Hair Follicle Drug Testing - Mount Carmel, PA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. It offers a prolonged history of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When sampled close to the scalp, hair can indicate drug or alcohol use within approximately a three-month timeframe. The collection process is straightforward, challenging to tamper with, and easy to transport.

A sample consisting of 1.5 inches of hair, typically around 200 strands (equivalent to the circumference of a #2 pencil), obtained near the scalp, will yield 100mg, which is the preferred amount for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advisable. It's suggested to utilize a jeweler’s scale for measurement. In cases where scalp hair is absent, an equivalent quantity of body hair should be collected. 'Head hair' specifically means scalp hair, whereas 'body hair' includes any other types, like facial or axillary hair.

Process Overview

The laboratory analysis of a drug test consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample enters a lab’s system. This procedure involves checking the sample’s packaging and shipment integrity, allocating a LAN (Laboratory Accessioning Number), and completing any additional paperwork not already addressed by an electronic chain of custody.

Screening is a preliminary examination for drugs of abuse. It is a budget-friendly strategy to eliminate drug use in most samples. However, for legal purposes, a positive screening requires corroboration. All samples with an initial positive indication need subsequent verification.

For samples that test positive during Screening, further hair is extracted from the sample and prepped for Extraction. Here, drugs are retrieved from hair at significantly lower concentrations than those in alternative techniques (e.g., urine or oral fluid), making hair analysis notably challenging.

Positive screening results are verified via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirming, all samples that tested positive are washed as necessary. This comprehensive process, spanning Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests recognize drug use for up to 90 days, a benefit over urine tests with their shorter detection periods.
• Impenetrable to tampering: Cheating a hair test is notably tough, enhancing result reliability.
• Chronological use data: It reveals a usage pattern over time, rather than only indicating recent use.

Limitations:

• Lacks detection of immediate use: Drugs become noticeable in hair only after approximately 5 to 7 days.
• Expense: Generally, hair tests incur higher costs compared to other drug testing methods.
• Result variability: Factors like hair color and individual growth rates can influence drug metabolite levels in hair.

Note: While commonly called "hair follicle tests," the examination specifically considers the hair strand, not the underlying hair follicle.

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
