Hair Follicle Drug Testing - Westwood Shores, TX

What it is, How it works

The utility of hair testing as a tool for alcohol and drug detection is widely acknowledged. The composition of hair allows it to capture biomarkers over an extended timeframe, offering a historical account of substance use. When hair samples are taken near the scalp, they can reflect usage patterns up to a span of roughly three months. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

To acquire a 100mg sample for optimal analysis, a 1.5-inch portion consisting of roughly 200 hair strands (equivalent to the diameter of a #2 pencil) taken closest to the scalp is needed. For comprehensive tests such as EtG or those exceeding 10 panels, a 150mg sample is advised. The precise weight of the specimen should be measured with a jeweler’s scale. Should scalp hair be unavailable, an equivalent mass of body hair is acceptable. Specifically, "scalp hair" refers solely to hair on the head, whereas "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for processing drug test results involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially introduced into the laboratory system. This phase ensures that the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. Although it is a cost-effective screening method for excluding drug use on most samples, a confirmed test is required for legal proceedings. Samples that test presumptively positive during Screening necessitate further confirmation.

For samples flagged as presumptively positive during Screening, more hair is extracted from the original sample and readied for the Extraction phase. During Extraction, drug compounds are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which accounts for the complexity of hair drug screening.

Confirmation for any positive screenings is completed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Before Confirmation, all presumptive positive samples are cleansed as required. The complete laboratory flow from Accessioning to Confirmation undergoes evaluation in line with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can determine drug use up to 90 days back, unlike urine tests with a more limited timeframe.
• Hard to deceive: Cheating a hair drug test is extremely challenging, thus enhancing result reliability.
• Offers historical insights: It documents a pattern of drug consumption over time, not merely recent use.

Limitations:

• Cannot spot recent consumption: It takes about 5-7 days before drugs become traceable in hair.
• Expense: Hair drug tests generally incur higher costs than other testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth may influence drug metabolite concentrations in hair.

Note: Although frequently dubbed "hair follicle tests", the assessment actually focuses on 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.
