Hair Follicle Drug Testing - Montgomery Village, MD

What it is, How it works

The utilization of hair testing has emerged as an effective method for uncovering alcohol and drug consumption. Hair can encapsulate biomarkers within its strands, providing a prolonged timeline of drug and alcohol presence. When gathered near the scalp, hair offers an approximate detection span of three months for substances. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.

To obtain an optimal hair sample for testing, a 1.5-inch segment containing around 200 strands (comparable to a #2 pencil's thickness) nearest the scalp is ideal, producing 100mg of hair. For specific tests like EtG add-ons or those exceeding 10 panels, a 150mg specimen is suggested. Using a jeweler’s scale for weighing is advisable. If scalp hair is unattainable, an equivalent portion of body hair can be utilized. The reference to head hair strictly means scalp hair, whereas body hair encompasses other types (such as facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the lab's system, ensuring it was correctly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not managed by an electronic chain of custody method.

Screening presents an initial rapid assessment for controlled substances. Though Screening is an economical approach to exclude substance use in most samples, a positive screen demands confirmation to stand as court evidence. Samples with positive presumption in Screening necessitate further verification.

Should a sample return a presumptively positive result during Screening, additional hair is extracted from the initial sample and prepped for Extraction. This phase involves retrieving drugs from hair at notably lower concentrations compared to alternative methods (e.g., urine or saliva testing), hence, hair drug screening is recognized as a complex process.

Positive screening results are confirmed using techniques like GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo a cleansing step before confirmation if necessary. The entire laboratory chain from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug evaluations can identify substance use up to 90 days, longer than the within urine tests.
• Challenging to manipulate: Hair drug tests are significantly tamper-resistant, ensuring accuracy in outcomes.
• Delivers usage records: It delineates a user's substance pattern over a timeline, not merely recent consumption.

Limitations:

• Incapable of identifying recent ingestion: It requires 5-7 days for drugs to become evident within hair strands.
• Expense: Hair drug tests bear a higher cost than other testing alternatives.
• Variance in findings: Variables like hair pigmentation and individual growth rates can influence the metabolite concentration recorded in hair.

Note: Though often termed as "hair follicle tests", the test examines the hair strand itself, 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.
