Hair Follicle Drug Testing - Meadville, PA

What it is, How it works

Hair analysis is increasingly viewed as a robust method for detecting drug and alcohol consumption. By trapping biomarkers within the fibers of hair as it grows, it can offer an extensive history of alcohol and other substances. When gathered from near the scalp, the hair sample can reveal substance use over a roughly 3-month span. This method is straightforward to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch segment of around 200 hairs (approximately the thickness of a #2 pencil) near the scalp equates to 100mg of hair, which is ideal for both screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, it's advisable to use 150mg of the specimen. A jeweler’s scale is suggested for weighing the sample. If scalp hair is unavailable, a comparable amount of body hair can be used. 'Head hair' pertains solely to scalp hair, whereas 'body hair' includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating the sample into a lab's system. This step checks that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any leftover data entry absent from an electronic chain of custody system.

Screening conducts an initial swift assessment for substance abuse. Though Screening offers a cost-effective method to eliminate drug use in most samples, any positive results must be confirmed for legal admissibility. Presumptively positive samples in Screening require a follow-up confirmation.

If the Screening phase suggests a positive result, additional hair is taken from the original sample for the Extraction process. This step isolates drugs from hair at a much lower concentration than other techniques (like urine or oral fluid), underscoring the complexity of hair drug analysis.

Confirmation of any screening results indicating positivity is done via GC/MS, GC/MS/MS, or LC/MS/MS. If necessary, all presumptive positive samples are cleaned before confirmation. The whole lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with a briefer detection period.
• Challenge to falsify: Cheating a hair drug test is very challenging, enhancing result reliability.
• Offers historical insight: It provides a record of drug use patterns over time, not just recent use.

Drawbacks:

• Inability to detect recent use: Detectable levels in hair take around 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier compared to other methods.
• Result variability: Aspects like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis concerns the hair strand rather than 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.

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.
