Hair Follicle Drug Testing - Terrytown, LA

What it is, How it works

Hair analysis is now recognized as a robust means of identifying drug and alcohol consumption. The hair holds a comprehensive record of alcohol and narcotics through the entrapment of biomarkers within the hair shaft. When gathered near the scalp, hair offers a detection span of up to about three months for alcohol and narcotics. Collection of hair is straightforward, somewhat challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, comprising approximately 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp, yields 100mg, the optimal quantity for both screening and confirmation. It's advisable to use 150mg for EtG, supplemental, and/or tests surpassing 10 panels. Utilizing a jeweler's scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent amount of body hair can be sourced. 'Head hair' specifically relates to scalp hair, while 'body hair' encompasses all other types (such as facial and axillary hair).

Process Overview

The lab processing of a drug test result involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about the initial sample processing into the lab's system. This incorporates checking that the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing additional data entry not furnished by an electronic chain of custody system.

Screening delivers a prompt assessment for substances of abuse. While Screening is an economical strategy to filter out drug use in most samples, a positive result requires confirmation to be defensible in a legal setting. Any samples flagged as potentially positive during Screening necessitate a secondary confirmation.

Samples flagged as potentially positive during Screening need additional hair extracted from the original sample and prepared for Extraction. In this phase, the drugs are extracted from hair at remarkably lower concentrations compared to other methodologies (e.g., urine or oral fluid), hence making hair drug testing the most challenging methodology to execute.

Any Screening positive is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing as necessary before confirmation. The complete lab workflow from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair category and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug consumption for up to 90 days, while urine tests have a briefer detection window.
• Challenge to evade: Subverting a hair drug test is remarkably challenging, thereby enhancing result accuracy.
• Historical insights: These tests provide a view of drug usage trends over time rather than just recent usage.

Limitations:

• Inability to identify recent usage: Detecting drugs in hair typically takes 5-7 days.
• Expense: Hair drug tests tend to be pricier than other drug testing methods.
• Result variations: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Often termed as "hair follicle tests," the analysis focuses on the hair shaft, 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.
