Hair Follicle Drug Testing - Mcalister, NM

What it is, How it works

Hair analysis has emerged as a potent resource for identifying substance and alcohol consumption. Hair encapsulates markers of alcohol and drugs within the fibers of its growing strands, offering an extended timeline of substance use. When collected near the root, hair can reveal substance use data covering an approximate span of three months for both alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and easily transportable.

An ideal screening and confirmation sample consists of a 1.5-inch segment comprising roughly 200 hair strands (around the size of a #2 pencil) adjacent to the scalp, which equates to 100mg. To expand tests to EtG, additional substances, and/or panels beyond ten, a 150mg hair sample is suggested. A jeweler’s scale is optimal for weighing the sample. In the event scalp hair is not available, an equivalent amount of body hair is acceptable. References to head hair denote only scalp hair, whereas body hair includes all other varieties (e.g., facial, axillary).

Process Overview

The laboratory procedure for processing drug test outcomes encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Initial Accessioning translates to the entry of a sample into a lab’s system, certifying its seal and correct shipment, allotting a random LAN (Laboratory Accessioning Number), and concluding any extra data entry absent from an electronic chain of custody system.

Screening represents a primary swift assessment for substances of abuse. While cost-effective in eliminating drug use in many instances, a screen producing a positive result necessitates validation to be court-admissible. Any samples flagged as presumptive positives at the Screening phase mandate further confirmation.

Subsequent to a presumptive positive Screening result, additional hair is extracted from the initial sample to be prepared for Extraction. In this level, hair-based drug extraction entails reduced concentration compared to alternative methodologies (such as urine or oral fluid), thus making hair drug screening a more intricate process.

Any positive results in Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Necessary washing of presumptive positive samples precedes confirmation. The entire lab process from Accessioning to Confirmation adheres to scrutiny under both the CAP (College of American Pathologists) Hair criteria and is aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can track drug use for a span of up to 90 days, contrasting with the relatively shorter detection periods of urine tests.
• Resistance to manipulation: Cheating a hair drug test is notably challenging, increasing the likelihood of accurate results.
• Historical insight: It offers insights into drug use trends over extended durations, rather than simply chronicling recent usage.

Limitations:

• Incapacity to identify recent consumption: Drugs become detectable in hair only after around 5-7 days.
• Expense: Hair drug analyses typically entail a greater financial cost compared to other testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations within hair.

Note: Although sometimes termed "hair follicle tests", the actual analysis pertains to the hair strand instead of 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.
