Hair Follicle Drug Testing - Lake Oswego, OR

What it is, How it works

Hair testing is acknowledged as a significant means for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug traces by capturing biomarkers within the fiber of the developing hair. When taken near the head, hair samples can reveal up to roughly a 3-month period of drug and alcohol presence. Collecting hair is straightforward, somewhat challenging to tamper with, and convenient to transport.

A 1.5-inch segment containing approximately 200 hair strands (similar to a #2 pencil) clipped near the scalp gives 100mg of hair, which is ideal for examination and confirmation. For EtG, additional tests, and/or panels over 10, acquiring 150mg of the hair is advised. It is suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equal volume of body hair may be obtained. When indicating head hair, we mean scalp hair specifically. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The drug testing process in the lab encompasses four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial integration into a lab’s system. This includes ensuring the sample is sealed and posted correctly, designating a random LAN (Laboratory Accessioning Number), and finishing any additional data input absent from an electronic chain of custody setup.

Screening represents an initial rapid evaluation for potential drug use. While screening is an economical approach to dismiss drug consumption among most samples, a positive result must be corroborated to be recognized in legal proceedings. Any sample that shows a tentative positive outcome during screening mandates further confirmation.

If the screening phase indicates a positive presumptive result, more hair is extracted from the initial sample for the Extraction phase. Here, drugs are eluted from hair at significantly lower levels than in techniques like urinalysis or oral fluid analysis, thus making hair drug testing a highly intricate procedure.

Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples showing presumptive positives undergo washing before confirmation as necessary. The whole laboratory procedure from Accessioning to Confirmation is scrutinized under the College of American Pathologists' Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug examinations can recognize drug consumption over a span of up to 90 days, unlike urine tests which possess a shorter detection span.
• Hard to tamper with: Cheating a hair drug test is quite arduous, enhancing result precision.
• Delivers usage history: It sheds light on a pattern of drug usage across time, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: It takes roughly 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are typically pricier compared to other drug testing techniques.
• Variable results: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although often called "hair follicle tests", the test analyzes the hair strand rather than the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
