Hair Follicle Drug Testing - Wilkesboro, NC

What it is, How it works

Hair tests are now acknowledged as an effective method for uncovering drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug usage by embedding indicators within the hair shaft as it grows. When taken near the scalp, hair offers approximately a three-month detection period for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to dispatch.

A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for both screening and verification. For EtG, extras, and/or more than 10-panel tests, 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a comparable volume of body hair can be gathered. Head hair specifically means scalp hair, while body hair includes all other types (facial, underarm, etc.).

Process Overview

The four fundamental procedures in processing a lab drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step in managing a sample in a lab's system, which entails confirming the sample’s proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any missing data not already covered by an electronic custody system.

Screening offers a speedy initial inspection for substance abuse. While it's cost-efficient for negating drug usage in most cases, a positive in Screening requires validation to hold in legal proceedings. Presumptive positives in Screening need additional validation.

If there's a presumptive positive indicator in Screening, further hair is extracted for the Extraction phase. During Extraction, drugs are removed from hair at low concentrations compared to other methods (e.g., urine or saliva), which makes hair drug screening a complex process.

Confirmation for a positive Screen involves using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo required washing prior to Confirmation. Each laboratory stage from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can trace drug use up to 90 days, unlike urine tests with a shorter timeframe.
• Difficult to manipulate: Cheating a hair drug test is extremely challenging, ensuring more precise outcomes.
• Offers usage history: It reveals patterns of drug use over time, not just recent application.

Limitations:

• Inability to detect recent usage: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug testing generally costs more than other drug test methods.
• Result variations: Factors like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the examination focuses on the hair shaft and not the follicle below 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.
