Hair Follicle Drug Testing - Cecilton, MD

What it is, How it works

Hair analysis is widely recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance intake by embedding biomarkers within the hair strand as it grows. When sampled near the scalp, hair can reveal drug or alcohol use within an approximate 3-month timeframe. It's straightforward to collect, challenging to tamper with, and easy to transport.

A 1.5-inch section consisting of around 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, enhancements, or testing beyond 10 panels, 150mg of the sample is advised. It's suggested to determine the sample's weight using a jeweler's scale. If scalp hair is not accessible, 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 primary steps in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with integrating a sample into a lab's system initially. This step ensures the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic chain of custody system.

Screening provides an initial, rapid evaluation for drug substances. Although Screening is a cost-efficient method to exclude drug presence in most samples, a positive result must be validated for legal acceptability. Samples with presumptive positives during Screening necessitate further confirmation.

Should a sample be presumptively positive in Screening, additional hair is taken from the original sample and readied for Extraction. During this phase, drugs are retrieved from hair at a much reduced concentration compared to other methods (such as urine or oral fluid), which is why hair drug testing is considered the most complex method.

Any positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumed positive samples undergo cleaning as needed. The complete laboratory procedure from Accessioning to Confirmation is assessed according to CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can trace drug use up to 90 days, unlike urine tests which have a narrower detection timeframe.
• Hard to evade: Cheating on a hair drug test is exceedingly difficult, enhancing result accuracy.
• Offers historical insights: It can illustrate a drug usage trend over time, not merely recent usage.

Limitations:

• Inability to identify recent use: Roughly 5-7 days are required for drugs to become discernible in hair.
• Expense: Hair drug tests are typically pricier than alternative drug testing techniques.
• Result inconsistency: Variables like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the procedure actually examines the hair strand, not the underlying hair follicle.

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.
