Hair Follicle Drug Testing - Patoka, IL

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying the presence of drugs and alcohol. Through capturing biomarkers within the strands of hair, it provides a long-term record. When samples are taken near the scalp, they can offer up to a 3-month window for detecting alcohol and other substances. The collection process for hair is straightforward, relatively tamper-proof, and convenient for shipping.

A 1.5-inch length consisting of around 200 hair strands (comparable to the width of a #2 pencil) near the scalp presents 100mg of hair, considered ideal for both screening and confirmation. In cases involving EtG, additional substances, or more than 10-panel tests, 150mg of hair is recommended. Specimens should be measured using a jeweler’s scale, and if scalp hair isn’t available, a similar amount of body hair can be used. Head hair denotes only scalp hair, while body hair encompasses all other types, including facial and axillary hair.

Process Overview

There are four primary stages in the lab processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial integration into a lab's system. This phase ensures the sample's seal and shipment integrity, assigns a unique LAN (Laboratory Accessioning Number), and fills any data gaps not covered by an electronic chain of custody system.

In the Screening phase, there’s an initial examination for substances of abuse. Although this method is cost-efficient for eliminating drug use in most samples, positive results require confirmation for court acceptance, necessitating additional verification of any presumptively positive samples.

If a sample is positive in the Screening stage, additional hair is taken from the starting specimen for Extraction, where drugs are extracted at much lower concentrations than other methods (e.g., urine or oral fluid). Thus, hair drug screening is considered the most challenging method to carry out.

Confirmation of any positive screening outcome is handled via GC/MS, GC/MS/MS, or LC/MS/MS. All ostensibly positive samples undergo washing before confirmation if required. The complete laboratory procedure, from Accessioning to Confirmation, receives evaluation under CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can identify drug use over a span of up to 90 days, unlike urine tests that offer a shorter window.
• Resistance to tampering: Hair drug tests are notably hard to manipulate, ensuring more reliable results.
• Chronological insights: These tests can reveal drug use patterns over time, not just recent occurrences.

Limitations:

• Recent use detection: It usually takes about 5-7 days for drugs to be evident in hair.
• Expense: Generally, hair drug analyses cost more than other testing approaches.
• Result variability: Drug metabolite concentrations in hair can be influenced by hair color and individual growth differences.

Note: While these are often called "hair follicle tests", the analysis focuses on 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.
