Hair Follicle Drug Testing - Elk Neck, MD

What it is, How it works

Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. The hair strand retains a historical record of alcohol and drugs by embedding biomarkers within its fibers as it grows. When gathered near the head, hair can reveal alcohol and drug use over an approximate 3-month span. Collecting hair is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch section of around 200 hair strands (about the thickness of a #2 pencil) near the scalp can provide 100mg of hair, optimal for both screening and confirmation. For EtG, extra tests, and/or panels beyond 10, a 150mg sample is advised. We suggest measuring the sample with a jeweler's scale. Substitute hair from the body can be used if scalp hair is not available. When specifying head hair, it refers exclusively to scalp hair. All other types (facial, axillary, etc.) fall under body hair.

Process Overview

The drug test result processing in the laboratory involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes inputting a sample into a lab's system initially. This step checks if the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and enters any further data not handled by an electronic chain of custody.

Screening provides a preliminary rapid assessment for substance abuse. Although it’s a cost-efficient method to eliminate drug use for most samples, a positive screening needs validation to be considered in legal settings. Presumptive positive samples in Screening require further confirmation.

If a Screening sample shows a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, substances are removed from the hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluids), highlighting the complexity of performing hair drug screening.

Positive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation, if necessary. The complete process, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation alongside ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for up to 90 days, unlike urine tests which have a shorter window.
• Challenge to deceive: It is quite challenging to manipulate a hair drug test, ensuring more precise outcomes.
• Provides usage trends: It records a pattern of drug consumption over time, not merely recent use.

Limitations:

• Inability to identify recent consumption: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair drug testing often costs more than alternative testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although termed as "hair follicle tests," the procedure evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The benefits of hair follicle testing over urine tests are evident in Elk Neck, MD. Unlike urine tests, hair testing offers superior accuracy and reliability.

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.
