Hair Follicle Drug Testing - Scotland, CA

What it is, How it works

Hair testing is now recognized as a potent method for identifying drug and alcohol consumption. It offers a comprehensive history of substance use by encapsulating biomarkers within the fibers of the growing hair strand. Hair samples taken near the scalp may reveal a detection timeline of up to three months for alcohol and other substances. Collection is straightforward, tampering is fairly challenging, and shipping is uncomplicated.

A sample measuring 1.5 inches with roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp yields 100mg of hair, the preferred quantity for both screening and confirmation. For additional EtG testing, add-ons, or testing beyond 10 panels, a 150mg specimen is suggested. Use a jeweler's scale for weighing the specimen. If scalp hair is not available, an equivalent amount of body hair can be used. When mentioning head hair, we mean scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four vital phases in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab’s database. This stage includes ensuring the sample was sealed and shipped properly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any outstanding data entry not covered by an electronic custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. While Screening is an economical approach for excluding drug usage in most samples, a positive result requires confirmation to be court-admissible. Samples showing potential positivity in Screening need a secondary verification.

If a sample appears positive during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at notably lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing the most intricate method to execute.

Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is supervised under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, contrasting with urine tests that offer shorter detection periods.
• Challenging to falsify: Faking results in a hair drug test is quite difficult, enhancing result precision.
• Historical data provision: It offers a drug use pattern over an extended timeframe, not just recent usage.

Limitations:

• Inability to detect recent use: Drugs typically require about 5-7 days before becoming detectable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing methods.
• Result variability: Variables like hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although often termed "hair follicle tests", the analysis is performed on the hair strand, not the follicle 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.

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.
