Hair Follicle Drug Testing - Mount Rainier, MD

What it is, How it works

Hair analysis has emerged as a formidable method for detecting drug and alcohol usage. Hair can capture a lengthy record of alcohol and drugs by embedding biomarkers within the hair fibers as they grow. When taken from near the scalp, hair can offer up to roughly a 3-month detection period for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and convenient to ship.

An ideal sample for testing and validation involves a 1.5-inch section, or about 200 hair strands (comparable to a #2 pencil in size), gathered closest to the scalp, yielding 100mg of hair. For EtG, additional testing, or tests beyond 10 panels, 150mg of the sample is advised. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair may be used. "Head hair" refers strictly to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).

Process Overview

The main stages in laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary processing of a sample into a lab’s system. This process confirms the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any other data entry that an electronic chain of custody system doesn't cover.

Screening conducts an initial quick check for substance abuse. Screening is cost-effective for dismissing drug use in most samples; however, a positive screen must be validated for court acceptance. Any samples tentatively positive during Screening must undergo secondary validation.

If a sample is tentatively positive in the Screening phase, more hair is taken from the original sample and processed for Extraction. Here, drug extraction from hair occurs at lower concentrations than other methods (such as urine or saliva), making hair drug screening a challenging methodology.

Confirmation of any positive screening results is done via GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The full laboratory procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Challenging to cheat: Cheating a hair drug test is extremely difficult, enhancing the accuracy of results.
• Provides historical insights: It can reveal a usage pattern over time, not just recent consumption.

Limitations:

• Recent use undetectable: It takes around 5-7 days for drugs to be traceable in hair.
• Higher cost: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors like hair color and individual growth differences can alter drug metabolite concentration in hair.

Note: Often called "hair follicle tests," the test examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers several advantages over traditional urine tests in Mount Rainier, MD. One significant benefit is superior detection accuracy. Hair testing can identify substance use over a much longer period than urine tests, providing a more reliable history.

Another benefit is its unmatched reliability. While urine tests may be influenced by recent activity or tampering, hair tests present a stable and consistent detection method, minimizing potential discrepancies.

Extended Detection Window

The extended detection window of hair follicle testing offers a substantial advantage in Mount Rainier, MD, tracing drug use over the course of up to 90 days. This prolonged period affords a more comprehensive understanding of an individual's substance habits.

Employers gain access to an extensive substance use history, thanks to the persistent and historical data provided by hair testing. This insight aids in evaluating prospective or current employees beyond recent drug activity.

Tamper-Resistant Testing Method

Hair follicle tests significantly reduce the risk of tampering in Mount Rainier, MD. This method offers tamper-resistant capabilities, ensuring the integrity of the sample remains intact throughout the process.

Ensuring accurate and reliable test results, hair follicle testing serves as the optimal method, leaving minimal room for manipulation, unlike urine samples which can be easily compromised.

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.
