Hair Follicle Drug Testing - Robinson, IL

What it is, How it works

Hair analysis is now recognized as a robust method for identifying drug and alcohol consumption. Hair captures a historical record of substance intake by embedding biomarkers within the strands as they grow. When cut close to the scalp, hair can offer a detection window of up to roughly three months for substances like alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches, comprising approximately 200 hair strands (about the diameter of a #2 pencil) taken nearest to the scalp, yields 100mg of hair, which is optimal for testing and confirmation. For assessments like EtG, additional requests, and/or tests beyond a 10-panel, 150mg of hair is advisable. It is best to weigh the sample using a jeweler’s scale. If hair from the scalp is not obtainable, an equivalent amount of body hair can be provided. References to head hair pertain to scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing stages of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step, which involves entering a sample into a lab's system. This phase includes confirming the sample's proper sealing and delivery, allocating a unique LAN (Laboratory Accessioning Number), and completing extra data input absent in an electronic chain of custody.

Screening serves as a rapid preliminary drug check. Although Screening is a cost-efficient approach for excluding drug usage in most samples, any positive result necessitates confirmation for legal validity. Samples indicating a presumptive positive during Screening demand additional confirmation.

If a sample turns up presumptively positive during the Screening phase, more hair is extracted for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug testing a challenging process to carry out.

Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed pre-confirmation if required. The entire lab procedure from Accessioning to Confirmation is subjected to review under the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests are capable of identifying drug use for up to 90 days, unlike urine tests with limited detection time.
• High difficulty to manipulate: The difficulty in adulterating a hair drug test enhances result accuracy.
• Chronological usage data: It provides a timeline of drug consumption over time, not just recent usage.

Limitations:

• Inability to detect recent ingestion: A period of about 5-7 days is required before drugs become detectable in hair.
• Expense: Hair drug tests generally incur higher costs than other testing techniques.
• Variability in outcomes: Variables like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Despite being commonly called "hair follicle tests", the actual examination involves analyzing the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Robinson, IL, hair follicle testing surpasses urine testing by offering longer detection windows and superior accuracy. While urine tests are limited, hair tests cover up to 90 days, providing a broader view of substance use.

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.
