Hair Follicle Drug Testing - Weweantic, MA

What it is, How it works

The use of hair testing has gained recognition as an effective method to identify drug and alcohol use. Hair captures biomarkers within the fibers of the growing hair strand, offering a long-term record of alcohol and other substances. When taken from near the scalp, hair can provide up to a 3-month window for detecting alcohol and drugs. Collecting hair is straightforward, relatively challenging to tamper with, and simple to send.

A sample measuring 1.5 inches, consisting of approximately 200 strands of hair (similar in size to a #2 pencil) close to the scalp, yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale to weigh the specimen is suggested. In the absence of scalp hair, an equivalent quantity of body hair can be used. References to head hair pertain solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning consists of the initial integration of a sample into a laboratory’s system. This phase includes ensuring the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data requirements not supplied by an electronic chain of custody system.

Screening entails an initial rapid evaluation for drugs of abuse. While Screening offers a cost-efficient means of eliminating drug use in most samples, a positive screen must be verified for legal admissibility. Any samples displaying presumptive positives during Screening require secondary confirmation.

In cases where a sample shows a presumptive positive during Screening, additional hair is extracted from the original specimen and prepared for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging methodologies to conduct.

Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a washing process as needed before confirmation. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use for up to 90 days, unlike urine tests, which have a more limited detection span.
• Hard to bypass: Cheating a hair drug test is exceedingly difficult, resulting in more precise outcomes.
• Records past usage: Hair tests can illustrate a pattern of drug consumption over time, not merely recent usage.

Limitations:

• Incapable of detecting recent usage: It generally takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be more costly than other testing methods.
• Result variability: Variables like hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Even though often termed "hair follicle tests", the analysis actually focuses on the hair strand rather than the follicle located 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.
