Hair Follicle Drug Testing - Romoland, CA

What it is, How it works

Hair testing is recognized as an effective means for detecting drug and alcohol consumption. By embedding biomarkers within the growing hair strands, hair offers a comprehensive history of alcohol and drug use. When cut close to the scalp, hair delivers a detection timeframe of approximately three months for both alcohol and drugs. Collecting hair is straightforward, comparatively hard to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for analysis and validation. For testing such as EtG, additional testing, and/or analyses exceeding 10 panels, 150mg of the sample is advised. We propose measuring the sample using a jeweler’s scale. If scalp hair isn't accessible, an equal portion of body hair can be used. The term head hair specifically pertains to scalp hair alone. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial processing within a laboratory's framework. This process ensures proper sealing and dispatch of the sample, assigns it a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.

Screening provides an initial swift assessment for drug abuse. While Screening is a budget-friendly means to eliminate drug usage for most samples, any positive screen requires confirmation for legal admissibility. Presumptive positive samples in Screening necessitate a follow-up confirmation.

If Screening indicates a presumptive positive, more hair is extracted from the main specimen for Extraction preparation. Here, drugs are isolated from hair at a noticeably lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most intricate methodology to undertake.

Confirmation of any positive screening findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every sample with a presumptive positive is cleaned before confirmation as necessary. The entire process from Accessioning to Confirmation upholds standards guided by 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 trace drug use up to 90 days, unlike urine tests which offer a shorter detection window.
• Difficulty in tampering: Cheating a hair drug test is significantly challenging, enhancing result accuracy.
• Traces usage patterns: It can depict a timeline of drug consumption over time, not merely recent use.

Limitations:

• Inability to trace recent use: Detecting drugs in hair takes roughly 5-7 days.
• Expense: Hair drug tests generally have a higher cost than other drug test methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence the presence of drug metabolites in hair.

Note: Often referred to as "hair follicle tests", the analysis actually examines the hair strand and excludes 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. 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.
