Hair Follicle Drug Testing - Mayer, MN

What it is, How it works

Hair analysis is recognized as an effective method for identifying the consumption of drugs and alcohol. Hair serves as a long-term record of alcohol and substance intake by encapsulating biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair offers a detection range of up to around three months for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and hassle-free to transport.

A 1.5-inch section of about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp provides 100mg, which is the perfect amount for initial tests and subsequent confirmations. For enhanced tests like EtG or when exceeding 10 panels, 150mg is suggested. We advise using a jeweler’s scale for weighing the sample. In cases where scalp hair is unattainable, a similar volume of body hair can be used. The term head hair specifically refers to scalp hair, while body hair encompasses all other types (such as facial and axillary).

Process Overview

The laboratory workflow for processing a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial incorporation of a sample into a lab's system. This stage involves ensuring the sample was securely sealed and shipped, assigning a LAN (Laboratory Accessioning Number) randomly, and inputting any additional details not available through an electronic chain of custody system.

Screening conducts a preliminary review for substances of abuse. Though Screening is a cost-efficient approach to exclude drug use in most samples, any positive results require confirmation for legal admissibility. Samples that show a presumptive positive in Screening need a secondary verification.

If Screening indicates a presumptive positive, additional hair is taken from the original sample for Extraction. In this phase, substances are drawn out from hair at a much lower concentration than with other techniques (like urine or saliva), making hair drug screening a more challenging method to execute.

Verification of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive specimen is cleansed before confirmation as necessary. The whole lab process from Accessioning to Confirmation is audited in accordance with both the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests for drugs can identify usage up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Tough to manipulate: It's quite challenging to falsify a hair drug test, enhancing the accuracy of the outcomes.
• Offers chronological insight: It can demonstrate a pattern of drug intake over time, rather than just recent consumption.

Limitations:

• Cannot verify recent usage: Drugs require roughly 5-7 days to become detectable in hair.
• Expense: Hair drug screens are usually more costly than other testing techniques.
• Result variability: Variables such as hair color and personal hair growth differences can impact the level of drug metabolites within the hair.

Note: Although commonly referred to as "hair follicle tests", the analysis is performed on the hair strand itself, 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.
