Hair Follicle Drug Testing - Clinchco, VA

What it is, How it works

Hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair can capture a detailed history of substances by embedding biomarkers within its fibers as it grows. When obtained near the scalp, hair can reveal alcohol and drug use over a span of around three months. It is easy to collect, relatively resistant to tampering, and straightforward to transport.

Obtaining a 1.5-inch section of about 200 hair strands (roughly the width of a #2 pencil), closest to the scalp, provides 100mg of hair, the recommended amount for both screening and validation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of hair is advised. Using a jeweler’s scale, we recommend weighing the hair sample. If scalp hair is unavailable, a comparable quantity of body hair can be used. "Head hair" refers solely to scalp hair, while "body hair" includes other types (like facial, axillary, etc.).

Process Overview

There are four essential steps in the laboratory drug test procedure: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial input of a sample into a laboratory system. This step ensures the sample is properly sealed, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody.

During Screening, there’s a preliminary examination for substance use. Although Screening offers a cost-effective means to dismiss drug use in most samples, a conclusive result is necessary for legal admissibility. Any samples with a presumptive positive in Screening need second-phase confirmation.

Should a sample show a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, substances are drawn from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), making hair drug detection particularly challenging.

Confirmation of any positive screen is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any samples with presumptive positives undergo a wash if necessary. The entire procedure from Accessioning to Confirmation adheres to CAP (College of American Pathologists) standards using the Hair designation and maintains ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug testing can track drug use for up to 90 days, exceeding the shorter timeframe of urine tests.
• Challenging to manipulate: Hair drug testing is difficult to manipulate, enhancing result accuracy.
• Tracks historical usage: It reveals drug use patterns across time, not just recent intake.

Limitations:

• Cannot detect recent use: A period of 5-7 days is required for drugs to be detectable in hair.
• Expense: Hair drug tests are typically costlier than alternative testing methods.
• Result variability: Variables like hair color and individual hair growth can influence the detected concentration of drug metabolites.

Note: Commonly called "hair follicle tests", this test analyzes the hair itself, 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.
