Hair Follicle Drug Testing - Daggett, CA

What it is, How it works

Hair assessments have become recognized as an effective method for identifying drug and alcohol use. Hair captures a prolonged timeline of alcohol and drug consumption by preserving biomarkers within the fibers of the growing hair shaft. When taken near the scalp, hair can offer up to approximately a three-month detection timeframe for alcohol and various drugs. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for transportation.

A sample measuring 1.5 inches of roughly 200 hair strands (approximately the width of a #2 pencil) closest to the scalp will yield 100mg of hair, the ideal quantity for analysis. For EtG extensions or tests exceeding 10 panels, 150mg of hair is suggested. We advocate using a jeweler’s scale for measuring the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair may be sourced. When mentioning head hair, we mean scalp hair specifically. Body hair is defined as all other hair categories (facial, axillary, etc.).

Process Overview

The four primary phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial integration into a lab’s system. This comprises confirming that the sample was sealed and shipped accurately, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry not included by an electronic chain of custody system.

Screening carries out an initial swift evaluation for drugs of abuse. While Screening is a budget-friendly method to exclude drug consumption in the majority of samples, a screen yielding a positive result requires confirmation to be permissible in legal proceedings. Any samples that are tentatively positive in Screening need a further confirmation.

If a sample returns a tentative positive in Screening, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, drugs are retrieved from hair at a significantly lower concentration than in alternative methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can uncover drug consumption for up to 90 days, as opposed to urine assessments which possess a briefer detection period.
• Difficulty to deceive: Cheating a hair drug test is exceptionally challenging, resulting in more accurate outcomes.
• Offers historical data: It can illustrate a drug use pattern over a duration, not merely recent consumption.

Limitations:

• Cannot detect immediate use: Drugs take around 5-7 days to become identifiable in hair.
• Expense: Hair drug assessments are generally pricier than alternative drug testing techniques.
• Inconsistencies in outcomes: Elements such as hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: While commonly labeled as "hair follicle tests", the test itself examines the hair strand, 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.
