Hair Follicle Drug Testing - Village Saint George, LA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol usage. Hair captures a prolonged record of alcohol and other drug consumption by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can offer a detection timeframe for alcohol and drugs up to around three months. Hair samples are easy to gather, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment comprising roughly 200 strands of hair (equivalent to a #2 pencil in size) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG additions, and/or tests that exceed 10 panels, 150mg of the sample is advised. It's suggested to measure the specimen using a jeweler's scale. If scalp hair isn’t available, a similar quantity of body hair can be collected. References to head hair specifically mean scalp hair only. Body hair encompasses all other types (e.g., facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially integrated into the laboratory's system. This process includes confirming the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.

Screening is an initial rapid assessment for drug abuse. Screening offers a cost-effective means to eliminate drug presence in most cases, but any positive screen must be verified to be valid in legal proceedings. Samples that test presumptively positive require further confirmation.

If a sample tests presumptively positive at the Screening stage, additional hair is taken from the initial sample and prepared for Extraction. This step involves drawing drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), explaining why hair drug screening is among the most challenging techniques to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug use up to 90 days, unlike urine tests which have a shorter detection time.
• Challenging to falsify: It is very difficult to falsify a hair drug test, leading to more accurate results.
• Delivers historical insights: It can reveal drug usage patterns over time, not just recent activity.

Limitations:

• Inability to detect immediate use: Drugs become identifiable in hair approximately 5-7 days after use.
• Expense: Hair drug tests generally cost more than other methods of drug testing.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly referred to as "hair follicle tests," the analysis is of the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
