Hair Follicle Drug Testing - Pompeys Pillar, MT

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol use. Hair offers an extended history of substance use by capturing biomarkers within the fibers of the hair strands as they grow. When taken close to the scalp, hair can reveal a detection period of about three months for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, it is advisable to use 150mg of the sample. We suggest measuring the sample using a jeweler's scale. If scalp hair is not available, a comparable amount of body hair may be used. In the context of head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the first processing stage of a sample within a lab's system. This step includes ensuring the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and filling out any needed data entry absent from an electronic chain of custody setup.

Screening makes an initial, efficient examination for drugs of abuse. While Screening is a cost-effective means to dismiss drug use for most samples, a positive screening result requires confirmation to hold in a legal context. Samples showing presumptive positivity during Screening need secondary confirmation.

For samples deemed presumptive positive during Screening, additional hair is drawn from the original sample for the Extraction phase. In this phase, drugs are isolated from hair at significantly lower levels than with other techniques (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies to execute.

Confirmation of any Screening positivity is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing before confirmation if necessary. The whole laboratory process, from Accessioning to Confirmation, is reviewed in light of both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a span of up to 90 days, surpassing urine tests, which have a more limited detection timeframe.
• Challenging to manipulate: Cheating a hair drug test is extremely difficult, facilitating more precise outcomes.
• Offers chronological usage data: It can reveal a pattern of substance use over time, not merely recent consumption.

Limitations:

• Inability to identify recent consumption: It usually requires 5-7 days before drugs are traceable in hair.
• Expense: Hair drug testing generally incurs higher costs than other drug testing approaches.
• Result variability: Factors like hair color and individual differences in hair growth can influence the drug metabolite levels in hair.

Note: Although often termed "hair follicle tests," the analysis targets 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.
