Hair Follicle Drug Testing - Woodstock, IL

What it is, How it works

Hair examinations have emerged as a vital method for uncovering drug and alcohol consumption. Hair serves as a chronicle for drug and alcohol use, capturing biomarkers within the strands of the growing hair. Collecting hair proximal to the scalp offers a detection range of nearly 90 days for substances. It is straightforward to collect, relatively resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, composed of roughly 200 hair strands (around the thickness of a pencil), closest to the scalp, yields 100mg of hair, the optimum quantity for analysis and verification. For EtG, supplementary tests, or panels exceeding 10, 150mg of the sample is advisable. Using a jeweler’s scale for specimen measurement is suggested. In the absence of scalp hair, an equivalent quantity of body hair may be utilized. Reference to head hair pertains strictly to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test outcomes is characterized by four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary incorporation of a sample into a laboratory framework. This process involves confirming the sample’s secure seal and proper shipping, generating a random LAN (Laboratory Accessioning Number), and completing additional data entry if an electronic chain of custody system doesn’t provide it.

Screening entails an initial expeditious assessment for substance abuse. Although Screening is an economical approach to eliminate drug use in most cases, a positive screen necessitates confirmation to hold up in legal settings. Confirming presumptively positive Screening samples is requisite.

When a sample tests positive in the Screening phase, further hair is extracted from the original specimen for Extraction. At this stage, drugs are isolated from hair at concentrations far lower than those found in other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex testing method.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to confirm any positive results from the screening. Any samples presumed to be positive are cleansed prior to their confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation undergoes evaluation under the watch of CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair tests can signal drug usage for up to 90 days, contrasting with urine tests which have briefer detection periods.
• Hard to deceive: Cheating a hair test is very challenging, enhancing the accuracy of the results.
• Shows historical trends: Hair testing reveals patterns of drug use over an extended duration, rather than just recent usage.

Limitations:

• Inability to detect recent consumption: Detection in hair requires approximately 5-7 days for drugs to register in hair.
• Expense: Generally, hair tests are pricier compared to other drug testing techniques.
• Diversity in outcomes: Differences such as hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests", the analysis targets the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing surpasses urine testing in detection accuracy and reliability in Woodstock, IL. Superior detection accuracy captures a longer history of substance use, while urine tests cover a shorter timeframe.

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.
