Hair Follicle Drug Testing - Walnut Grove, MS

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol use. Hair serves as a long-term record for alcohol and various drugs by capturing biomarkers within the hair strand fibers as they grow. When obtained near the scalp, hair can reveal up to a 3-month detection period for substances and alcohol. Hair collection is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch segment comprising roughly 200 hair strands (approximately the thickness of a #2 pencil) taken from the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, supplementary tests, or panels exceeding 10, a specimen of 150mg is advised. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair can't be obtained, an equivalent amount of body hair can be used. References to head hair solely imply scalp hair, while body hair covers all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of drug test results consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where the sample is incorporated into the laboratory system. This step entails confirming proper sealing and dispatch of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody system.

Screening involves an initial swift evaluation for drug abuse. Although an economical method to exclude drug usage for most samples, a positive screening result necessitates confirmation for legal admissibility. Presumptive positives from Screening require further verification.

In instances of presumptive positivity during Screening, additional hair is utilized from the original specimen for Extraction. This step involves extracting drugs from hair at a considerably lower concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening notably challenging.

Any positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a preliminary wash before confirmation if needed. The entire laboratory process from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can identify drug use for up to 90 days, unlike urine tests which offer a briefer detection timeline.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, ensuring more reliable results.
• Reveals historical patterns: Hair tests show trends in drug usage over time, beyond recent consumption.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Higher expense: Hair drug tests tend to be costlier than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests," the analysis pertains to the hair strand and 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.
