Hair Follicle Drug Testing - Silver City, NM

What it is, How it works

Hair testing is increasingly recognized as an effective method to identify drug and alcohol consumption. By capturing biomarkers within the fibers of growing hair, it provides a comprehensive record of substance use over time. Hair samples taken from close to the scalp can offer approximately a three-month detection period for both alcohol and drugs. This method is straightforward to execute, challenging to tamper with, and convenient to transport.

A sample comprising a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's thickness) near the scalp results in 100mg of hair, which is the optimal amount for examination and verification. For EtG, additional tests, or tests exceeding 10 panels, a sample weighing 150mg is advisable. A jeweler’s scale should be used to weigh the specimen. If scalp hair is not attainable, an equivalent portion of body hair can be utilized. When we mention head hair, we specifically mean scalp hair. Body hair denotes other hair types (such as facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial preparation of a sample within a laboratory's framework. This phase involves ensuring that the sample was properly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any extra data inputs not managed by an electronic chain of custody system.

Screening serves as an initial, rapid evaluation for substance abuse indicators. Although Screening is a budget-friendly way to eliminate drug usage in most cases, a confirmed result is mandatory for legal proceedings. Samples that test presumptively positive during Screening need additional confirmation.

Should a sample indicate a presumptive positive during Screening, more hair is extracted from the initial sample to prepare for Extraction. During this phase, the drug content is derived from hair substances at a significantly reduced concentration than found in other testing types (such as urine or oral fluid), making hair drug screening notably challenging to perform.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to confirm any positive Screening outcomes. All samples presumed positive undergo washing as necessary before confirmation. The complete laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair criteria and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more restricted detection period.
• Hard to manipulate: It is notably challenging to alter the results of a hair drug test, resulting in more precise outcomes.
• Retrospective data availability: This method can reveal a pattern of drug usage spanning an extended timeframe, not merely recent activity.

Limitations:

• Incapable of detecting recent usage: There is a delay of approximately 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing approaches.
• Result discrepancies: Elements such as hair color and individual hair growth variations may influence the drug metabolite concentration within the hair.

Note: Often termed as "hair follicle tests", the assessment actually analyzes the hair strand instead of the hair 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.
