Hair Follicle Drug Testing - Edna, LA

What it is, How it works

The utilization of hair testing has become recognized as an effective means for detecting drug and alcohol consumption. Hair acts as a long-term record by embedding biomarkers within the strands as they grow. When extracted near the scalp, hair can reveal drug or alcohol usage over an approximate three-month period. Collecting hair samples is straightforward, challenging to tamper with, and convenient for shipment.

An ideal sample for both screening and confirmation is a 1.5-inch piece of approximately 200 strands (comparable to a #2 pencil in thickness), providing 100mg of hair. For EtG testing, additional analyses, and panels beyond 10, it is advised to use 150mg of the sample. It's recommended to use a jeweler’s scale for accuracy. If scalp hair is unobtainable, a similar amount of body hair can be used. When discussing head hair, it pertains exclusively to scalp hair, while body hair covers all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of drug test results entails four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a sample as it enters a laboratory's workflow. This step ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry missing from an electronic chain of custody system.

Screening provides an expedited evaluation for drug presence. While cost-effective for dismissing drug use in most samples, a positive screening result requires confirmation for judicial acceptance. Presumptive positives in Screening demand a secondary confirmation step.

For samples flagged in the Screening stage, additional hair is extracted from the original sample for the Extraction process. Drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening one of the most technical to perform.

Confirmation of positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples may be cleansed before confirmation. The complete laboratory workflow, from Accessioning to Confirmation, aligns with both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Resistance to manipulation: Hair drug tests are notably hard to deceive, ensuring result accuracy.
• Historical insight: Offers a snapshot of drug usage patterns over a duration, rather than only recent usage.

Limitations:

• Delayed detection of recent use: Drugs take about 5-7 days to manifest in hair samples.
• Expense: These tests generally incur higher costs compared to other drug testing options.
• Variability in findings: Factors like hair pigment and individual hair growth rates can influence the drug metabolite saturation in hair.

Note: Though frequently termed "hair follicle tests", the analysis focuses on the hair strand itself, not the underlying 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
