Hair Follicle Drug Testing - Almelund, MN

What it is, How it works

Hair analysis is recognized as a significant method for identifying drug and alcohol usage. Hair retains a long-term record of alcohol and other substances by embedding biomarkers within the strands of growing hair. When taken near the scalp, hair can yield a detection period of up to roughly three months for alcohol and other substances. It is straightforward to collect, somewhat hard to alter, and convenient to ship.

Collecting a sample of 1.5 inches of approximately 200 hair strands (around the size of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional testing, and/or tests exceeding 10 panels, a sample of 150mg is advisable. It's recommended to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. When discussing head hair, we refer solely to scalp hair. Body hair encompasses all other hair classifications (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial integration of a sample into a lab's system. This process verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not included by an electronic chain of custody system.

Screening involves an elementary assessment for substances of abuse. Although Screening is economical for eliminating drug use in most samples, a positive screen must be verified to be legally acceptable. Any samples that show presumed positivity during Screening necessitate further confirmation.

Should a sample exhibit presumed positivity in the Screening phase, more hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are separated from hair at notably lower concentrations than in other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Confirmation of any positive screening is conducted via GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive are cleansed before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is conducted per the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing identifies drug use for up to 90 days, compared to the shorter range of urine tests.
• Low likelihood of deception: Hair drug testing is hard to circumvent, enhancing the precision of the results.
• Chronological usage data: It reveals a pattern of drug consumption over time, not limited to recent usage.

Limitations:

• No recent use detection: Drugs become detectable in hair roughly 5-7 days after use.
• Expense: Generally, hair drug tests are costlier than alternative methods.
• Result variability: Factors such as hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: The term "hair follicle tests" is often used, but the test actually analyzes the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Almelund, MN, hair follicle testing surpasses traditional urine testing due to its superior detection accuracy and reliability. Hair tests can identify substance use over an extended period, unlike urine tests, which often miss longer-term usage.

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.
