Hair Follicle Drug Testing - Lakebay, WA

What it is, How it works

Hair analysis has emerged as a formidable technique for uncovering drug and alcohol consumption. Hair captures a historical record of substances by embedding biomarkers in the structure of the hair as it grows. When obtained near the scalp, hair can reveal substance use over an estimated 3-month span. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment comprising roughly 200 hair strands (similar to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred amount for both screening and validation. For EtG, add-ons, and/or examinations above 10 panels, 150mg of the hair is ideal. It's advisable to determine the specimen's weight using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be used. When we mention head hair, it specifically pertains to scalp hair. Body hair refers to all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test outcome encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the initial incorporation of a sample into a lab's database. This step ensures the sample was appropriately sealed and delivered, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any supplementary data omissions absent in an electronic custody system.

Screening pertains to a preliminary rapid drug presence assessment. Although Screening is an economical approach to negate drug exposure in most samples, a Screening positive must be validated for courtroom acceptability. Samples that test presumptively positive in Screening necessitate further affirmation.

If Screening marks a sample as presumptively positive, additional hair is extracted from the original sample for Extraction. During this phase, substances are extracted from the hair at a substantially lower concentration than other processes (e.g., urine or oral fluid), rendering hair drug testing the most complex method to execute.

Confirmation of any positive result from Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as warranted before confirmation. The full laboratory operation from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair categorization and conformity to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection window: Hair drug evaluations can identify drug intake for up to 90 days, unlike urine assessments which have a shorter detection timeframe.
• Resistance to tampering: Ensuring a hair drug evaluation is nearly impossible to subvert, enhancing result credibility.
• Offers historical insight: It can disclose a drug use trend over time, beyond immediate usage.

Limitations:

• Unable to identify immediate usage: Drugs generally appear in hair 5-7 days post-use.
• Expense: Hair drug evaluations tend to be pricier compared to alternative methods.
• Result variability: Elements like hair hue and individual growth differences can influence drug metabolite concentrations in hair.

Note: Commonly labeled as "hair follicle tests", the test evaluates the hair shaft 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.
