Hair Follicle Drug Testing - Garyville, LA

What it is, How it works

Hair testing is recognized as an effective instrument for identifying usage of drugs and alcohol. Hair captures biomarkers within its fibers, presenting a long-term profile of alcohol and drug use. When obtained near the scalp, hair can offer approximately a 3-month detection timeline for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample of 1.5 inches with roughly 200 strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for analysis and validation. For EtG, additional components, and/or assessments surpassing 10 panels, 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be insufficient, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair only. "Body hair" encompasses all other forms (facial, axillary, etc.).

Process Overview

Processing a drug test result in the lab involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning manages the initial entry of a sample into the lab system. This entails confirming the sample’s seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening performs an initial rapid evaluation for drug presence. While efficient in ruling out drug use in most samples, a positive screen must be verified for court acceptance. Samples presumptively positive in Screening need further confirmation.

If a sample tests presumptively positive during Screening, more hair from the initial sample is extracted and processed for Extraction. Here, drugs are extracted from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.

Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are washed as necessary before confirmation. The full lab process from Accessioning to Confirmation undergoes review by both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug consumption for up to 90 days, whereas urine testing offers a shorter detection span.
• Challenging to manipulate: Cheating a hair drug test is exceptionally difficult, enhancing result accuracy.
• Offers historical insights: It can disclose patterns of drug consumption over time, not just recent usage.

Limitations:

• Unable to detect immediate usage: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests are usually more costly than alternative drug testing methods.
• Result variability: Hair color and individual hair growth variance can influence drug metabolite concentration in hair.

Note: The term "hair follicle tests" frequently used actually involves analyzing the hair strand, excluding 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.
