Hair Follicle Drug Testing - Mount Rainier, WA

What it is, How it works

Hair analysis is gaining recognition as a potent method for identifying the use of alcohol and drugs. The fibers in growing hair strands trap biomarkers, offering a prolonged historical overview of substance usage. Hair samples taken close to the scalp can reflect drug or alcohol consumption over a span of up to three months. Hair gathering is straightforward, resistant to tampering, and easy to transport.

A 1.5-inch sample consisting of around 200 hair strands (about the thickness of a #2 pencil) from the scalp typically weighs 100mg, which is optimal for both screening and confirmation processes. For tests involving EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent mass of body hair can be used. "Head hair" specifically denotes scalp hair. "Body hair" encompasses all other types (such as facial or axillary hair).

Process Overview

There are four primary stages in lab processing for a drug test result: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially incorporated into the lab’s system. This involves ensuring the sample’s proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and completing any additional data capture not covered by an electronic chain of custody system.

Screening provides an initial rapid assessment for substances of abuse. Though Screening is a cost-efficient method to disprove drug use in most cases, a positive result requires confirmation to be court-admissible. Samples that are presumptively positive in Screening necessitate subsequent confirmation.

For samples deemed presumptively positive at the Screening phase, further hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at notably lower concentrations than those in other samples types (such as urine or oral fluid), which makes hair drug screening a particularly challenging methodology.

Positively screened results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if necessary. The whole lab process from Accessioning through Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair standard and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to three months back, unlike urine tests which have a shorter detection time frame.
• Difficult to manipulate: Cheating a hair drug test poses significant challenges, ensuring more reliable results.
• Captures drug use trends: It reveals drug use patterns over extended periods, not just recent consumption.

Limitations:

• Cannot identify recent consumption: Drugs become detectable in hair about 5-7 days following use.
• Expense: Hair drug tests usually incur higher costs than other drug-testing techniques.
• Result variability: Factors like hair color and personal hair growth rate can influence drug metabolite concentrations in hair.

Note: Although commonly known as "hair follicle tests," the analysis actually involves 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.
