Hair Follicle Drug Testing - Gaston, NC

What it is, How it works

Hair analysis is recognized as a compelling approach for identifying drug and alcohol consumption. Hair captures a long-lasting record of alcohol and drug intake by embedding biomarkers in the strands as they develop. When taken close to the scalp, hair can present roughly a three-month detection timeframe for alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and convenient to transport.

A 1.5-inch piece consisting of approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for analysis and verification. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the sample is recommended. Should scalp hair be unavailable, a comparable quantity of body hair can be taken. "Head hair" denotes only scalp hair. "Body hair" encompasses all other varieties (facial, axillary, etc.).

Process Overview

The procedure for laboratory processing of a drug test result covers four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning necessitates the initial sample processing into a lab's framework. This process involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not catered by an electronic chain of custody system.

Screening entails a quick preliminary assessment for substance abuse. Although Screening is a budget-friendly strategy for excluding drug use in most samples, a confirmed screen is essential for legal admissibility. Samples showing a presumptive positive in Screening require further confirmation.

Should a sample show presumptive positivity in the Screening phase, additional hair is retrieved from the original sample for Preparation. Drugs are separated from hair at a notably lower concentration than in other methods (e.g., urine or oral fluid), rendering hair drug analysis the most challenging procedure to execute.

A positive screening outcome undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before Confirmation as necessary. The comprehensive lab approach from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug evaluations can spot drug usage for up to 90 days, unlike urine tests which have a more limited detection timeframe.
• Hard to deceive: Deceiving a hair drug assessment is quite difficult, heightening result accuracy.
• Provides usage patterns: Offers insights into drug consumption trends over time, not just recent usage.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to be noticeable in hair.
• Cost: Generally, hair drug evaluations are pricier compared to alternative drug testing methods.
• Result variability: Hair color and individual hair growth variations can impact the level of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the assessment examines the hair strand, 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.
