Hair Follicle Drug Testing - Wiley Ford, WV

What it is, How it works

The utility of hair testing has increasingly been recognized as a significant approach to identifying drug and alcohol consumption. Hair retains information about alcohol and other drugs over an extended period by embedding biomarkers within the strands as they grow. Hair samples taken from close to the scalp can potentially reveal drug and alcohol use over a detection window of up to three months or so. The collection process is straightforward, challenging to tamper with, and logistics for shipping are uncomplicated.

Gathering a sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, considered sufficient for initial analysis and confirmation. Tests such as EtG, add-ons, or those exceeding 10 panels require 150mg of the sample. Utilizing a jeweler’s scale to weigh the specimen is advisable. If no scalp hair is present, a comparable quantity of body hair can be obtained. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The procedure for processing a drug test result in the lab comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab's system. This step includes verifying the integrity of the sample's seal and shipment, generating a unique LAN (Laboratory Accessioning Number), and completing any necessary data entries absent from an electronic chain of custody system.

Screening is a preliminary and efficient method of testing for drug abuse. Though cost-effective for ruling out drug use in most cases, any positive screening must undergo confirmation for court-acceptance. Samples flagged as potentially positive during Screening require further verification.

In instances of a potential positive result during Screening, additional hair is extracted from the original sample for further processing. In the Extraction phase, drugs are isolated from the hair at noticeably lower concentrations compared to alternative methodologies (such as urine or oral fluid), which underscores the complexity of hair drug screening.

Confirmation, conducted using GC/MS, GC/MS/MS, or LC/MS/MS, involves verifying any positive results from Screening. Samples identified as presumptive positives undergo a wash before Confirmation, if necessary. The entire sequence, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which offer a shorter detection timeframe.
• High resistance to tampering: Manipulating the results of a hair drug test is notably challenging, ensuring greater accuracy.
• Chronicles past drug use: It depicts a pattern of drug use over time, beyond merely recent activity.

Limitations:

• Inability to identify recent consumption: Drugs typically become detectable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug testing generally incurs higher costs compared to other methods.
• Result variability: Differences in factors like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Despite being informally called "hair follicle tests", the analysis actually involves the hair strand itself, 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.
