Hair Follicle Drug Testing - Trout, WV

What it is, How it works

Hair testing is increasingly recognized as a significant method for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and various drugs by embedding biomarkers within the fibers of the extending hair strand. When obtained near the scalp, hair can reveal up to an approximately three-month detection period for alcohol and other substances. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.

An ideal sample for evaluation and confirmation consists of a 1.5-inch segment of roughly 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp, offering 100mg of hair. For EtG, additional tests, and/or examinations beyond 10 panels, 150mg of the sample is advised. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair can be gathered. When discussing head hair, it refers exclusively to scalp hair. Body hair denotes all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four main phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial handling of a sample within a lab’s framework. This comprises verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not furnished by an electronic chain of custody system.

Screening provides an initial rapid assessment for substance abuse. While Screening is a cost-efficient method to discount drug usage for most samples, a positive screen must be validated for legal admissibility. Any samples with a presumptively positive Screening require a further confirmation.

If Screening suggests a positive result, more hair is taken from the original specimen for Extraction preparation. During this step, drugs are extracted from hair at a much lower concentration than in other techniques (e.g., urine or oral fluid), illustrating the complexity of hair drug screening procedures.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is washed prior to confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, compared to urine tests, which have a shorter detection timeframe.
• Challenging to falsify: It is exceedingly tough to deceive a hair drug test, enhancing result accuracy.
• Supplies historical insight: It can show a usage pattern over time, instead of just recent use.

Limitations:

• Inability to detect immediate use: It takes around 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests are typically more costly than alternative testing methods.
• Result variability: Elements like hair color and individual hair growth differences can alter the drug metabolite concentration in the hair.

Note: Though often termed "hair follicle tests", the analysis targets the hair strand, 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.
