Hair Follicle Drug Testing - Nile, WA

What it is, How it works

Hair analysis has emerged as an effective method for identifying the use of drugs and alcohol. Hair captures a comprehensive history of substances by embedding biomarkers within the hair's structure. When samples are taken near the scalp, hair can reveal a detection period of up to three months for substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch section of approximately 200 hairs (similar to the width of a #2 pencil) closest to the scalp provides around 100mg, which is optimal for both screening and confirmation. For comprehensive tests such as EtG or those exceeding 10 panels, 150mg is advisable. It's suggested to weigh the hair on a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair can be gathered. By "head hair," we mean only scalp hair. "Body hair" refers to all other types like facial and axillary hair.

Process Overview

The process for analyzing drug test samples in a lab involves four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with prepping a sample for entry into the lab’s systems. This involves checking that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic chain of custody.

Screening involves a preliminary inspection for potential drug abuse. While it's budget-friendly and rules out drug use for most samples, any positive findings in Screening must undergo further confirmation before being deemed valid for legal proceedings. Samples appearing positive initially in Screening need additional verification.

If a sample tests positive in the Screening phase, extra hair is extracted from the original sample for the Extraction phase. Here, substances are isolated from the hair at lower concentrations than with other testing types (like urine or saliva), making hair analysis one of the most intricate methods.

Confirmed positive screening results are verified using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Potential positives undergo washing before confirming, if necessary. The entire process from Accessioning to Confirmation is conducted under oversight by both CAP (College of American Pathologists) Hair criteria and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can find drug usage up to 90 days, unlike urine tests, which detect for a shorter time frame.
• Hard to falsify: It's very challenging to deceive a hair drug test, enhancing result accuracy.
• Shows historical patterns: It illustrates a pattern of drug consumption over a span of time, not merely recent usage.

Limitations:

• Cannot determine very recent use: Drugs typically become detectable in hair between 5-7 days.
• Higher cost: Hair drug tests generally incur more expenses compared to other types of testing.
• Result variability: Factors like hair color and individual hair growth differences can impact the drug metabolites' concentration in hair.

Note: Despite being referred to as "hair follicle tests," the test actually examines the hair strands, not the follicle under the skin.

Why Hair Follicle Testing Beats Urine Testing

In Nile, WA, hair follicle testing outperforms traditional urine testing by offering superior detection accuracy.

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.
