Hair Follicle Drug Testing - Brooks, AL

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a repository of long-term alcohol and drug usage by holding biomarkers in the strands of hair as they grow. When obtained near the scalp, hair can offer an up to 3-month timeframe for detecting alcohol and other drugs. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches that consists of roughly 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield around 100mg, which is optimal for both screening and confirmation purposes. For EtG, add-ons, and any tests surpassing 10 panels, a sample weighing 150mg is suggested. We advise measuring the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. When referencing head hair, it denotes only scalp hair, while body hair includes all other types like facial and axillary hair.

Process Overview

The core steps in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within the laboratory’s framework. This step verifies that the sample is correctly sealed and delivered, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data not supplied by an electronic chain of custody system.

Screening involves a preliminary check for drugs of abuse. While this stage provides an economical approach to negate drug use in most cases, a positive result demands confirmation for legal admissibility. Samples indicating presumptive positivity in Screening necessitate secondary confirmation.

In instances of presumptive positivity during Screening, additional hair from the primary sample is used for Extraction. At this phase, drugs are extracted from hair at a significantly lower concentration than methods such as urine or oral fluid testing, thereby making hair drug screening a more challenging method to execute.

Verification of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if required. The complete process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair guidelines and compliance with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, unlike urine tests which have a shorter span.
• Cheat-proof: The difficulty in manipulating a hair drug test enhances accuracy.
• Offers historical insights: Provides a record of drug consumption over time, beyond recent use alone.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing incurs higher costs than other methods.
• Result variability: Hair color and individual hair growth differences can alter drug metabolite concentrations in hair.

Note: Despite the term "hair follicle tests", the analysis is performed on the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Brooks, AL, hair follicle testing stands out as a superior method compared to traditional urine tests. The significant benefits of hair testing include better detection accuracy and reliability over longer periods.

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.
