Hair Follicle Drug Testing - Mayo, MD

What it is, How it works

Utilizing hair testing is acknowledged as an effective means for identifying drug and alcohol usage. Hair acts as a chronological record of alcohol and drugs by encapsulating biomarkers within the developing hair fibers. When gathered near the scalp, hair offers a detection period of up to three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient for shipping.

A sample of 1.5 inches, consisting of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is ideal for testing and verifying results. For EtG, add-ons, and/or screenings beyond 10 panels, a sample of 150mg is advised. It's recommended to use a jeweler’s scale for measuring the specimen. Should scalp hair be inaccessible, a corresponding volume of body hair may be taken. By head hair, we mean only scalp hair. Body hair pertains to all other hair varieties (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a lab’s system. This step involves confirming that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic chain of custody system.

Screening constitutes an initial rapid check for drug abuse. While Screening is an economical way to eliminate drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Any samples testing positive in Screening require a subsequent confirmation.

If a sample is deemed positive at the Screening phase, additional hair is taken from the original sample for Extraction. During this phase, drugs are extracted from hair at considerably lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are cleansed before confirmation as needed. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Difficult to manipulate: Cheating a hair drug test is highly challenging, increasing result accuracy.
• Historical insight: It offers a historical pattern of drug use over time, not just recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests generally cost more than other drug testing methods.
• Result variability: Elements such as hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the analysis is on the hair strand, not the scalp's 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.

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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
