Hair Follicle Drug Testing - Navajo, NM

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol usage. This is because hair offers an extended timeline of alcohol and drug ingestion by capturing biomarkers within the fibers of the growing hair shaft. When clipped close to the scalp, hair allows for up to a 3-month period of detection for alcohol and other substances. Hair collection is straightforward, resistant to tampering, and convenient for transportation.

A 1.5-inch length of roughly 200 hair strands (equivalent to the circumference of a #2 pencil) near the scalp yields approximately 100mg of hair, which is ideal for screening and confirmation. For EtG tests, additional testing, and/or panels exceeding 10, a sample weight of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable amount of body hair may be taken. References to head hair pertain solely to scalp hair, while body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Introduction

The primary laboratory processes involved in producing a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab’s system. This process involves checking that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by electronic chain of custody systems.

Screening is an initial quick assessment for drugs of abuse. This cost-effective process helps eliminate drug use in most samples, although a positive screening result must be confirmed for admissibility in legal contexts. Any samples that yield a presumptive positive in Screening will necessitate a secondary confirmation.

For samples that test presumptively positive during Screening, additional hair is taken from the original sample and prepped for Extraction. In this phase, drugs are drawn from hair at concentrations significantly lower than those in other methods (like urine or oral fluid), which makes hair drug testing the most challenging method to conduct.

Confirmation of any positive screening outcome is achieved through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives are cleansed as required. The complete lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 criteria.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use up to 90 days, whereas urine tests have a shorter detection range.
• Hard to manipulate: It is notably challenging to manipulate a hair drug test, ensuring more reliable results.
• Tracks historical usage: Hair testing can outline a pattern of drug consumption over time, not merely recent usage.

Drawbacks:

• Recent usage undetected: Drugs take about 5-7 days to become discernible in hair.
• Expense: Generally, hair drug tests incur greater costs than other testing methodologies.
• Result variability: Factors such as hair color and individual hair growth differences may impact the metabolite concentration in hair.

Reminder: Although commonly referred to as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
