Hair Follicle Drug Testing - Johnston, IA

What it is, How it works

Hair analysis is acknowledged as an effective method for identifying drug and alcohol consumption. It offers an extended record of substance use by capturing biomarkers within the strands of growing hair. When the hair is sampled near the scalp, it can detect substances for a period of up to three months. Collecting hair is uncomplicated, challenging to tamper with, and straightforward to send.

A sample measuring 1.5 inches and consisting of around 200 hair strands (similar in size to a #2 pencil lead) from the scalp equates to about 100mg of hair, which is the optimal quantity for testing and verification. For EtG, add-ons, and tests beyond 10 panels, 150mg of hair is advisable. Using a jeweler’s scale to measure the specimen is recommended. Should scalp hair be unavailable, an equivalent amount of body hair can be utilized. References to head hair imply scalp hair specifically. Body hair includes all other types like facial or axillary hair.

Process Overview

The drug testing laboratory workflow consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed within the lab's framework. This stage involves confirming the sample is properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from the electronic chain of custody.

Screening provides an initial rapid assessment for drug presence. While it's an economical means to negate drug use in most samples, a conclusive positive requires confirmation for legal acceptability. Any potentially positive outcomes in Screening necessitate further confirmation.

In cases of potential positivity in Screening, additional hair from the original sample is used for Extraction. Here, drugs are isolated from the hair at lower concentrations than other methods such as urine or oral fluid tests, demonstrating why hair drug testing poses significant challenges.

Confirmation of positive results involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation washing is applied as necessary to any preliminary positive samples. The entire lab procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection range: Hair tests can reveal drug use history up to 90 days, surpassing the shorter span of urine testing.
• Resistance to manipulation: Hair drug tests are tough to deceive, enhancing result credibility.
• Provides usage patterns: It exhibits patterns of drug utilization over time, rather than only recent intake.

Limitations:

• Latency on recent detection: Drugs become discernible in hair approximately after 5-7 days.
• Expense: Typically, hair drug testing incurs a higher cost than other drug testing approaches.
• Result variability: Variables such as hair color and growth rate can influence drug metabolite levels in hair.

Note: Though often called "hair follicle tests", the procedure evaluates the hair strand, not the underlying follicle.

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.
