Hair Follicle Drug Testing - Sweatman, MS

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by embedding biomarkers within the strands as they grow. When sourced near the scalp, hair can offer nearly a 3-month window for detecting alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is hassle-free.

A 1.5-inch segment consisting of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimum sample for analysis and confirmation. For EtG, additional tests, or testing beyond 10 panels, 150mg is advised. Using a jeweler's scale for measuring the sample is recommended. If scalp hair cannot be obtained, a similar quantity of body hair can be collected. "Head hair" refers solely to scalp hair, while "body hair" encompasses all other types, such as facial and axillary hair.

Process Overview

There are four principal procedures in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves entering the sample into a lab’s system. This encompasses confirming that the sample was sealed and transported correctly, generating a random Laboratory Accessioning Number (LAN), and performing any additional data input not covered by an electronic chain of custody method.

Screening provides an initial rapid assessment for substances of abuse. While Screening is cost-efficient for dismissing drug use in most cases, a positive result requires confirmation to be legally viable. Any samples with presumptive positive findings in Screening necessitate a follow-up confirmation.

Should a sample be presumptively positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted at lower concentrations compared to other methods such as urine or oral fluid, making hair drug testing a complex task.

Any positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is audited under both the College of American Pathologists (CAP) Hair designation and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more confined detection window.
• High resistance to tampering: Cheating a hair drug test is extremely challenging, thus enhancing result accuracy.
• Offers historical insight: It reveals a pattern of drug consumption over time, rather than just recent use.

Limitations:

• Incapable of identifying recent use: Drugs take roughly 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically more costly than alternative drug testing techniques.
• Result variability: Variances such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", the actual test assesses the hair strand rather than the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Sweatman, MS, the superiority of hair follicle testing becomes evident when compared to urine testing.

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
