Hair Follicle Drug Testing - Minters Chapel, TX

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol usage. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When clipped close to the scalp, it can reveal up to a 3-month detection period for substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch snip comprising about 200 hairs (roughly the size of a #2 pencil) near the scalp yields 100mg, which is the perfect quantity for analysis and validation. For EtG tests, additional panels above 10, or special assays, 150mg is advisable. It's best to weigh samples on a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair may be secured. When we talk about head hair, it specifically refers to scalp hair. Body hair encompasses other types (like facial, axillary, etc.).

Process Overview

The processing of drug test results in a lab involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory step of inserting a sample into the laboratory's system. This phase includes checking if the specimen was sealed and delivered accurately, assigning a unique LAN (Laboratory Accessioning Number), and entering extra data that isn’t available via an electronic chain of custody system.

Screening is the primary stage for detecting drugs. Although Screening is a budget-friendly approach to exclude substance use in most samples, any positive finding needs confirmation to qualify in legal proceedings. Samples with presumptive positives during Screening necessitate further validation.

When a sample hints positive in Screening, additional hair is taken from the original specimen for Extraction. In this phase, drugs are extracted from hair at much lower concentrations compared to other techniques (like urine or saliva), highlighting why hair drug testing is challenging.

All positive results in the Screening phase are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples identified as presumptive positives undergo washing for confirmation when required. The whole procedure, from Accessioning to Confirmation, falls under both the oversight of the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can indicate drug use for up to 90 days, in contrast to urine tests, which have a shorter detection timeframe.
• Hard to manipulate: It's notoriously difficult to deceive a hair drug test, thus improving result fidelity.
• Shows historical use: It reflects a trend of substance use over time, not just recent activity.

Limitations:

• Recent use not tracked: It takes about 5-7 days for drugs to appear in hair samples.
• Expense: Hair drug assessments are mostly pricier than alternate testing options.
• Result discrepancies: Hair color and personal hair growth rates may affect drug metabolite levels in hair.

Note: Typically labeled as "hair follicle tests", the examination relies on the hair strand instead of the scalp-bound follicle

Why Hair Follicle Testing Beats Urine Testing

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.
