Hair Follicle Drug Testing - Rochester, IL

What it is, How it works

Hair testing is acknowledged as an effective instrument for detecting drug and alcohol use. Hair gives a long-standing record of alcohol and drug use by capturing biomarkers within the strands of the growing hair. Collecting samples near the scalp can offer an approximately 3-month detection timeline for substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal quantity for assessment and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advised. Using a jeweler's scale is suggested for specimen weighing. In cases where scalp hair is unavailable, an equivalent amount of body hair can be collected. References to head hair specifically mean scalp hair. Body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory system. This involves verifying the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry that might not be covered by an electronic chain of custody system.

Screening entails a preliminary quick check for substances of abuse. While it serves as a cost-efficient means to exclude drug use from most samples, a positive screening result requires confirmation for courtroom validity. Presumptively positive screenings necessitate a secondary confirmation step.

For samples deemed presumptively positive during Screening, more hair is extracted from the collected specimen for the Extraction phase. In this phase, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug testing a challenging methodology.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives undergo washing before confirmation as required. The full laboratory process, spanning from Accessioning to Confirmation, is subject to review under the CAP (College of American Pathologists) Hair designation and compliant with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug testing can identify drug use for up to 90 days, whereas urine tests offer a shorter detection period.
• Difficulty to cheat: The integrity of a hair drug test is hard to compromise, enhancing result accuracy.
• Provides historical data: It presents a drug use pattern over time rather than merely recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Cost: Hair drug tests tend to be costlier compared to other testing approaches.
• Variations in results: Factors like hair color and individual growth rates can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests," the focus is on analyzing the hair strand, 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. 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.
