Hair Follicle Drug Testing - Waterloo, WI

What it is, How it works

Hair analysis has emerged as a potent means for identifying drug and alcohol consumption. Hair captures a long-term record of intoxicants by embedding biomarkers within the fibers of the lengthening hair shaft. When gathered near the scalp, hair can reveal up to around a 3-month history of alcohol and drug usage. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil in thickness) near the scalp yields 100mg of hair, which is the optimal sample size for assessment and validation. For EtG, additional tests, or tests covering more than 10 panels, a specimen of 150mg is advised. We advocate utilizing a jeweler's scale to measure the sample. If scalp hair is lacking, an equivalent quantity of body hair can be collected. When speaking of head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four core steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary intake of a sample into a laboratory’s framework. This encompasses confirming the proper sealing and transportation of the sample, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data input not furnished by an electronic chain of custody system.

Screening involves an initial rapid assessment for substances of abuse. While Screening offers a cost-efficient method to discount drug use in most samples, any positive findings must be confirmed for legal admissibility. Samples that return presumptive positives in Screening necessitate secondary confirmation.

When a sample yields a presumptive positive during the Screening phase, extra hair is extracted from the initial sample for Extraction. At this phase, drugs are withdrawn from hair at substantially lower concentrations compared to methods like urine or oral fluid, highlighting why hair drug screening is the most laborious methodology to execute.

Confirmation for any positive screening results is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing prior to confirmation if required. The whole lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and in line with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage over a span of 90 days, unlike urine tests which offer a shorter detection timeframe.
• Hard to falsify: Hair drug tests are difficult to manipulate, enhancing result reliability.
• Supplies historical insight: It demonstrates a pattern of drug consumption over time, not just recent usage.

Limitations:

• Inability to detect recent usage: It requires approximately 5-7 days before drugs manifest in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Elements such as hair color and individual growth variations can alter drug metabolite concentration within hair.

Note: Although frequently termed as "hair follicle tests", the analysis examines the hair strand and not the 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.
