Hair Follicle Drug Testing - Whitingham, VT

What it is, How it works

Hair tests are recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive timeline of substance intake by capturing biomarkers in the strands of growing hair. Collected near the scalp, it can offer a detection period of up to roughly three months for alcohol and drugs. Hair sampling is straightforward, resistant to tampering, and convenient for shipping.

A hair sample measuring 1.5 inches with around 200 strands (about the width of a #2 pencil) cut close to the scalp provides 100mg of hair, an optimal sample for both screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, 150mg of the specimen is suggested. The use of a jeweler’s scale is recommended for weighing the sample. If scalp hair isn't available, a corresponding amount of body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes entering a sample into the lab’s system. This step ensures the sample was adequately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entry not provided electronically.

Screening serves as a preliminary check for drugs of abuse. Despite its cost-effectiveness for eliminating drug use on most samples, a positive screen requires confirmation for legal admissibility. Samples with presumptive positives in Screening necessitate further confirmation.

If a sample screens presumptively positive, additional hair is extracted from the initial sample for Extraction. This step retrieves drugs from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing a challenging methodology.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is inspected by CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests which offer a shorter detection span.
• Hard to falsify: Cheating on a hair drug test is exceedingly challenging, enhancing result accuracy.
• Historically rich data: It can depict a timeline of drug use over an extended period, not just recent activity.

Limitations:

• Cannot detect immediate use: Drugs become noticeable in hair around 5-7 days post-consumption.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Differences in hair color and personal hair growth rates can impact drug metabolite levels in hair.

Note: Although commonly termed as "hair follicle tests", the analysis targets the hair strand, not the underlying follicle.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Whitingham, VT
Hair follicle testing offers superior detection capabilities compared to traditional urine tests. With the ability to identify drug usage over an extended period, it ensures more accurate and dependable results.

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.
