Hair Follicle Drug Testing - Arp, TX

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol usage. The hair shaft captures a prolonged timeline of substance use by embedding biomarkers within the strands of hair as it grows. When sampled near the scalp, it can reveal use for a span of up to three months for drugs and alcohol. Hair is straightforward to gather, somewhat resistant to tampering, and easy to transport.

An ideal sample would consist of a 1.5-inch length containing around 200 hair strands (resembling the thickness of a #2 pencil) closest to the scalp, which provides 100mg of hair suitable for testing and verification. For EtG, supplemental tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample using a jeweler’s scale. In cases where scalp hair is not available, an equivalent amount of body hair may be used. When talking about head hair, we mean exclusively scalp hair. Body hair encompasses other types, such as facial, axillary, etc.

Process Overview

The procedure for analyzing drug test results in a lab involves these four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into the lab's system. This step includes ensuring the sample's proper sealing and shipment, providing a random LAN (Laboratory Accessioning Number), and completing any further data entries not available in an electronic chain of custody.

Screening entails an initial assessment for drug misuse. Though Screening offers a low-cost solution to exclude drug exposure for most samples, any positive results from screening should be confirmed to validate them for legal proceedings. Those samples flagged as presumptively positive during Screening require another confirmation.

In cases where Screening indicates a positive result, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at relatively lower concentrations than other methods (e.g., urine or oral fluid), illustrating why hair drug analysis stands as the most intricate procedure to execute.

Positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples initially marked as presumptive positive are cleansed before confirmation. The comprehensive lab analysis, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO/IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection period: Hair tests can uncover drug intake for as long as 90 days, in contrast to urine tests that have shorter detection times.
• Hard to manipulate: Hair drug analysis is challenging to subvert, ensuring more reliable results.
• Offers historical context: This method can map out drug consumption over time, not merely recent use.

Drawbacks:

• Inability to detect recent consumption: Drugs become apparent in hair roughly 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing techniques.
• Result variability: Factors such as hair color and individual hair growth rates might influence the concentration of drug residues in the hair.

Note: Although widely known as "hair follicle tests," the analysis focuses on the hair shaft and not the follicle beneath the skin.

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.
