Hair Follicle Drug Testing - Marcus, WA

What it is, How it works

Hair analysis has gained recognition as a robust method for detecting drug and alcohol usage. The fibers of a growing hair strand capture biomarkers, providing a long-term record of drug and alcohol use. When hair is collected near the scalp, it can offer up to a 3-month window for detecting drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch section containing approximately 200 strands of hair (similar in size to a #2 pencil) near the scalp weighs around 100mg, which is the optimal sample amount for testing and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg of hair is advised. It's best to use a jeweler’s scale to weigh the sample. If scalp hair can't be obtained, a comparable quantity of body hair can be used. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types (like facial or axillary hair).

Process Overview

The key steps in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab's system. This step authenticates that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any other data entry not supplied by an electronic chain of custody system.

Screening quickly assesses samples for drugs of abuse. Although it's a cost-effective method to check for drug usage in most samples, a positive result needs confirmation for court use. Samples testing presumptively positive during Screening must undergo secondary confirmation.

If Screening yields a presumptive positive, more hair is removed from the original sample and readied for Extraction. Drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging form to execute.

Confirmation of any positive Screen result is achieved using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo a wash before Confirmation if needed. The whole process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests that offer a shorter detection timeline.
• Difficult to manipulate: Cheating a hair drug test is notably hard, thus enhancing result accuracy.
• Provides use history: Unlike some methods, it can chart a pattern of usage over time, not merely recent intake.

Limitations:

• Can't reveal recent use: Detecting drugs in hair takes around 5-7 days.
• Expense: Hair drug testing tends to be pricier compared to other testing techniques.
• Variability in results: Differences such as hair color and personal hair growth variability can influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the test actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Within Marcus, WA, hair testing overtakes the urine approach due to its enhanced detection accuracy. Why Hair Testing Outshines Urine Testing lies in its longer detection window and efficacy.

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.
