Hair Follicle Drug Testing - White City, IL

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of substances through the capture of biomarkers within the fibers as the strand grows. When collected near the scalp, hair allows for approximately a 3-month window in detecting alcohol and other substances. Hair collection is straightforward, comparatively hard to tamper with, and easily transported.

A sample measuring 1.5 inches with roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample amount for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advisable. Utilizing a jeweler’s scale to weigh the specimen is suggested. Should scalp hair be inaccessible, an equal quantity of body hair can be gathered. References to head hair pertain exclusively to scalp hair while body hair pertains to all other types (such as facial, axillary, etc.).

Process Overview

The four primary steps in the laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial registration of a sample within a laboratory's system. It involves verifying that the sample was securely sealed and transported correctly, allotting a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody framework.

Screening involves a preliminary rapid assessment for drugs of abuse. While cost-effective for excluding drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Any samples that show a presumptive positive in Screening require secondary confirmation.

In the case of a presumptive positive outcome during the Screening phase, more hair is taken from the original specimen and readied for Extraction. This phase involves extracting substances from hair at a concentration markedly lower than other techniques (such as urine or oral fluid), which explains why hair drug analysis is the most complex methodology to execute.

Confirmation of any positive screening result is executed using methods like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as needed. The whole laboratory process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can reveal drug use over a 90-day span, unlike urine tests, which have a shorter detection timeframe.
• Challenging to falsify: Manipulating a hair drug test is exceedingly difficult, thereby enhancing result precision.
• Chronological data provision: It can offer an account of drug consumption patterns over time, not merely recent use.

Limitations:

• Inability to detect recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other drug testing methods.
• Result variations: Elements such as hair color and personal differences in hair growth can influence drug metabolite levels within the hair.

Note: Although often termed "hair follicle tests," the analysis targets 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
