Hair Follicle Drug Testing - National Harbor, MD

What it is, How it works

Utilizing hair testing has increasingly become recognized as a significant method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the emerging hair. When obtained near the scalp, hair can deliver a detection timeline for alcohol and other drugs up to about 3 months. Hair collection is straightforward, relatively tamper-proof, and convenient for shipping.

A sample of hair measuring 1.5 inches, comprising approximately 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the optimal quantity for screening and verification. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair can be utilized. Head hair refers exclusively to scalp hair, while body hair encompasses all other kinds (facial, axillary, etc.).

Process Overview

The testing procedure in the laboratory for a drug test result includes four core phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the lab’s system. This phase involves checking that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.

Screening is a preliminary inspection for drugs of misuse. Though Screening serves as an economical approach to dismiss drug usage in most samples, any positive outcome from a screening necessitates confirmation to be recognized in legal proceedings. Samples that result in a tentative positive in Screening call for further confirmation.

In the event a sample tests tentatively positive during Screening, additional hair is gathered from the primary sample and set up for Extraction. In this phase, drugs are extracted from hair at concentrations much lower than other methods (such as urine or saliva), which makes hair drug testing the most challenging method to conduct.

Any positive result in Screening is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All provisional positive samples undergo washing prior to confirmation when necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards of accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug screenings can identify drug usage for up to 90 days, surpassing urine tests, which have a more limited detection window.
• Hard to manipulate: Cheating a hair drug test is substantially tough, enhancing result accuracy.
• Reveals usage patterns: It offers an overview of drug consumption over time, not merely recent usage.

Limitations:

• Unable to detect recent consumption: Detection in hair commences about 5-7 days after drug use.
• Expense: Generally, hair drug tests incur higher costs compared to other testing methodologies.
• Inconsistent results: Aspects like hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although occasionally alluded to as "hair follicle tests", the examination evaluates the hair strand, not the follicle residing below 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.
