Hair Follicle Drug Testing - Lake Riverside, CA

What it is, How it works

Hair testing is increasingly recognized as an effective means of identifying drug and alcohol consumption. By embedding biomarkers within the fibers of hair strands as they grow, hair offers a comprehensive historical record of substance use. Collected from near the scalp, hair can reveal a detection period of up to three months for both alcohol and drugs. The collection process is straightforward, challenging to tamper with, and easy to transport.

When collecting a 1.5-inch sample of approximately 200 strands (roughly the width of a #2 pencil) from the scalp, it provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional analyses, or tests beyond 10 panels, 150mg of the sample should be used, and weighing the sample with a jeweler’s scale is advised. In the absence of scalp hair, an equivalent amount of body hair can be used. Head hair refers solely to scalp hair, while body hair encompasses other types (e.g., facial, axillary).

Process Overview

The laboratory process for drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into a lab's system, confirming correct sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not handled by electronic chain of custody systems.

Screening provides an initial scan for substances of abuse. Although cost-effective for negating drug usage in most samples, a positive screen necessitates confirmation to be legally valid. Samples returning a presumptive positive require further confirmation.

In cases of presumptive positives during Screening, additional hair from the initial sample is used for Extraction. During this phase, drugs are removed from hair at lower concentrations than other methods (e.g., urine or oral fluid), hence making hair drug testing a complex procedure.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to confirm any presumptive positive screens. Presumptive positive samples undergo washing before confirmation if required. The comprehensive processing—from Accessioning to Confirmation—is evaluated under CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can register drug use extending up to 90 days, unlike urine tests which offer a reduced detection range.
• Resistance to cheating: Hair drug tests are notably hard to deceive, ensuring higher accuracy of outcomes.
• Traces historical use: This test can delineate a usage pattern over time, rather than just capturing recent activity.

Limitations:

• Delayed detection of recent usage: Drugs are only detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing tends to be more costly relative to other testing methods.
• Result variability: Influencing factors, such as hair color and individual growth rates, can alter drug metabolite concentrations within hair.

Note: Frequently termed as "hair follicle tests", the analysis is conducted on the hair strand itself, 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.
