Hair Follicle Drug Testing - La Vale, MD

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying the use of drugs and alcohol. By embedding biomarkers within the strands, hair offers a longer-term record of substance use. When sourced directly from the scalp, hair can reveal a drug and alcohol history spanning up to three months. It’s straightforward to gather, relatively resistant to tampering, and simple to transport.

Gathering a 1.5-inch section of roughly 200 hairs (comparable to a #2 pencil) from the scalp provides 100mg of hair, which is ideal for both initial and confirmatory screenings. For EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler's scale to confirm the weight of the specimen. If scalp hair isn’t available, a comparable amount of body hair can be collected. When we mention head hair, we're referring specifically to scalp hair. Body hair encompasses all other hair types (such as facial, underarm, etc.).

Process Overview

The laboratory analysis of a drug test employs four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing of a sample into the laboratory system. This stage ensures that the sample is properly sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and completes any further data entry not provided by an electronic chain of custody.

Screening entails an initial rapid check for substances of abuse. While Screening is a budget-friendly method for ruling out drug use in most samples, a confirmed positive result is required for legal admissibility. Any samples that are possibly positive in Screening require further confirmation.

For specimens showing potential positivity in Screening, additional hair is extracted from the original sample for the Extraction phase. In this phase, drug levels are extracted from hair at lower concentrations than in other testing methods (e.g., urine or saliva), which is why hair drug screening is often more complex to conduct.

Confirmation of any positive results from Screening is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are washed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is audited under both the College of American Pathologists (CAP) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug testing can detect drug use extending up to 90 days, outlasting urine tests with a more brief detection period.
• Resistance to manipulation: Cheating a hair drug test is notably challenging, ensuring more reliable results.
• Shows historical consumption: It can demonstrate usage patterns over time rather than recent usage alone.

Limitations:

• Inability to detect recent usage: Drugs typically require about 5-7 days to become traceable in hair.
• Expense: Hair drug testing tends to cost more compared to other testing procedures.
• Result variability: Differences such as hair color and individual growth rates can impact drug metabolite concentrations in hair.

Note: Despite often being referred to as "hair follicle tests," the analysis focuses on the strand of hair rather than 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.
