Hair Follicle Drug Testing - East Linn, OR

What it is, How it works

Hair analysis is recognized for its efficacy in detecting substances and alcohol intake. Hair captures a prolonged index of substance consumption by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can offer roughly a 90-day window for detecting alcohol and substances. It's easy to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp provides 100mg, which is the preferred quantity for assessment and validation. For EtG, additional tests, and/or panels exceeding 10, obtaining 150mg of the sample is advised. It's suggested to use a jeweler’s scale for measuring the sample. If scalp hair isn't present, an equivalent body hair sample can be used. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other types (facial, underarm, etc.).

Process Overview

There are four principal stages in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the primary handling of a sample within a lab’s framework. This step includes confirming the sample was sealed and sent correctly, generating a random LAN (Laboratory Accessioning Number), and completing other data entry tasks absent from an electronic custody chain.

Screening entails an initial rapid evaluation for substance misuse. Although cost-effective for eliminating drug use in most samples, a positive screen necessitates further confirmation for legal acceptance. Presumptive positive samples in Screening demand additional verification.

Should a sample test as presumptively positive in Screening, more hair is extracted from the original sample for Preparation during Extraction. In this phase, substances are sourced from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug testing the most challenging method to execute.

Confirmation of any screen-positive findings is via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is governed by both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug assays can identify substance use for up to 90 days, as opposed to urine assays which offer a shorter timeframe.
• Challenging to manipulate: It is notably tough to bypass a hair drug test, ensuring results are more reliable.
• Offers historical insight: It provides a timeline of substance use over a duration, not just recent consumption.

Limitations:

• Cannot spot immediate use: Drugs become visible in hair approximately 5-7 days post-consumption.
• Expense: Hair drug assessments generally entail greater costs compared to other testing options.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite levels in hair.

Note: Though often called "hair follicle tests", the actual test evaluates the hair shaft rather than the underlying follicle.

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.
