate: Manipulating a hair drug test is quite arduous, ensuring more precise results.
• Enables historical insight: It can offer a trend of drug consumption over time, rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs become discernible in hair approximately 5-7 days post-exposure.
• Expense: Hair drug evaluations typically cost more than alternative drug testing approaches.
• Results variability: Elements such as hair pigmentation and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: While commonly labeled as "hair follicle tests", the assessment itself evaluates the hair strand, 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.
