Hair Follicle Drug Testing - Trinidad, CA

What it is, How it works

The utilization of hair testing has emerged as a robust instrument for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair offers a comprehensive history of alcohol and other substance use. When gathered near the scalp, hair can reveal evidence of alcohol and drug presence within an approximate three-month detection timeframe. The collection process for hair is straightforward, resistant to adulteration, and convenient to transport.

A sample measuring 1.5 inches from around 200 strands of hair (roughly the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is optimal for screening and confirmation purposes. For EtG, additional tests, or panels exceeding 10, a specimen quantity of 150mg is advisable. We suggest weighing the specimens using a jeweler’s scale. In instances where scalp hair is unavailable, an equivalent volume of body hair can be collected. Reference to head hair exclusively pertains to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning process entails the initial integration of a sample into the laboratory’s system. This process includes confirming the sample was appropriately sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not available via an electronic chain of custody system.

Screening offers a preliminary assessment for substance abuse. Whereas screening offers an economical means to dismiss drug use for the vast majority of samples, a positive result from screening necessitates confirmation to be recognized in a legal setting. Any samples yielding a presumptive positive outcome during Screening require subsequent confirmation.

For samples exhibiting presumptive positive results during the Screening phase, additional hair is extracted for the Extraction phase. During this phase, drugs are withdrawn from hair at significantly lower concentrations than possible through alternative methods (such as urine or oral fluid), establishing hair drug testing as one of the most challenging methodologies to execute.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positive outcomes are cleansed prior to confirmation as warranted. From Accessioning through Confirmation, the entire laboratory workflow adheres to the CAP (College of American Pathologists) Hair standards and accreditation under ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace substance use over a timeline extending to 90 days, contrasting with urine tests that offer a reduced detection period.
• Increased resistance to tampering: Due to the difficulty in manipulating hair drug tests, the results are deemed more reliable.
• Chronological usage records: It facilitates insights into patterns of substance consumption over time, rather than focusing solely on recent use.

Limitations:

• Inability to capture recent usage: Detection of substances in hair necessitates approximately 5-7 days.
• Price considerations: Compared to alternative drug testing methods, hair drug assessments typically incur higher expenses.
• Result inconsistencies: Variables such as hair color and individual hair growth differences can influence the concentrations of drug metabolites within hair.

Clarification: Although frequently termed as "hair follicle tests", the assessment process examines the hair strand and not 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.
