Hair Follicle Drug Testing - Cumberland, WA

What it is, How it works

Hair analysis has become recognized as a significant method for identifying drug and alcohol consumption. Hair captures a long-term timeline of alcohol and other substances by encapsulating biomarkers within the fibers of its strands. When obtained near the scalp, hair can offer a detection range of up to roughly three months for alcohol and other substances. Hair is straightforward to collect, relatively resistant to tampering, and convenient to transport.

A 1.5-inch segment comprising roughly 200 hair strands (comparable in size to a #2 pencil) proximal to the scalp yields 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional components, and/or assessments exceeding 10 panels, 150mg of the specimen is advised. We suggest measuring the specimen with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may substitute. When discussing head hair, it references only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initially processing a sample into a laboratory's system. It consists of confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.

Screening implies an initial swift assessment for drugs of abuse. While Screening serves as a cost-effective method to rule out drug use in most samples, a positive screen demands confirmation for court admissibility. Any samples showing presumptive positivity in Screening indeed require a secondary confirmation.

If a sample appears presumptively positive during the Screening phase, additional hair is sourced from the initial specimen and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), presenting hair drug screening as the most challenging methodology to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, whereas urine tests possess a shorter detection period.
• Challenging to cheat: It is quite challenging to cheat on a hair drug test, enhancing result accuracy.
• Offers historical insights: It can exhibit a drug use pattern across an extended time frame, not merely recent usage.

Limitations:

• Cannot identify recent usage: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests cost more than alternative drug testing techniques.
• Result variations: Factors like hair color and individual differences in hair growth can affect drug metabolite concentration within the hair.

Note: While frequently termed as "hair follicle tests", the test itself analyses the hair strand rather than the hair 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.
