Hair Follicle Drug Testing - Klahanie, WA

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. It provides a prolonged timeline of substance use by embedding biomarkers within the hair strand's fibers. When hair is harvested near the scalp, it offers roughly a three-month period for detecting substances. Hair collection is straightforward, fairly resistant to tampering, and convenient to transport.

A hair sample of 1.5 inches, containing approximately 200 strands (akin to the girth of a #2 pencil), secured closest to the scalp, yields 100mg – the preferred quantity for both screening and verification. For EtG additions or tests exceeding ten panels, 150mg of the hair is suggested. Measurement of the sample using a jeweler’s scale is advisable. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. The term head hair specifically refers to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory protocol for processing drug tests includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary handling of a specimen within the lab's framework. This step ensures the sample was properly sealed and delivered, assigns an arbitrary LAN (Laboratory Accessioning Number), and fulfills any additional documentation not covered by a digital chain of custody system.

Screening performs an initial, swift assessment for misuse of substances. Although Screening is a budget-friendly strategy to eliminate drug presence in most samples, a positive outcome necessitates validation for legal admissibility. Any specimens showing presumptive positive results during Screening require secondary verification.

If the Screening phase indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, the method extracts drugs from hair at significantly lower concentrations than other procedures (e.g., urine or saliva), underscoring the complexity of performing hair drug testing.

Validation of any positive screening is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as deemed necessary. The complete lab process from Accessioning through to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation protocols.

Benefits of hair drug assessment:

• Extended detection period: Hair tests can identify drug consumption for up to 90 days, as opposed to urine assessments with narrower detection spans.
• Resilience against tampering: Cheating a hair test is notably challenging, enhancing result accuracy.
• Chronological usage data: Offers insight into long-term substance patterns, not solely recent intake.

Drawbacks:

• Inability to pinpoint immediate usage: It takes roughly 5-7 days for drugs to show in hair strands.
• Expense: Hair drug evaluations typically incur higher costs than other testing approaches.
• Potential variability: Variables like hair pigmentation and individual hair growth rates may influence drug metabolite concentration in the hair.

Note: Often mentioned as "hair follicle tests," this analysis focuses on the hair strand, excluding 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.
