Hair Follicle Drug Testing - Bolton, VT

What it is, How it works

Hair analyses have emerged as an effective means for detecting drug and alcohol usage. Hair offers a comprehensive timeline of alcohol and drug intake, capturing biomarkers in the hair shaft as it grows. When taken from the area near the scalp, a hair sample can reveal drug and alcohol presence over a period of roughly 3 months. Hair collection is straightforward, difficult to tamper with, and convenient for transport.

A 1.5-inch lock of roughly 200 hair strands (comparable to a #2 pencil thickness) nearest the scalp provides around 100mg, which is the optimal quantity for initial screenings and verification. For EtG, more detailed tests, or panels exceeding 10, a 150mg specimen is advised. We suggest using a jeweler’s scale for precise weighing. If scalp hair isn't available, an equivalent volume of body hair can be utilized. References to head hair specifically denote scalp hair. Meanwhile, body hair encompasses all other hair forms (such as facial and axillary hair).

Process Overview

The critical stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves introducing a sample into the lab's system. This process includes checking the sample’s seal and shipping integrity, allocating a random LAN (Laboratory Accessioning Number), and inputting any additional data absent from the electronic chain of custody.

Screening constitutes an initial swift examination for substances of abuse. Although cost-effective for eliminating drug use in most samples, a positive result must be validated to serve as court evidence. All samples with a presumptive positive result in Screening require further confirmation.

Should a specimen yield a presumptive positive at the Screening phase, more hair is prepared from the original sample for Extraction. During this phase, drugs are separated from the hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), positioning hair analysis as the most challenging form of drug screening.

Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Before proceeding to confirmation, presumptive positives are cleaned as necessary. The entire process from Accessioning to Confirmation undergoes evaluation according to CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use up to 90 days, surpassing the shorter window of urine tests.
• High resistance to falsification: Hair drug tests are incredibly challenging to falsify, ensuring result accuracy.
• Patterns of use: Offers insights into past drug use trends, not just recent consumption.

Limitations:

• Inability to identify recent use: It generally takes 5-7 days for drugs to be traceable in hair.
• Expense: Hair testing is typically costlier than other drug screening techniques.
• Result fluctuations: Variables like hair color and individual hair growth rates can influence metabolite concentration in hair.

Note: Called "hair follicle tests", the analysis focuses on the hair shaft rather than 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
