Hair Follicle Drug Testing - Van Vleck, TX

What it is, How it works

Hair testing is now recognized as an effective means for detecting the use of drugs and alcohol. Hair captures a long-term profile of drugs and alcohol by capturing biomarkers within the fibers of the extending hair strand. When obtained near the scalp, hair can offer up to roughly a 3-month detection timeframe for drugs and alcohol. Hair is straightforward to gather, relatively challenging to tamper with, and simple to mail.

A 1.5-inch section containing around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, optional additions, and/or testing beyond 10 panels, 150mg of the sample is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair can be used. In the context of head hair, we exclusively mean scalp hair. Body hair includes all other hair varieties (facial, axillary, among others).

Process Overview

The four key phases in the laboratory analysis of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the primary processing of a specimen entering a laboratory’s system. This phase involves checking that the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening entails an initial rapid evaluation for substances of abuse. Despite being a cost-effective method to exclude drug usage in most samples, a positive screen requires confirmation to be valid in legal settings. Presumptively positive Screening samples necessitate further confirmation.

If the Screening phase results are presumptively positive, additional hair is extracted from the initial sample and prepped for Extraction. In this stage, substances are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which positions hair drug screening as the most challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS tools conduct the Confirmation of any positive screening outcome. All presumptive positive specimens undergo a washing process before Confirmation if necessary. The entire laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, contrasting with urine tests with shorter detection periods.
• Testing integrity: It is challenging to compromise a hair drug test, enhancing result accuracy.
• Historical usage data: It reveals a pattern of drug usage over time, not solely recent use.

Limitations:

• Misses recent use: Drugs are detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs than other drug testing techniques.
• Result variability: Elements like hair color and individual hair growth differences can influence the concentration of drug residues in hair.

Note: While frequently termed "hair follicle tests", the test itself examines the hair strand, not the scalp-embedded hair 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.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
