Hair Follicle Drug Testing - Hathaway, LA

What it is, How it works

Hair testing is acknowledged as a robust method for identifying drug and alcohol usage. Hair fibers capture biomarkers over time, offering a prolonged history of substance ingestion. When trimmed near the scalp, hair samples can reveal up to a three-month history of alcohol and drug use. Its collection is straightforward, tampering is somewhat challenging, and shipping is uncomplicated.

A 1.5-inch segment, roughly 200 hair strands (similar to a #2 pencil's thickness), nearest to the scalp provides 100mg of hair, ideal for precise screening and validation. For EtG, extended panels, or over 10-panel tests, 150mg is advised. It's best to weigh the hair sample using a jeweler’s scale. If scalp hair isn't present, an equivalent quantity of body hair can be used. Scalp hair specifically refers to head hair; body hair pertains to all other kinds (facial, axillary, etc.).

Process Overview

The essential phases in lab processing for drug testing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step, integrating the sample into the laboratory’s system. This step ensures the sample’s seal and shipping integrity, assigns a LAN (Laboratory Accessioning Number), and completes additional data entry omitted by electronic chain systems.

Screening includes an initial assessment for drug presence. Though cost-efficient for excluding drug use in most cases, a positive screen must be validated for legal acceptability. Positive presumptive screens necessitate further confirmation.

Should Screening yield a presumptive positive, additional hair from the initial sample is prepared for Extraction. During Extraction, drugs are detected in hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting hair drug screening’s complexity.

Confirmation of positive screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positives are sanitized pre-confirmation if necessary. The entire sequence from Accessioning to Confirmation receives assessment under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug uptake over 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is considerably difficult, enhancing result reliability.
• Chronological usage data: These tests reflect a pattern of drug use across a timeframe, rather than just recent consumption.

Limitations:

• Cannot capture recent intake: Detection of drugs in hair takes about 5-7 days.
• Expense: Generally, hair drug tests are pricier than other methods.
• Result variability: Differences in hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although termed "hair follicle tests", the analysis focuses on the hair strand rather than 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.
