Hair Follicle Drug Testing - Federal Way, WA

What it is, How it works

Utilizing hair testing has become recognized as a significant method for uncovering drug and alcohol consumption. Hair serves as a long-term record of drug and alcohol use by embedding biomarkers within the strands of hair as they grow. When clipped near the scalp, hair can reveal a detection period of up to around three months for substances, including alcohol. Collection of hair is straightforward, relatively tamper-resistant, and convenient for transport.

A 1.5-inch batch of about 200 hair strands (resembling the thickness of a #2 pencil) taken as close as possible to the scalp can yield 100mg of hair, which is the optimal quantity for both screening and confirmatory analysis. For tests involving EtG, additional elements, and/or when exceeding 10 panels, 150mg of hair is suggested. We advise measuring the hair with a jeweler's scale. If scalp hair can't be obtained, a comparable amount of body hair may be used. By "head hair," we mean only hair from the scalp. "Body hair" encompasses other kinds of hair (such as facial, axillary, etc.).

Process Overview

The key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample into a lab’s system. This involves ensuring the sample is properly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and filling any extra data gaps not covered by an electronic chain of custody system.

Screening involves a preliminary rapid check for drugs of abuse. Though Screening is economically efficient for excluding drug usage in most samples, a positive screen must be verified for court admissibility. Samples that show a presumptive positive in Screening need a subsequent confirmation.

If a sample registers as presumptively positive during the Screening phase, additional hair is extracted from the original sample in preparation for Extraction. This phase involves isolating drugs from hair at significantly lower concentrations than with other methods (like urine or oral fluid), hence why hair drug screening is one of the most challenging methods to execute.

To verify any positive screening outcome, GC/MS, GC/MS/MS, or LC/MS/MS methods are employed. All samples with presumptive positives undergo necessary washing prior to confirmation. The full lab process from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, contrary to urine tests that have a less extensive detection period.
• Difficult to manipulate: Manipulating a hair drug test is quite challenging, ensuring more trustworthy results.
• Offers historical insight: It allows for a usage pattern over time, not limited to recent usage.

Limitations:

• Incapable of detecting recent usage: Approximately 5-7 days are needed for drugs to appear in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing options.
• Result variability: Factors like hair color and individual hair growth differences can influence the drug metabolite levels in hair.

Note: Although often called "hair follicle tests", it is the hair strand that is analyzed, 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.
