Hair Follicle Drug Testing - Palos Hills, IL

What it is, How it works

Hair analysis has emerged as an effective approach for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug involvement by embedding biomarkers within the strands. When sampled near the scalp, hair can reveal a detection period of roughly 3 months for alcohol and drugs. Hair is straightforward to obtain, resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches, consisting of about 200 hair strands (comparable in diameter to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, supplementary tests, and/or panels beyond 10, a 150mg specimen is advisable. We propose using a jeweler’s scale for weighing the specimen. If scalp hair isn't available, an equivalent amount of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other forms (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially integrated into the lab’s system. This phase ensures the sample is properly sealed and transported, a random LAN (Laboratory Accessioning Number) is assigned, and any lacking data not provided by an electronic chain of custody system is entered.

Screening performs a preliminary examination for drugs of abuse. Although Screening offers a cost-effective method to eliminate drug use on most samples, a positive result needs subsequent confirmation for legal admissibility. Samples that are tentatively positive in Screening must undergo secondary confirmation.

In cases where a sample is tentatively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. At this point, drugs are withdrawn from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), which is why hair drug screening is among the most challenging methodologies.

Verification of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Every potentially positive sample undergoes washing before confirmation, if required. The entire procedure from Accessioning to Confirmation is examined following both the CAP (College of American Pathologists) Hair criteria and accreditation under ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests can uncover drug usage for as long as 90 days, unlike urine tests which offer a shorter timeframe.
• Challenging to deceive: Hair drug tests are difficult to manipulate, resulting in more precise outcomes.
• Offers historical insight: It can illustrate a drug use pattern over a time span, not just recent use.

Limitations:

• Inability to detect recent usage: Drugs require about 5-7 days to become perceptible in hair.
• Expense: Generally, hair drug tests are pricier than alternative testing approaches.
• Result disparities: Elements such as hair color and individual hair growth rates can influence drug metabolite concentrations in the hair.

Note: Though commonly termed "hair follicle tests", the analysis targets the hair strands, not the follicles beneath the scalp.

Why Hair Follicle Testing Beats 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.
