Hair Follicle Drug Testing - Norge, OK

What it is, How it works

Hair analysis is becoming recognized as an effective means for detecting alcohol and drug consumption. Hair archives a prolonged record of alcohol and other substances by fixing biomarkers within the structure of the hair shaft as it grows. When collected from near the scalp, hair offers a detection window of up to about 90 days for alcohol and other substances. It’s straightforward to collect, moderately resistant to tampering, and simple to transport.

A 1.5-inch hair sample comprising approximately 200 strands (approximately the diameter of a #2 pencil) nearest to the scalp offers 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional panels, and/or testing beyond ten panels, a sample of 150mg is advised. We suggest verifying the weight of the sample using a jeweler’s scale. If scalp hair is unavailable, the equivalent amount of body hair can be collected. “Head hair” refers specifically to scalp hair only, whereas “body hair” encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The four primary stages involved in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial entry of a sample into a lab’s system. This process verifies whether the sample was sealed and transported correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any remaining data input not covered by an electronic chain of custody system.

Screening involves a preliminary inspection for drug abuse. While Screening is an economical means to determine drug use in most samples, a positive result necessitates confirmation to be suitable for court. Any samples testing presumptively positive during Screening require a follow-up confirmation.

If a sample tests presumptively positive during Screening, additional hair is taken from the initial specimen for Extraction preparation. During this stage, drugs are retrieved from hair at a substantially lower concentration compared to other methods (such as urine or oral fluid), which makes hair drug screening the most intricate method to conduct.

Confirmation of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as required. The comprehensive laboratory procedure, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug usage for up to 90 days, unlike urine tests, which have shorter detection windows.
• Minimal chance of tampering: Altering a hair drug test is quite difficult, thus yielding more reliable results.
• Historical insight: It shows a pattern of drug usage over time, not just recent consumption.

Limitations:

• Inability to identify recent use: Drugs take about 5-7 days to be detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to alternate testing methods.
• Result variations: Variations such as hair color and individual hair growth rates can impact drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," the analysis examines the hair shaft instead of the hair follicle below 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. 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.
