Hair Follicle Drug Testing - Willows, MD

What it is, How it works

The perception of hair testing has evolved into seeing it as a robust method for detecting drug and alcohol consumption. Hair strands offer an extensive timeline of drug and alcohol use by capturing biomarkers within the fiber of the hair as it grows. Collecting hair close to the scalp allows for a detection time frame of roughly 3 months for drugs and alcohol. Hair is straightforward to collect, relatively resistant to tampering, and convenient to transport.

A sample comprising 1.5 inches of roughly 200 strands of hair (the equivalent of a #2 pencil) nearer to the scalp provides 100mg of hair, which is ideal for both screening and verification. For EtG, additions, and/or tests exceeding 10 panels, a 150mg specimen is advised. We suggest weighing the sample on a jeweler’s scale. If scalp hair cannot be sourced, an equivalent amount of body hair is acceptable. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The core steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introduction of a sample into the lab’s workflow. This step ensures the sample was sealed and shipped with care, assigns a random LAN (Laboratory Accessioning Number), and manages additional data entries absent from an electronic chain of custody protocol.

Screening acts as a primary evaluation for signs of drug misuse. Although it offers a cost-efficient approach to exclude substance use in most samples, results that test positive during Screening require further confirmation to hold validity in legal proceedings. Samples with presumptive positive results in Screening need secondary confirmation.

Should a sample test presumptively positive in Screening, more hair is extracted from the original specimen for Preparation for Extraction. In this phase, drugs are drawn out from hair at significantly lower concentrations compared to other approaches (e.g., urine, oral fluid), marking hair drug testing as the most complex to execute.

Confirmation for any screening result testing positive is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive are cleansed before confirmation as necessary. The complete laboratory workflow from Accessioning to Confirmation is analyzed under both the CAP (College of American Pathologists) Hair designation and certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug usage extending up to 90 days, unlike urine tests which offer a shorter detection span.
• Difficult to falsify: It’s very arduous to manipulate a hair drug test, ensuring results are more reliable.
• Delivers historical information: It shows a timeline of drug usage over an interval, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: It generally takes about 5-7 days for substances to emerge in hair.
• Expense: Hair drug tests tend to be more costly than other drug testing techniques.
• Variability in outcomes: Factors like hair color and personal differences in hair growth can impact the level of drug metabolites in hair.

Note: While commonly called "hair follicle tests," the procedure actually examines the hair strand itself 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. 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.
