Hair Follicle Drug Testing - Echo Lake, WA

What it is, How it works

Hair testing is increasingly recognized as a potent method for identifying drug and alcohol use. Hair captures a long-term record of alcohol and other drugs by embedding biomarkers in the strands of growing hair. When sampled close to the scalp, hair can offer up to nearly a 3-month detection period for alcohol and other drugs. It's easy to collect, challenging to tamper with, and convenient to ship.

A 1.5-inch segment of roughly 200 hair strands (similar in diameter to a #2 pencil) near the scalp provides about 100mg of hair, which is the ideal sample for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be collected. In the context of head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The drug test result laboratory process involves four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a lab’s system. This step confirms the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not provided by an electronic chain of custody system.

Screening conducts a preliminary check for drugs of abuse. While Screening serves as a cost-efficient approach to exclude drug use in most samples, a positive result requires confirmation to be accepted in court. Any samples with a presumptively positive screen necessitate a secondary confirmation.

If a sample registers as presumptively positive during Screening, more hair is retrieved from the initial sample and readied for Extraction. In this phase, drugs are extracted from the hair at a much lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most complex technique to execute.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as needed. The complete lab procedure from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection duration: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which have a briefer detection span.
• Hard to tamper with: Cheating a hair drug test is very difficult, ensuring the results are more reliable.
• Offers historical insights: It provides a timeline of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Elements like hair color and personal hair growth differences can impact the metabolite concentration in the hair.

Note: Although often termed "hair follicle tests", the test analyzes the hair strand itself and not the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests to traditional urine tests in Echo Lake, WA, the advantages become clear. Hair testing offers superior detection accuracy and reliability.

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.
