Hair Follicle Drug Testing - Stowe, VT

What it is, How it works

Hair testing has emerged as a significant method for determining drug and alcohol consumption. By capturing biomarkers in the fibers of the developing hair strand, hair provides an extended-term record of alcohol and drug use. When taken from near the scalp, hair can present a detection window of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample size for both screening and confirmation. For EtG, supplementary analyses, or tests exceeding 10 panels, a specimen of 150mg is advisable. It is recommended that this specimen be weighed using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be utilized. When mentioning head hair, we are specifically referring to scalp hair only. Body hair includes all other types (facial, underarm, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of integrating a sample into a laboratory’s system initially. This phase includes verifying the appropriate sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not included by an electronic chain of custody system.

Screening is an initial swift assessment for drugs of abuse. While Screening offers a cost-efficient method to exclude drug usage in most samples, any positive screen requires confirmation to be considered valid in judicial settings. Samples that give a presumptive positive in Screening must undergo a secondary confirmation.

If a Screening stage indicates a presumptive positive, additional hair is taken from the initial sample for preparation in the Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations than in other methodologies (for instance, urine or oral fluids), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before necessary confirmation. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage up to 90 days, as opposed to urine tests which have a shorter detection timeframe.
• Difficult to falsify: It is incredibly challenging to cheat a hair drug test, enhancing result precision.
• Provides historical insight: It can reflect a pattern of drug use spanning a period of time, rather than just recent consumption.

Limitations:

• Cannot identify recent usage: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more than other drug testing methods.
• Result discrepancies: Factors such as hair color and personal variations in hair growth can impact the concentration of drug metabolites in the hair.

Note: While frequently called "hair follicle tests", the examination itself evaluates the hair strand rather than the hair follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
