Hair Follicle Drug Testing - Ascutney, VT

What it is, How it works

Hair testing is increasingly regarded as an effective mechanism for identifying drug and alcohol consumption. Hair acts as a long-term record for alcohol and other substances by embedding biomarkers within the growing hair strand's fibers. When gathered near the scalp, hair can reveal up to a roughly 3-month detection timeframe for alcohol and other drugs. Hair is easy to collect, relatively challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches from approximately 200 hair strands (akin to the width of a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal sample for assessment and validation. For EtG, additions, and/or examinations over 10 panels, 150mg of the sample is suggested. We advise measuring the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair may be gathered. By head hair, we mean only scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The drug test result laboratory processing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample's initial processing in a lab's system. This step includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.

Screening entails a preliminary swift verification for drug abuse. Although Screening is an economical method to exclude drug use for most samples, a positive screen must be verified to be court-admissible. Any samples deemed presumptively positive in Screening need an additional confirmation.

If a sample appears presumptively positive during the Screening phase, more hair is taken from the initial specimen and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is the most challenging technique to execute.

The Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of all presumptive positive samples occurs before confirmation. From Accessioning to Confirmation, the entire laboratory process is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
• Reduced feasibility to cheat: Cheating a hair drug test is extremely tough, resulting in more precise outcomes.
• Provides historical insights: It can outline a drug use pattern over time, not just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs become noticeable in hair after approximately 5-7 days.
• Expense: Generally, hair drug tests are pricier than other drug testing approaches.
• Result variability: Elements like hair color and individual differences in hair growth might influence drug metabolite concentrations in hair.

Note: The test is often termed "hair follicle tests", but it evaluates the hair strand, not the scalp's 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. 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.
