Hair Follicle Drug Testing - Brinnon, WA

What it is, How it works

Hair testing is increasingly recognized as a potent method for identifying drug and alcohol consumption. It provides a comprehensive timeline of substance use by embedding biomarkers within the strands of hair as it grows. When taken from near the scalp, hair samples offer a detection timeframe of up to roughly three months for both alcohol and drugs. Hair samples are simple to gather, hard to tamper with, and straightforward to transport.

A segment of hair measuring 1.5 inches, consisting of roughly 200 strands (akin to the width of a #2 pencil), closest to the scalp yields about 100mg of hair, the optimal quantity for screening and confirmation processes. For EtG, additional tests, and/or screenings beyond 10-panel tests, a sample of 150mg is suggested. It is advisable to weigh the hair sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be utilized. References to head hair specifically mean scalp hair, whereas body hair includes all other types such as facial and axillary hair.

Process Overview

The fundamental stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial incorporation of a specimen into a lab’s database, verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.

Screening presents a preliminary, swift examination for drug presence. While cost-effective for excluding drug use in most samples, a positive screen needs confirmation for legal acceptance. Samples with a presumptively positive result in Screening require an additional confirmation.

For presumptively positive samples identified during Screening, added hair from the initial sample is prepared for Extraction, involving drug removal from hair at significantly lower concentrations than in other approaches (e.g., urine or oral fluid), making hair screening the most challenging technique.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed as necessary before confirmation. The entire laboratory process from Accessioning through Confirmation is evaluated following both the CAP (College of American Pathologists) Hair criteria and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use for up to 90 days, unlike urine tests, which have a shorter detection period.
• Difficult to manipulate: Cheating a hair drug test is notably challenging, ensuring more precise results.
• Historical insight: It renders a timeline of drug use over a duration, indicating patterns beyond recent use.

Limitations:

• Inability to detect recent use: It generally takes between 5-7 days for drugs to become discernible in hair.
• Expense: Hair drug testing is typically more costly than alternative testing methods.
• Result variability: Factors such as hair color and individual hair growth rates can influence the level of drug metabolites in hair.

Note: Though often termed as "hair follicle tests", the actual testing analyzes the hair strand rather than the hair 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.
