Hair Follicle Drug Testing - Belmont, WA

What it is, How it works

Hair analysis is now considered an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of substance intake by embedding biomarkers within the hair strand as it grows. When cut near the scalp, hair can offer a detection range of nearly 3 months for alcohol and various drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.

Securing a 1.5-inch length of approximately 200 hair strands (similar to a #2 pencil's thickness) closest to the scalp provides 100mg of hair, the optimum sample size for analysis and verification. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advisable. Using a jeweler's scale for measuring the size is suggested. If scalp hair cannot be obtained, a similar quantity of body hair is permissible. The term head hair pertains solely to scalp hair, while body hair includes all other types (such as facial and axillary hair).

Process Overview

The process of lab processing a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with integrating a sample into a lab's system. This process includes checking that the sample is properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and performing any data entry not supported by an electronic custody tracking system.

Screening is a preliminary rapid evaluation for illicit substances. This cost-efficient method helps eliminate drug presence in most samples, though a positive screening result requires further confirmation for legal validation. Samples that test positive provisionally during Screening need a backup verification.

Should a sample indicate a presumptively positive result during Screening, additional hair is extracted from the original sample for the Extraction phase. At this stage, substances are derived from hair at significantly lower concentrations compared to other techniques (like urine or oral fluids), making hair drug screening the most complex technique to execute.

Confirming any positive screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo a cleansing process prior to confirmation when necessary. The comprehensive lab procedure from Accessioning to Confirmation is assessed under the strict guidelines of the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Prolonged detection duration: Hair drug tests can identify drug usage for as long as 90 days, whereas urine tests cover a shorter timeframe.
• Challenging to manipulate: Cheating on a hair drug test is extremely difficult, which ensures more reliable outcomes.
• Historical usage insight: It reveals a pattern of substance use over time, not merely recent consumption.

Drawbacks:

• Incapable of identifying recent use: It requires about 5-7 days for substances to be observable in hair.
• Expense: Generally, hair drug tests are costlier than other drug testing techniques.
• Result variability: Aspects such as hair color and individual hair growth factors can influence drug metabolite concentration in hair.

Note: Commonly known as "hair follicle tests", these tests actually scrutinize the hair strand and 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.
