Hair Follicle Drug Testing - Imlay, NV

What it is, How it works

Hair testing is now recognized as an effective mechanism for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug intake by embedding biomarkers in the strands of the hair as it grows. When sourced close to the scalp, hair can present up to an approximately 3-month detection span for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.

A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will provide a sample of 100mg, which is optimal for screening and verification. For EtG, supplements, and/or assessments beyond 10 panels, 150mg of the sample is advised. We suggest checking the weight of the sample on a jeweler’s scale. If head hair is unavailable, a corresponding quantity of body hair may be taken. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory processing for a drug test outcome consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of a sample into a lab’s system. This entails verifying that the sample was correctly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody system.

Screening consists of a preliminary rapid verification for drugs of misuse. Screening offers a cost-efficient method to discount drug use in most samples, however, a positive screen must be validated to be admissible in legal proceedings. Samples that are tentatively positive in Screening require further confirmation.

If a sample shows a tentative positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are tentatively positive undergo washing before confirmation as needed. The whole laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug usage for up to 90 days, compared to urine tests which have a shorter detection period.
• Difficulty to cheat: Hair drug tests are very hard to fake, increasing result precision.
• Provides historical data: They reveal a pattern of drug consumption over time, not just recent activities.

Limitations:

• Cannot detect recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Cost: Hair drug tests are typically pricier than other drug testing approaches.
• Variations in results: Elements like hair color and individual differences in hair growth can influence drug metabolite levels in the hair.

Note: While often dubbed "hair follicle tests", the assessment actually examines the hair strand instead of 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.
