Hair Follicle Drug Testing - Maplehurst, WI

What it is, How it works

Hair analysis has emerged as an effective method for uncovering alcohol and drug consumption. Hair captures a prolonged record of alcohol and substances by embedding biomarkers within the growing strand's fibers. When taken near the scalp, it can reveal usage over a span of roughly three months. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A sample measuring 1.5 inches, comprising around 200 strands (resembling a #2 pencil's size) near the scalp yields 100mg, the optimal quantity for screening and confirmation. A 150mg sample is advised for EtG, supplementary analysis, or when testing beyond 10 panels. It's best to use a jeweler’s scale for measuring the sample. If scalp hair isn't available, an equivalent measure of body hair can be used. References to head hair specifically mean scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning marks the first stage, where a sample is logged into a lab's system. This involves ensuring that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data entry if electronic custody documentation is incomplete.

Screening is a preliminary rapid assessment for drug abuse. While economical for excluding drug use in most samples, any positive results in this phase require validation to be court-acceptable. Any presumptively positive screens need a further confirmation step.

For any presumptively positive findings in Screening, additional hair is extracted from the initial sample for Extraction. At this stage, substances are extracted from hair at significantly lower concentrations than other tests (such as urine or oral fluids), making hair drug testing a particularly challenging technique.

Confirmation of any positive screen results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples are cleansed as necessary prior to confirmation testing. The entire testing process from Accessioning through Confirmation is examined under the CAP (College of American Pathologists) Hair designation and in line with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Drug use is detectable in hair for up to 90 days, as opposed to urine tests with shorter detection durations.
• Reduced likelihood of evasion: Cheating a hair drug test is very difficult, resulting in more accurate findings.
• Offers historical insights: Drug use patterns are revealed over time, not limited to recent activity.

Limitations:

• Incapable of detecting recent usage: It takes about 5-7 days before drugs are traceable in hair.
• Expense: Hair tests tend to be costlier than other drug testing methods.
• Variability: Differences such as hair color and individual growth rates can influence detected drug metabolite levels.

Note: Regarded frequently as "hair follicle tests," the analysis is performed on the hair strand, not on the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
