Hair Follicle Drug Testing - Vernon, VT

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol consumption. Hair captures a prolonged timeline of drug and alcohol use by encasing biomarkers within the strands as hair grows. When sampled near the scalp, it can offer up to a three-month window for detecting drugs and alcohol. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.

A sample of 1.5 inches consisting of around 200 hair strands (similar in size to a #2 pencil) from the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG evaluations, additional tests, or panels exceeding 10, a 150mg amount of the sample is advised. It is recommended to measure the sample on a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair is an alternative. Head hair exclusively refers to scalp hair, while body hair includes other types of hair (facial, axillary, etc.).

Process Overview

The drug testing process in a lab follows four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial phase of incorporating a sample into the lab’s system. This step involves ensuring the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and entering any extra data not available electronically via the chain of custody system.

Screening provides an initial, swift analysis for drugs. While it is a cost-efficient method to eliminate drug presence in most samples, a positive screening result must be verified to be legally valid. Samples showing a presumptive positive in Screening demand further confirmation.

Should a sample show presumptive positivity at the Screening stage, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening notably complex.

For any positive Screening outcomes, Confirmation is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked presumptive positive undergo a wash before Confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated 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 duration: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests, which have a shorter detection period.
• Resistance to tampering: It is significantly challenging to falsify a hair drug test, enhancing result accuracy.
• Shows usage history: It reveals a pattern of drug consumption over an extended period, not just recent activity.

Limitations:

• Inability to detect recent consumption: It typically takes around 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variation: Variables such as hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Though often termed as "hair follicle tests," the examination assesses the hair strand itself, not the follicle underneath 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.
