Hair Follicle Drug Testing - Largo, MD

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol use. By encapsulating biomarkers, hair offers a comprehensive view of alcohol and drug consumption. When taken from the scalp, hair can reveal substance use for roughly three months. It is straightforward to gather, challenging to tamper with, and simple to transport.

A 1.5-inch-long sample, roughly the thickness of a #2 pencil (about 200 strands), will yield 100mg of hair, making it ideal for testing. For EtG, additional tests, or analyses exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale for accuracy. If scalp hair isn’t available, body hair can be used as an alternative. When we refer to head hair, we specifically mean scalp hair, while body hair encompasses all other types (e.g., facial, underarm).

Process Overview

The four fundamental stages in processing a drug test sample in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the entry point for sample processing in the lab’s system, ensuring samples are sealed and shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and conducting any additional data entry not managed by an electronic chain of custody.

Screening provides an initial check for drugs of abuse. While it’s a cost-effective method to eliminate drug usage in many cases, a positive Screening result must be confirmed for legal admissibility. Presumptively positive samples require secondary confirmation.

If a Screening result is positive, additional hair is sourced from the initial sample for Extraction. Drugs are removed from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting hair drug testing as a complex methodology.

Confirmation of positive Screening results is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The entire process, from Accessioning to Confirmation, aligns with CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 credentials.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days, unlike the shorter timeframe seen in urine tests.
• Resistant to tampering: It is difficult to manipulate a hair drug test, ensuring more reliable results.
• Historic use patterns: Offers insights into drug usage patterns over time, rather than just recent usage.

Limitations:

• Incapable of detecting recent use: Drugs take roughly 5-7 days to become apparent in hair.
• Expense: Hair drug testing typically costs more than other testing methods.
• Result variations: Factors like hair color and individual growth rates can influence the presence of drug metabolites in hair.

Note: Often termed as "hair follicle tests", these tests actually analyze 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.
