Hair Follicle Drug Testing - Bernice, LA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other substances by enclosing biomarkers within the fibers of the developing hair strand. Collected near the scalp, hair can offer approximately a 3-month detection range for alcohol and other substances. It is simple to collect, somewhat hard to alter, and straightforward to transport.

A sample length of 1.5 inches with around 200 hair strands (resembling a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of the specimen is suggested. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be gathered. When referencing head hair, it implies scalp hair specifically. Body hair corresponds to any other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug testing results includes four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample within a laboratory’s system. It involves verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.

Screening is a quick initial drug check. Although Screening is an economical method to exclude drug usage in most samples, positive findings must be verified to be court admissible. Samples that are initially positive in Screening require further confirmation.

If a sample tests positive at the Screening stage, additional hair is taken from the initial sample and prepared for Extraction. This step involves extracting drugs from hair at a lower concentration than other methods (such as urine or oral fluid), making hair drug analysis the most challenging practice.

Any positive Screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation when necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug use for up to 90 days, unlike urine tests which have a shorter detection window.
• Difficult to deceive: It is very challenging to alter hair drug tests, ensuring more accurate results.
• Provides historical insight: It reveals patterns of drug use over time, not just recent consumption.

Limitations:

• Cannot discern recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing generally costs more than other methods.
• Result variations: Factors like hair color and individual hair growth may influence drug metabolite levels in hair.

Note: Although commonly referred to as "hair follicle tests", the examination targets the hair strand rather than the scalp's hair follicle.

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.
