Hair Follicle Drug Testing - Yeoman, IN

What it is, How it works

Hair testing has been recognized as an effective tool for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of a growing hair strand. Collecting hair near the scalp can yield about a 3-month window for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch portion of around 200 hair strands (similar to the thickness of a #2 pencil) close to the scalp yields 100mg of hair, which constitutes the optimal sample for screening and confirmation. For EtG, additional tests, and/or tests above 10 panels, 150mg of the specimen is advisable. We advocate for weighing the specimen on a jeweler’s scale. If scalp hair is unavailable, an equal volume of body hair can be collected. When referring to head hair, we are exclusively mentioning scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four core steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial introduction of a sample into a laboratory’s system. This process includes confirming that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening provides an initial quick assessment for drugs of abuse. While Screening is a cost-efficient method to eliminate drug usage on the majority of samples, a positive screen must be substantiated to be admissible in court. Any samples that are presumptively positive in Screening necessitate a secondary confirmation.

If a sample is presumptively positive in the Screening phase, more hair is extracted from the original specimen and prepped for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to undertake.

Any positive screening result is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo a wash prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection window.
• Challenge to cheat: Cheating a hair drug test is highly difficult, enhancing the accuracy of results.
• Delivers historical data: It can depict a pattern of drug use over a time frame, rather than just recent use.

Limitations:

• Inability to detect recent use: It takes approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are generally more costly than other drug testing methods.
• Result variations: Factors such as hair color and personal variations in hair growth can affect the concentration of drug metabolites in hair.

Note: Although frequently referred to as "hair follicle tests", the test itself examines the hair strand, not the hair 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.
