Hair Follicle Drug Testing - Derby Line, VT

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol usage. The hair retains a long-term account of alcohol and other substances by encapsulating biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can offer a detection timeframe for alcohol and other drugs that extends to roughly 3 months. Hair is straightforward to gather, not easily tampered with, and convenient to transport.

A sample measuring 1.5 inches, with around 200 hair strands (akin to the size of a #2 pencil) closest to the scalp, yields 100mg of hair, which is the ideal sample size for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. It is best to weigh the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair may be used. References to head hair pertain specifically to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

During Accessioning, the process begins with integrating a sample into a laboratory’s workflow. This process verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and involves completing any additional data entry required that was not provided by an electronic chain of custody system.

Screening involves conducting an initial rapid examination for substances of abuse. While Screening is an economical method to exclude drug use in most samples, a positive screening result requires confirmation to be admissible in legal proceedings. Any samples with a presumptive positive result in Screening necessitate further confirmation.

Should a sample exhibit a presumptive positive in Screening, more hair is extracted from the initial sample and prepared for Extraction. In this stage, drugs are extracted from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), hence hair drug screening poses the greatest challenge in execution.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed before Confirmation as needed. The entire laboratory process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and accredited in compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify drug use for as long as 90 days, compared to urine tests with a shorter detection period.
• Challenging to deceive: Hair drug tests are difficult to falsify, enhancing result precision.
• Provides usage history: The test illustrates a pattern of drug usage over time, not merely recent consumption.

Limitations:

• Cannot identify recent usage: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variations: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the examination evaluates the hair strand and 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.
