Hair Follicle Drug Testing - Livonia, LA

What it is, How it works

Hair testing is widely recognized as a robust method for identifying drug and alcohol usage. Hair retains a long-term record of alcohol and drug exposure by embedding biomarkers within the strands of growing hair. By sampling hair near the scalp, one can achieve up to a three-month window of detection for both alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and simplifies transportation.

A 1.5-inch segment consisting of approximately 200 hairs (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for initial screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, it is advised to collect 150mg of hair. Using a jeweler’s scale to weigh the sample is advisable. If scalp hair is not available, an equivalent quantity of body hair is permissible. When discussing head hair, this refers exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The process involves four key steps in the lab processing of a drug test result, namely Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the primary process of integrating a sample into the lab's system occurs. This phase verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes other necessary data entry absent from an electronic chain of custody system.

Screening serves as an initial rapid assessment for drugs of abuse. Though Screening is a cost-efficient approach to eliminate drug use likelihood in most samples, a positive screen necessitates confirmation for legal admissibility. Presumptively positive samples require a subsequent confirmation procedure.

If a sample preliminarily tests positive at the Screening phase, more hair is extracted from the original sample and readied for Extraction. In this step, drugs are removed from hair at concentrations lower than other methods (e.g., urine or oral fluid), rendering hair drug screening the most intricate method to execute.

Positive screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo preconfirmation washing as necessary. The entirety of the laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug usage for up to 90 days, whereas urine tests provide a shorter detection window.
• Difficulty to cheat: Hair drug testing is challenging to compromise, resulting in higher accuracy.
• Provides historical data: It depicts a substance use pattern over time, beyond recent consumption.

Limitations:

• Cannot detect recent use: There’s an approximate 5-7 day period before drugs become traceable in hair.
• Cost: Comparatively, hair drug tests are pricier than other testing techniques.
• Variations in results: Elements such as hair color and individual hair growth disparities can influence drug metabolite levels within hair.

Note: Although termed as "hair follicle tests," the analysis actually examines the hair itself and not the underlying follicle.

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.
