Hair Follicle Drug Testing - Cavanaugh, WA

What it is, How it works

Seen as a potent means, hair testing aids in identifying drug and alcohol consumption. Offering a prolonged timeline of substance usage, hair encapsulates biomarkers within its fibers as it grows. When hair is obtained near the scalp, it enables a detection span of around three months for both alcohol and various drugs. The process of collecting hair is straightforward, challenging to tamper with, and convenient for transportation.

Using a 1.5-inch segment with roughly 200 hair strands, akin to the thickness of a #2 pencil next to the scalp, yields 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, and screenings exceeding 10 panels, 150mg is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. Should scalp hair be absent, a comparable quantity of body hair may be taken. The term head hair exclusively refers to scalp hair, while body hair encompasses all other varieties (such as facial, axillary hair, etc.).

Process Overview

The laboratory analysis of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample within a laboratory's framework. This process ensures the sample was correctly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number) autonomously, and finalizes any included data entry absent from an electronic chain of custody system.

Screening provides an initial, swift evaluation for substances of abuse. Even though it is a budget-friendly mode to dismiss drug consumption in a majority of samples, a positive screen demands confirmation to be considered valid in legal circumstances. Any samples showing presumptive positivity during Screening necessitate a follow-up confirmation.

For samples showing presumptive positivity in Screening, more hair is extracted from the primary specimen and readied for Extraction. At this phase, drugs are extracted from the hair at concentrations considerably lower than what is observed in other methodologies (such as urine or oral fluid), underscoring why hair drug testing is the most complex method to carry out.

Confirmation for any positive result in Screening undergoes testing using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed to be positive are washed before confirmation if necessary. From Accessioning through to Confirmation, the complete lab procedure is thoroughly reviewed, adhering to 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 identify drug usage extending up to 90 days, unlike urine tests which detect usage over a shorter timeframe.
• Challenging to subvert: Avoiding a positive hair drug test is highly challenging, thus ensuring more reliable results.
• Delivers historical insights: It provides insights into drug usage patterns over time instead of just indicating recent use.

Limitations:

• Does not identify recent usage: It takes about 5-7 days for drugs to be detectable within the hair.
• Expense: Generally, hair drug tests are pricier than other drug testing methods.
• Result variability: Aspects such as hair color and individual differences in hair growth can influence the levels of drug metabolites present within hair.

Note: Although commonly termed as "hair follicle tests", the test evaluates the hair strand rather than the hair follicle located 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.
