Hair Follicle Drug Testing - West Liberty, PA

What it is, How it works

Hair testing is now recognized as a formidable method for detecting drug and alcohol consumption. Hair captures a prolonged track record of alcohol and drug usage by encasing biomarkers within its growing strands. When collected near the scalp, hair offers up to a 3-month detection timeframe for alcohol and drugs. It's easy to collect, relatively tough to alter, and convenient to ship.

A 1.5-inch slice comprising roughly 200 hair strands (about the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for analysis. For EtG, additional tests, or tests beyond 10 panels, 150mg of the sample is necessary. It's advised to weigh the sample using a jeweler’s scale. If scalp hair isn't accessible, the equivalent quantity of body hair can be collected. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other hair forms (facial, axillary, etc.).

Process Overview

There are four primary steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially processed into a lab's system. This includes confirming that the sample was sealed and transported correctly, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.

Screening serves as an initial swift examination for drugs of abuse. While Screening is an economical approach to dismiss drug usage in most samples, a positive screen must be validated to stand up in court. Samples that are presumptively positive in Screening require further confirmation.

If a sample shows presumptive positivity during Screening, extra hair is taken from the initial sample and readied for Extraction. During this phase, drugs are drawn from hair at lower concentrations compared to other methodologies (such as urine or oral fluid), which explains why hair drug testing is one of the most complex methodologies to execute.

Confirmation of any positive screen is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection time: Hair drug tests can identify drug use up to 90 days, unlike urine tests with shorter detection periods.
• Hard to deceive: Cheating a hair drug test is quite challenging, enhancing result accuracy.
• Insight into past usage: It unveils a pattern of drug use over time, not merely recent activity.

Limitations:

• Inability to detect recent usage: It requires roughly 5-7 days before drugs become noticeable in hair.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Hair color and personal variations in hair growth can influence drug metabolite levels in hair.

Note: Although often termed as "hair follicle tests", this test analyzes 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.

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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
