Hair Follicle Drug Testing - Walla Walla, WA

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair acts as a repository, preserving a drug and alcohol history by capturing biomarkers in the hair strand's fibers. When obtained close to the scalp, hair can provide an approximate 3-month detection timeframe for substances. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for shipping.

A 1.5-inch section containing roughly 200 hair strands (similar in size to a #2 pencil) from near the scalp will yield 100mg of hair, which is optimal for screening and validation. For EtG tests, add-ons, or tests involving more than 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. Note that "head hair" specifically means scalp hair, while "body hair" refers to all other hair types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into a laboratory's system. This step ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not managed by an electronic chain of custody system.

Screening serves as a preliminary drug check. While Screening is a cost-efficient method for ruling out drug use in most samples, a positive result must be confirmed to be valid in legal contexts. Any samples that screen positive require further confirmation.

If a sample screens positive, more hair is extracted from the initial collection and set for Extraction. In this procedure, drugs are isolated from hair at lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Positive screening outcomes are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives undergo washing prior to confirmation when needed. The entire process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug usage for as long as 90 days, unlike urine tests with shorter detection spans.
• Challenging to manipulate: Cheating a hair drug test is particularly challenging, enhancing result reliability.
• Historical insight: It provides a long-term perspective on drug use habits, beyond recent consumption.

Limitations:

• Delayed detection of recent use: Drugs are not detectable in hair for approximately 5-7 days post-consumption.
• Higher cost: Hair drug testing tends to be more expensive than other drug testing approaches.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Though often called "hair follicle tests," the actual test analyzes 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.
