Hair Follicle Drug Testing - Mcclure, IL

What it is, How it works

Hair analysis has become recognized as an effective means for detecting the consumption of drugs and alcohol. By capturing biomarkers within the strands of growing hair, it offers a comprehensive history of alcohol and drug use. Hair samples taken near the scalp can reveal drug and alcohol usage extending back around three months. Collecting hair is straightforward, relatively tamper-resistant, and easily transportable.

A sample measuring 1.5 inches, containing approximately 200 hair strands (comparable to the thickness of a #2 pencil), can yield 100mg, the preferred quantity for both screening and verification. For EtG, additional panels, or when testing beyond 10 panels, a 150mg sample is advised. Use a jeweler's scale to measure the specimen weight accurately. If scalp hair isn't available, an equivalent quantity of body hair can be procured. "Head hair" specifically refers to scalp hair, while "body hair" pertains to all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial step of integrating a specimen into the lab's system, ensuring the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any required data entry that isn't handled by an electronic chain of custody system.

Screening performs a preliminary check for illicit drugs. Although Screening is a cost-saving measure to exclude drug use in most specimens, any positive results need subsequent confirmation for legal validity. Presumptive positives from Screening necessitate further confirmation.

When a specimen tests presumptively positive at the Screening stage, additional hair from the initial sample is prepared for Extraction. In Extraction, drugs are isolated from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Positive screening results are confirmed via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The full laboratory process from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug analysis can identify drug use for approximately 90 days, unlike urine tests, which have a shorter detection timeframe.
• Difficulty to cheat: Cheating a hair drug test is challenging, thereby enhancing result accuracy.
• Provides historical data: It can chart a drug use pattern over time, offering more than just a snapshot of recent consumption.

Limitations:

• Cannot detect recent use: Detectable drug traces appear in hair approximately 5-7 days after use.
• Cost: Hair drug analyses are generally costlier than other drug testing methods.
• Variations in results: Hair color and personal hair growth differences can alter drug metabolite concentrations in hair samples.

Note: Although commonly called "hair follicle tests", this test assesses the hair strand itself, not the follicle beneath 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.
