Hair Follicle Drug Testing - Dardenne Prairie, MO

What it is, How it works

Hair analysis has increasingly become regarded as an effective measure for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and other substances by capturing biomarkers within the fibers of the growing hair shaft. When taken near the scalp, hair can deliver a detection span of up to nearly three months for alcohol and various drugs. Hair is easy to gather, relatively challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches with around 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and verification. For tests involving EtG, additional markers, and/or over 10 panels, 150mg of the sample is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not obtainable, a comparable quantity of body hair can be used. When mentioning head hair, it pertains exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four pivotal steps in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the starting phase of processing a sample in a lab’s system. It involves checking that the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not furnished by an electronic chain of custody system.

Screening consists of an initial rapid check for drugs of abuse. Although Screening is an economical method to exclude drug use in the majority of samples, a positive screen must be validated to be regarded as valid in court. Samples marked presumptive positive in Screening require an additional confirmation.

If a sample is found presumptive positive during the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs are separated from hair at a significantly lower concentration compared to other methodologies (e.g., urine or oral fluid), which is why hair drug screening is considered the most complex method to execute.

Any positive screening outcome is validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleaned before confirmation as necessary. The whole lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair directive and the accreditation to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, in contrast to urine tests, which have a shorter detection period.
• Resistance to tampering: Manipulating a hair drug test result is highly challenging, increasing the accuracy of the results.
• Offers historical insights: It provides an overview of drug usage patterns over time, rather than just recent activity.

Limitations:

• Inability to detect recent usage: It requires around 5-7 days before drugs become detectable in hair.
• Higher cost: Hair drug tests typically incur higher expenses compared to other drug testing methods.
• Result variability: Aspects like hair color and individual hair growth differences can influence the levels of drug metabolites present in the hair.

Note: While commonly termed "hair follicle tests", the actual test assesses the hair strand and 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.
