Hair Follicle Drug Testing - Harrington, WA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and narcotic use by trapping biomarkers within the fibers of growing hair strands. When gathered near the scalp, hair can provide up to roughly a 3-month window for detecting alcohol and narcotics. Hair is easy to collect, somewhat tough to tamper with, and straightforward to ship.

A 1.5-inch section of nearly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal specimen for screening and confirmation. For EtG, add-ons, and/or procedures beyond 10 panels, 150mg of the sample is suggested. It's recommended to measure the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent volume of body hair can be gathered. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary steps involved in the laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample into a laboratory's framework. This step involves confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not accounted for by an electronic chain of custody system.

Screening entails an initial, rapid assessment for drugs of abuse. While Screening is an economical way to eliminate drug use on most samples, a positive screen needs to be confirmed for it to be court-admissible. Any samples that yield a presumptive positive during Screening require a secondary confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the initial sample and prepared for Extraction. In this stage, drugs are extracted from hair at substantially lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleaned as needed before confirmation. The entire laboratory process from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, in contrast with urine tests that have a shorter detection period.
• Hard to cheat: It is very challenging to manipulate a hair drug test, thus ensuring more reliable results.
• Offers historical information: It can reveal a pattern of drug consumption over time, rather than just recent usage.

Limitations:

• Cannot identify recent consumption: It takes roughly 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are typically pricier than other drug testing techniques.
• Result variations: Factors like hair color and individual differences in hair growth can impact the drug metabolite concentration in the hair.

Note: While often called "hair follicle tests", the procedure actually analyzes the hair strand, not the follicle beneath 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.
