Hair Follicle Drug Testing - Marco, LA

What it is, How it works

The utilization of hair analysis is increasingly recognized as a compelling approach for detecting alcohol and drug consumption. Hair captures long-term exposure to substances by embedding biomarkers within the hair's growing strand. If obtained near the scalp, hair can reveal alcohol and drug use for up to a three-month period. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch section comprised of roughly 200 strands of hair (resembling the size of a #2 pencil) nearest to the scalp offers 100mg of hair, the optimal quantity for tests and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a recommendation of 150mg of the sample is advised. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent volume of body hair may be taken. References to head hair pertain exclusively to scalp hair; body hair encapsulates all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of drug test outcomes involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample enters a laboratory’s protocol. Tasks include confirming the sample's proper sealing and shipment, allocating a unique LAN (Laboratory Accessioning Number), and fulfilling any supplemental data entry lacking from an electronic custody system.

Screening provides an initial, swift assessment for substance abuse. Although Screening efficiently eliminates drug use suspicion in most cases, positive results require confirmation for legal acceptability. Samples indicating presumptive positives in Screening necessitate further verification.

Should a sample test positive in the Screening phase, additional hair from the original sample is extracted for further processing. In Extraction, drugs are separated from hair at lower concentrations than other methods (e.g., urine or oral fluid), reflecting why hair drug testing is a complex practice to conduct.

The validation of positive screening findings is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples undergo washing before confirmation as warranted. The comprehensive laboratory progression from Accessioning to Confirmation is assessed in alignment with both CAP (College of American Pathologists) Hair specifications and accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests unveil substance use over a 90-day span, surpassing the shorter time frames of urine tests.
• High resistance to manipulation: Cheating on a hair drug test is notably challenging, enhancing the reliability of results.
• Chronological data provision: It reveals patterns of prolonged drug use, not merely recent consumption.

Limitations:

• Inability to detect immediate use: A window of 5-7 days is needed for substances to manifest in hair.
• Expense: Hair drug testing incurs greater costs compared to other methodologies.
• Result discrepancies: Influences like hair color and personal hair growth variations can alter drug metabolite concentrations in hair.

Note: Typically called "hair follicle tests", these assessments scrutinize the hair itself and 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.
