Hair Follicle Drug Testing - Isanti, MN

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It offers a prolonged historical record of drug and alcohol use by capturing biomarkers within the hair fibers. When sampled near the scalp, hair can deliver up to a three-month detection timeframe for substances. Hair collection is straightforward, challenging to tamper with, and easy to send for analysis.

A 1.5-inch section of around 200 hair strands (roughly matching the width of a #2 pencil) nearest to the scalp is needed to acquire 100mg of hair, which is the optimal sample amount for analysis and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen weighing 150mg is advisable. It's suggested to weigh the hair sample using a jeweler’s scale. If scalp hair cannot be obtained, an equal quantity of body hair is an alternative. When referring to head hair, it specifically means scalp hair; body hair includes other hair types such as facial, axillary, etc.

Process Overview

The primary phases of lab processing for drug test results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a laboratory’s workflow. This entails verifying the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and doing additional data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. Though Screening offers a cost-efficient way to exclude drug use in most cases, positive results require confirmation to be legally defensible. Samples indicating potential positives during Screening necessitate further confirmation.

When a sample tests potentially positive in Screening, additional hair is extracted from the initial sample for the Extraction process. At this stage, drugs are extracted from hair in significantly lower concentrations compared to other methods (such as urine or saliva), making hair drug screening one of the most challenging methodologies.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All potential positive specimens are washed before confirmation if necessary. The lab procedure from Accessioning to Confirmation is conducted following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug usage up to 90 days prior, unlike urine testing, which has a shorter detection span.
• Hard to falsify: The accuracy of hair drug testing is improved due to its difficulty to be cheated.
• Historical usage data: It offers insights into drug usage patterns over time, not just current use.

Limitations:

• Inability to detect recent use: Drugs typically take about 5-7 days post-consumption to become traceable in hair.
• Higher cost: Hair drug tests tend to be more expensive compared to other drug test techniques.
• Result variations: Hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," the testing focuses on analyzing the hair strand rather than 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.
