Hair Follicle Drug Testing - Thalia, TX

What it is, How it works

The practice of hair testing has emerged as a vital method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within its growing fibers. When hair is collected near the scalp, it can reveal drug and alcohol use for up to roughly three months. The collection process is straightforward, the sample is fairly tamper-resistant, and it is straightforward to transport.

To obtain a suitable sample for analysis and verification, a 1.5-inch segment comprising around 200 hair strands (around the thickness of a #2 pencil) from near the scalp yields 100mg of hair. For EtG, additional substances, or tests exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler's scale to weigh the sample. If head hair is not available, an equivalent amount of body hair may be collected. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The drug testing in laboratories involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the introductory step of logging a sample into the laboratory’s system. This process ensures the sample's sealing and shipment were proper, assigns a Laboratory Accessioning Number (LAN) randomly, and finalizes any missing data not covered by an electronic chain of custody.

Screening entails a preliminary inspection for illicit drugs. While Screening is a cost-efficient approach to exclude drug use in most samples, a positive finding must be validated for legal admissibility. Any samples with presumptive positives require further confirmation.

When a sample tests presumptively positive at the Screening phase, additional hair is collected from the initial sample for Extraction. Drugs are extracted from hair at reduced concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing more complex.

Any positive findings from the screening must be confirmed through GC/MS, GC/MS/MS, or LC/MS/MS processes. Presumptive positive samples are cleaned before confirmation as necessary. The comprehensive examination from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair tests detect drug use for up to 90 days, surpassing the shorter window of urine tests.
• Challenges of manipulation: Overcoming a hair drug test is challenging, ensuring more reliable outcomes.
• Tracks use history: It can depict drug usage patterns over time rather than merely recent usage.

Limitations:

• Inability to detect recent usage: Detectability in hair takes approximately 5-7 days post-consumption.
• Expense: Hair tests often incur higher costs than other drug testing techniques.
• Result variability: Factors like hair color and personal hair growth variations can impact drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the assessment actually analyzes the hair shaft, 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.
