Hair Follicle Drug Testing - Wenonah, IL

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and substances by capturing biomarkers within its growing fibers. When taken near the scalp, hair offers up to a roughly 3-month window for detecting alcohol and other substances. Hair is straightforward to collect, somewhat tough to tamper with, and simple to send.

A sample of 1.5 inches or around 200 strands of hair (similar in size to a #2 pencil) closest to the scalp yields 100mg, the optimal sample size for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to weigh the sample on a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. By head hair, we mean only scalp hair. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a lab's system. This step involves confirming the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not furnished by an electronic chain of custody system.

Screening conducts an initial quick check for abusive substances. While Screening is a cost-efficient method to eliminate drug use in most samples, a positive screen necessitates confirmation to be valid in a legal context. Samples flagged as presumptively positive in Screening require additional confirmation.

If a sample is suspected positive in the Screening phase, additional hair is taken from the initial sample for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation for any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation if needed. The entire lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can detect drug use for up to 90 days, unlike urine tests with a shorter timeframe.
• Challenging to deceive: Hair drug testing is challenging to cheat, enhancing result accuracy.
• Offers historical insight: It provides a pattern of drug use over time, not just recent activity.

Drawbacks:

• Inability to detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more than other methods.
• Result variability: Factors like hair color and growth variations can influence drug metabolite levels in hair.

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