Hair Follicle Drug Testing - Elizabethtown, NC

What it is, How it works

Hair testing is now recognized as an effective means for identifying misuse of drugs and alcohol. The strands trap biological markers within their fibers, delivering a comprehensive historical record of substance use. Collected near the scalp, hair analyses offer a detection reach of around 90 days for drugs and alcohol. The specimen is straightforward to gather, less likely to be tampered with, and uncomplicated to transport.

An optimal 1.5-inch hair sample, amounting to roughly 200 strands (similar in size to a #2 pencil), yields about 100mg, appropriate for both screening and corroborating results. For tests over 10 panels, EtG, or additional components, 150mg is advised. It's recommended to use a jeweler's scale for weighing the hair. If scalp hair is not available, an equal quantity from body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).

A Glance at the Procedure

The core phases in lab processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into the lab’s system. This confirms that the sample is correctly sealed and sent, attaches a random LAN (Laboratory Accessioning Number), and finalizes any missing data entries not included by an electronic chain of custody system.

Screening provides a preliminary scan for drug abuse. While it's a cost-saving approach to eliminate drug use for most specimens, a positive outcome needs verification for legal standards. Presumptively positive screenings necessitate further corroboration.

When a specimen tests presumptive positive in Screening, more hair is extracted from the primary sample for Extraction. This step isolates drugs from the hair at notably lower concentrations than urine or oral fluid methods, highlighting the complexity in performing hair drug analysis.

Confirmation for positive screenings occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, presumptive samples are cleansed as required. The complete lab procedure, from Accessioning to Confirmation, falls under the review of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Hair drug screening benefits:

• Extended detection: Hair tests trace drug use over 90 days, unlike urine tests with shorter durations.
• Hard to falsify: Cheating on hair drug tests is challenging, ensuring more reliable results.
• Offers use trends: It shows drug use patterns over time, rather than merely recent consumption.

Drawbacks:

• No detection of recent use: Drugs become visible in hair only about 5-7 days post-consumption.
• Expenses: Hair analysis tends to cost more compared to other drug testing methods.
• Result variability: Factors like hair color and personal hair growth rates may influence metabolite levels in hair.

Note: While commonly termed "hair follicle tests," the procedure actually examines the hair strand, not the follicle underneath 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.
