Hair Follicle Drug Testing - Stevensville, MD

What it is, How it works

Hair assessments have emerged as a robust mechanism for identifying the consumption of substances like drugs and alcohol. The strands of hair encapsulate markers of substances over time, providing a historical record. When collected from near the scalp, hair delivers an insightful detection timeframe of up to roughly 90 days for alcohol and drugs. The procedure for collecting hair samples is straightforward, somewhat resistant to tampering, and uncomplicated for shipping.

A 1.5-inch strand of approximately 200 hairs (comparable to the width of a #2 pencil) close to the scalp offers around 100mg of hair, which is the ideal quantity for both screening and verification. For evaluations like EtG add-ons or tests exceeding 10 panels, a sample of 150mg is advised. We suggest measuring the specimen with a jeweler’s scale. In instances where scalp hair is absent, an equivalent quantity of body hair may be procured. The term "head hair" specifically pertains to scalp hair, while "body hair" encompasses all other types of hair (such as facial or axillary).

Procedure Overview

The principal stages involved in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial processing within a lab’s system. This phase includes confirming that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and inputting any additional data that's not available through an electronic chain of custody system.

Screening constitutes an initial swift inspection for drug abuse. Although Screening is a cost-effective strategy to negate drug use in the majority of samples, any positive identifications require confirmation to be viable in legal contexts. Samples flagged as presumptively positive in Screening necessitate further confirmation.

Upon a presumptive positive result in the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are sourced from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug analysis one of the most challenging techniques to conduct.

Any positive result in screening is validated via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples that test positive are washed as needed. The comprehensive lab process from Accessioning to Confirmation undergoes review adhering to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Benefits of hair drug assessments:

• Extended detection period: Hair drug evaluations can determine drug use up to 90 days, whereas urine tests offer a shorter detection window.
• Resistance to deception: Manipulating the results of a hair drug test is exceedingly challenging, enhancing result precision.
• Illustrates historical usage: It reveals a usage pattern over time, rather than just recent drug use.

Constraints:

• Inability to detect recent consumption: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug evaluations tend to be pricier than other testing methods.
• Variability in outcomes: Elements such as hair color and personal growth differences can alter the concentration of drug metabolites in the hair.

Note: Although frequently termed as "hair follicle tests", the analysis actually examines the hair shaft, 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.
