Hair Follicle Drug Testing - Clarkston Heights, WA

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair accumulates biomarker evidence of substance use within its fibers, providing a historical account of up to roughly three months when gathered near the scalp. This method is straightforward to collect, relatively tamper-resistant, and convenient to transport.

To obtain a 100mg sample, optimal for both screening and confirmation, collect a 1.5-inch portion of around 200 hair strands (similar in width to a #2 pencil) closest to the scalp. For assessments like EtG, additional tests, and those exceeding 10 panels, a 150mg sample is advised. Usage of a jeweler’s scale for weighing the sample is recommended. If scalp hair is absent, equivalent body hair may be used. References to head hair pertain exclusively to scalp hair, whereas body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

There are four primary stages in the laboratory procedure for drug test analysis: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is initially processed into the laboratory’s system. This involves confirming that the sample was properly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody system.

Screening entails a preliminary assessment for drugs of abuse. Though Screening provides a cost-efficient way of excluding drug usage for most samples, a positive screen must be confirmed for legal admissibility. Samples yielding a presumptive positive in Screening require additional confirmation.

For samples indicating a presumptive positive during Screening, further hair is extracted from the initial sample to prepare for Extraction. This stage isolates drugs from hair at significantly lower concentrations compared to methods like urine or oral fluid testing, illustrating the complexity of hair drug analysis.

Positive results from Screening are validated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing positive are cleansed before confirmation as necessary. The complete laboratory workflow, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair oversight and conforms to ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests identify drug use for up to 90 days, outlasting the shorter detection period of urine tests.
• Resistance to tampering: Cheating a hair drug test is notably challenging, enhancing result reliability.
• Chronological insights: It offers a timeline of drug use, unlike methods that only identify recent consumption.

Limitations:

• Incapable of identifying recent ingestion: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier than alternative testing techniques.
• Result variability: Factors such as hair hue and individual growth variations affect drug metabolite levels in hair.

Note: Known colloquially as "hair follicle tests", analysis focuses on the hair strand, 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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
