Hair Follicle Drug Testing - Salkum, WA

What it is, How it works

Hair analysis is recognized as a potent method for identifying drug and alcohol consumption. Hair strands provide an extensive timeline of substance use by capturing biomarkers within the growing fiber. When cut near the scalp, hair can offer a detection period of nearly three months for both alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient for transport.

A sample measuring 1.5 inches of roughly 200 hair strands (similar in diameter to a #2 pencil) nearest the scalp yields 100mg of hair, the ideal amount for both screening and confirmation. For EtG, additional factors, and/or tests exceeding 10 panels, 150mg of the sample is recommended. Using a jeweler's scale to weigh the sample is advised. If scalp hair is not present, an equivalent amount of body hair may be gathered. 'Head hair' solely refers to scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The key steps in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary processing of a sample into a laboratory's workflow. This entails ensuring the sample was appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any other data entry not captured by an electronic chain of custody system.

Screening provides an initial, quick assessment for drug abuse. While it’s a cost-efficient method to eliminate drug use for most samples, a positive screen must be validated to be sufficient for legal proceedings. Samples that are tentatively positive in Screening necessitate a secondary verification.

If a sample tests presumptively positive in the Screening phase, additional hair is extracted from the original sample for Extraction. Here, the drugs are removed from hair at a substantially lower concentration than other methods (e.g., urine or oral fluid), indicating why hair drug testing is a complex technique to administer.

Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples are cleansed before confirmation as required. The full lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing captures drug use for up to 90 days, whereas urine tests offer a more constrained detection period.
• Resistance to tampering: Cheating a hair drug test is extremely challenging, ensuring more accurate outcomes.
• Provides historical insight: It offers a timeline of drug usage over a duration, not merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-ingestion.
• Expense: Hair drug tests tend to be more costly compared to other drug testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth may influence drug metabolite concentration in hair.

Note: Although frequently termed as "hair follicle tests", the test actually examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Salkum, WA, hair follicle tests offer a definitive edge over urine tests. Superior detection accuracy is achieved, providing a robust means of identifying substance use. Unlike urine tests, which cover a short timeframe, hair testing gives a historical record of drug usage, proving more reliable for comprehensive assessments.

Extended Detection Window

The hair follicle testing method employed in Salkum, WA allows for an extended detection window, capturing drug use history for up to 90 days. Employers benefit from this extended period as it provides a more complete overview of an individual's drug-use pattern, aiding in more informed decision-making.

Tamper-Resistant Testing Method

In Salkum, WA, the tamper-resistant nature of hair follicle tests greatly minimizes the chance of adulteration. This method ensures that the samples provided remain unaltered, therefore delivering results that stakeholders can trust without question.

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.
