Hair Follicle Drug Testing - Berry, AL

What it is, How it works

Hair testing has emerged as a significant tool for detecting drug and alcohol consumption. Hair offers an extensive history of alcohol and drug use by holding biomarkers within the strands as they grow. Hair taken near the scalp can reveal a roughly 3-month period of alcohol and drug detection. Collection is easy, it's relatively tamper-proof, and it's straightforward to transport.

Providing a sample that's 1.5 inches long with around 200 hair strands (equivalent to a #2 pencil) yields 100mg of hair, ideal for both screening and confirmatory tests. For EtG, add-ons, or tests exceeding 10 panels, a suggestion of 150mg is ideal. It is advisable to weigh the sample using a jeweler's scale. In instances where scalp hair isn't present, an equivalent portion of body hair may be used. When we mention head hair, we specifically mean scalp hair. All other hair refers to body hair, like facial or axillary hair.

Process Overview

There are four principal stages in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the inaugural handling of a sample into a lab's system. This process involves ensuring the sample's seal and shipment were correct, allocating a random LAN (Laboratory Accessioning Number), and finishing any leftover data entry not covered by the electronic chain of custody system.

Screening refers to an initial, swift evaluation for drug substances. Although Screening is a cost-efficient method for ruling out drug use in most samples, a positive screen demands a confirmation for it to stand in court. Samples with presumptive positives during Screening require further confirmation.

Should Screening suggest a positive result, more hair is extracted from the initial sample for Extraction. During this step, drugs are derived from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), which is why hair drug testing is more challenging to execute.

The Confirmation for any positive screen occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a cleaning before Confirmation if necessary. The comprehensive lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation measures.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage up to 90 days back, unlike urine tests with a lesser detection duration.
• Hard to tamper with: Cheating on a hair drug test is quite challenging, leading to more reliable outcomes.
• Offers historical insight: It outlines a user's drug consumption over time, not just recent activity.

Limitations:

• Inability to spot recent use: Drugs require 5-7 days to manifest in hair.
• Expense: Hair drug tests typically cost more than other testing techniques.
• Result disparities: Elements such as hair color and person-to-person hair growth rates can impact the level of drug metabolites in hair.

Note: Despite being called "hair follicle tests", the test analyzes the hair strand itself, 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.
