Hair Follicle Drug Testing - Johnson City, OR

What it is, How it works

Hair testing is recognized as a highly effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug use by embedding biomarkers within the strands of hair as they grow. Collected near the scalp, hair can offer up to a three-month detection window for substances, being straightforward to gather, relatively tamper-resistant, and simple to transport.

A sample measuring 1.5 inches of around 200 hair strands, about the thickness of a #2 pencil, closest to the scalp supplies 100mg of hair, which is the perfect quantity for screening and validation. For EtG, additional screenings, or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not accessible, the equivalent amount of body hair can be used. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The core stages in the lab handling of a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary steps of integrating a sample into a lab's system, ensuring the sample was properly sealed and delivered, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any outstanding data entry not handled by an electronic custody system.

Screening entails an initial rapid assessment for drug misuse. While Screening is a budget-friendly approach to eliminating drug use in most cases, a positive screening result necessitates confirmation for legal acceptability. Presumptively positive samples from Screening must undergo a secondary confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the primary specimen and readied for Extraction. In this phase, drugs are extracted from hair at a remarkably lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.

Confirmation of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive specimens are cleansed before confirmation as needed. From Accessioning to Confirmation, the entire lab procedure is examined under the CAP (College of American Pathologists) Hair distinction and accredited according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can detect drug use for up to 90 days, unlike urine tests, which have a shorter duration.
• Hard to manipulate: Cheating a hair drug test is particularly challenging, making results more reliable.
• Offers historic data: It provides a usage trend of drugs over time, rather than just indicating recent use.

Limitations:

• Cannot identify recent use: It takes around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Diverse results: Elements such as hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly referred to as "hair follicle tests," these tests analyze the hair strand rather than the follicle below 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.
