Hair Follicle Drug Testing - Meadow Glade, WA

What it is, How it works

Hair analysis has gained recognition as a valuable method for identifying drug and alcohol consumption. This approach captures a long-term timeline of substance use by embedding biomarkers within the fibers of the strand as it grows. Collected near the scalp, hair can reveal drug and alcohol usage spanning up to roughly three months. It is easy to collect, challenging to tamper with, and straightforward to transport.

A hair sample measuring 1.5 inches, comprising about 200 strands (approximately #2 pencil thickness) closest to the scalp, yields 100mg, which is optimal for both screening and verification. For additional EtG tests or tests exceeding 10 panels, a 150mg collection is advisable. Using a jeweler’s scale to weigh the sample is suggested. In the absence of scalp hair, a similar quantity of body hair may be used. When mentioning head hair, it specifically implies scalp hair, whereas body hair denotes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning starts with integrating a sample into the lab’s system. This step ensures the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by electronic chain of custody systems.

Screening performs an initial, swift assessment for drug presence. While it serves as an economical method to eliminate drug use in most cases, a positive screen must be substantiated to be court-admissible. Samples presumed positive during Screening require confirmation through a secondary process.

For samples flagged positive in Screening, additional hair is extracted from the initial batch for the Extraction process. This step isolates drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making it one of the most challenging drug testing methodologies.

Confirmation for any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo a cleansing phase before confirmation as needed. The comprehensive laboratory workflow, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify substance use up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• Resistance to manipulation: Hair drug testing is difficult to tamper with, enhancing result accuracy.
• Time-trend data: It offers a timeline of drug consumption over periods, not just recent activity.

Limitations:

• Cannot detect very recent use: Drugs take about 5-7 days to become identifiable in hair strands.
• Expense: Hair drug tests typically incur higher costs than alternative testing strategies.
• Result variability: Influences like hair color and individual hair growth differences can impact metabolite concentration levels.

Note: Frequently termed as "hair follicle tests," these tests actually assess the hair strand rather than 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. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
