Hair Follicle Drug Testing - Charlotte Hall, MD

What it is, How it works

Hair testing stands out as a robust method for identifying drug and alcohol consumption. The strands of hair capture biomolecules as they grow, offering an extended overview of substance use when sampled near the scalp, potentially detecting alcohol and drugs over a span of up to three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch hair sample, roughly comprising 200 strands (comparable to the thickness of a #2 pencil), yields around 100mg, ideal for screening and subsequent confirmation. For EtG, additional tests, or panels exceeding ten, a 150mg sample is advisable. Utilizing a jeweler's scale for weighing is recommended. In the absence of scalp hair, a comparable quantity of body hair can be used. It's important to note that 'head hair' specifically refers to scalp hair, while 'body hair' encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory steps for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the stage where a sample is initially processed into a lab's system. This involves checking that the sample was adequately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent in an electronic chain of custody system.

Screening serves as a preliminary assessment for detecting drug abuse. While it is a cost-saving method for dismissing drug use in most samples, a positive screening result requires confirmation for legal acceptance. Samples that test presumptively positive during Screening need a secondary validation.

In cases where Screening identifies a sample as presumptively positive, further sample extraction is undertaken, obtaining more hair for the Extraction phase. Here, drugs are extracted from hair at concentrations much lower than other methods like urine or oral fluid, which is why hair drug screening presents a challenging methodology.

Should there be a need for Confirmation of positive screening outcomes, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Presumptive positives undergo washing before confirmation, as necessary. The complete laboratory procedure, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection duration: Hair tests can spot drug use for as long as 90 days, unlike urine tests with a shorter detection span.
• Hard to evade: Hair drug tests are notably difficult to cheat, enhancing result reliability.
• Tracks past behavior: These tests reveal a history of drug use over time, rather than just recent consumption.

Limitations:

• Delayed detection: Drugs become detectable in hair within approximately 5-7 days.
• Expense: Hair drug testing typically incurs higher costs compared to other testing approaches.
• Result variability: Elements such as hair color and individual hair growth patterns can influence drug metabolite levels in hair.

Note: Often called "hair follicle tests," the examination assesses the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Charlotte Hall, MD, hair testing stands out for its superior detection 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.
