Hair Follicle Drug Testing - Mark, IA

What it is, How it works

Hair analysis has emerged as a robust mechanism for identifying drug and alcohol consumption. Hair captures a comprehensive history of substance use by embedding biomarkers within the strands. When sourced near the scalp, it can reveal up to a three-month period of drug and alcohol consumption. Hair collection is straightforward, challenging to tamper with, and convenient for transport.

A 1.5-inch segment comprising around 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the preferred specimen amount for both screening and confirmation. For EtG, additional assessments, and tests exceeding 10 panels, 150mg is preferred. Using a jeweler’s scale to measure the sample is suggested. In the absence of scalp hair, a comparable amount of body hair is usable. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, underarm, etc.).

Process Overview

There are four central stages in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the sample's initial integration into the lab’s system. This entails ensuring the sample's proper sealing and shipping, allotting a unique LAN (Laboratory Accessioning Number), and executing supplementary data entry absent in an electronic chain of custody system.

Screening entails a preliminary rapid assessment for drugs of abuse. While Screening is an economical approach to discount drug use in most samples, a successful screening necessitates confirmation for legal purposes. Samples with positive presumptive results in Screening require further confirmation.

If the Screening stage reveals a presumption of positivity, additional hair is extracted from the primary sample for the Extraction phase. Here, drugs are extracted from hair in significantly lower concentrations than in alternate methods (such as urine or oral fluid), accounting for the high complexity of hair drug testing.

The confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS technology. All samples with presumptive positives undergo washing before confirmation as needed. The entire procedure from Accessioning to Confirmation undergoes scrutiny through the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing identifies drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Low likelihood of evasion: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Offers historical insight: It allows tracking drug usage patterns over time, rather than recent usage alone.

Limitations:

• Lacks detection of immediate use: Drugs become detectable in hair roughly 5-7 days post-use.
• Expense: Hair drug tests are typically pricier than other testing methods.
• Result variability: Individual factors like hair color and growth rate may influence drug metabolite concentrations in the hair.

Note: Though called "hair follicle tests," the analysis targets the hair strand, not the follicle beneath the skin.

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.
