Hair Follicle Drug Testing - Toca, LA

What it is, How it works

Hair testing is increasingly recognized as an effective means to identify drug and alcohol consumption. Hair offers a comprehensive account of alcohol and drug use by capturing biomarkers within the strands as they grow. Collecting hair near the scalp allows for up to a 3-month detection period for alcohol and various drugs. It's easy to gather, moderately difficult to tamper with, and conveniently shipped.

Securing a 1.5-inch sample from about 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg—the optimal quantity for testing and validation. For EtG, add-ons, and tests exceeding 10 panels, 150mg is advised. Employ a jeweler's scale to measure the sample weight. If scalp hair isn't accessible, an equivalent volume of body hair can be gathered. Mentioning head hair pertains solely to scalp hair, while body hair encompasses facial, axillary, and other types.

Process Overview

The key stages in the laboratory analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the laboratory processing of a sample. This step ensures the sample's proper sealing and dispatch, assigns a LAN (Laboratory Accessioning Number), and concludes additional data storage when not facilitated by an electronic custody chain.

Screening offers an initial rapid assessment for drug presence. Although cost-efficient in excluding drug use for most samples, positive results necessitate confirmation for legal validity. Samples presumed positive during Screening need further verification.

Should a sample show presumptive positivity in Screening, more hair is extracted from the initial batch and set for Extraction. This phase retrieves drugs from hair at much-reduced concentrations compared to other methods like urine or oral fluid, rendering hair drug screening challenging yet accurate.

GC/MS, GC/MS/MS or LC/MS/MS techniques perform Confirmation for positive screenings. Necessary washes precede the confirmation of all presumptively positive samples. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can trace drug use up to 90 days, while urine tests present a shorter timeframe.
• Test integrity: Cheating a hair drug test is highly challenging, thus ensuring result precision.
• Historical insights: Offers a drug use timeline over months, not limited to recent usage.

Limitations:

• Delayed detection: Drugs require 5-7 days to be traceable in hair.
• Expense: Hair drug tests typically cost more than alternative testing methods.
• Result variability: Hair color and individual growth differences can impact drug metabolite concentrations.

Note: Commonly termed "hair follicle tests," the evaluation focuses on the strands rather than 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
