Hair Follicle Drug Testing - Phelan, CA

What it is, How it works

The use of hair testing has gained recognition as an effective method for uncovering drug and alcohol consumption. This technique offers an extended record of substance use through the entrapment of biomarkers within the strands of hair as they develop. When hair is gathered near the scalp, it can reveal substance use within roughly the past three months. The process of collecting hair is straightforward, less prone to tampering, and easily manageable for transportation.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the size of a #2 pencil) taken nearest to the scalp, yields 100mg of hair, which is an optimal sample size for both screening and confirmation. For tests such as EtG enhancements or those exceeding 10 panels, a 150mg specimen is advisable. It is suggested to weigh the specimen on a jeweler’s scale. Should scalp hair be inaccessible, body hair in an equivalent measure may be used. Regarding head hair, we specifically mean scalp hair, while body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

The laboratory process of drug testing involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the entry of a sample into the laboratory's system. This stage ensures the sample's proper packaging and shipment, assigns it a unique LAN (Laboratory Accessioning Number), and performs any supplementary data entry not covered by an electronic chain of custody system.

Screening constitutes a preliminary evaluation for drug abuse. While it's a cost-efficient approach for excluding drug use in most cases, a confirmed screen is necessary for legal validity. Presumptive positives in Screening demand further confirmation.

In cases of presumptive positive results in Screening, additional hair is utilized from the specimen and prepped for Extraction. This phase involves isolating drugs from hair at significantly lower concentrations than other methods (such as urine or saliva), which is why hair drug testing is notably complex.

Confirmation of any positive screen outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before proceeding to confirmation if required. The full laboratory workflow from Accessioning to Confirmation receives scrutiny under the CAP (College of American Pathologists) Hair designation as well as compliance with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests uncover drug use for up to 90 days, in contrast to urine tests with their shorter detection periods.
• Challenging to compromise: The integrity of hair drug tests makes it exceedingly difficult to manipulate results.
• Captures historical consumption: It reflects a timeline of drug use, beyond just recent consumption.

Limitations:

• Recent usage detection: Drugs take about 5-7 days before becoming noticeable in hair samples.
• Expense: Hair drug testing typically involves higher costs than alternative testing methods.
• Result variability: Differences in hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although referred to as "hair follicle tests", it is the hair strand that is analyzed, not the follicle below 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.
