Hair Follicle Drug Testing - Torboy, WA

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a historical archive for substances by capturing biomarkers in the strands as they grow. When taken from near the scalp, hair can reveal drug and alcohol intake within a timeframe of up to three months. Collection is straightforward, tampering is challenging, and transportation is convenient.

A 1.5-inch snippet of approximately 200 hair strands (comparable to a #2 pencil in size) taken nearest to the scalp amounts to 100mg, which is the preferred quantity for testing and validation. For tests such as EtG, additional screenings, or those exceeding 10 panels, 150mg is advisable. It's important to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. When discussing head hair, it's solely in relation to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is integrated into a laboratory system. The process ensures the sample was sealed and transported correctly, assigns a unique Laboratory Accessioning Number (LAN), and completes any necessary extra data entry not covered by an electronic tracking system.

Screening is a preliminary inspection for substance misuse. Although Screening is an economical method to exclude drug usage for most samples, a positive result must be verified to hold up in legal proceedings. Any samples with a presumptive positive result from Screening must undergo further confirmation.

If a sample shows a presumptive positive result in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at substantially lower levels than in other methods (e.g., urine or oral fluid), making hair drug analysis the most complex methodology to conduct.

Validation of any positive result from Screening is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive result are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair specifications and the accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: It is exceedingly difficult to falsify a hair drug test, making its findings more reliable.
• Tracks past use: It can outline a pattern of substance use over time, not just recent activities.

Limitations:

• Inability to identify recent use: It requires approximately 5-7 days for substances to become noticeable in hair.
• Expense: Hair drug tests typically cost more than alternative drug testing techniques.
• Result inconsistencies: Elements like hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: Though commonly referred to as "hair follicle tests", the analysis itself targets the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

For those in Torboy, WA, hair follicle testing surpasses urine tests in several ways. They offer a longer detection period, increasing the accuracy and dependability of results.

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.
