Hair Follicle Drug Testing - East Galesburg, IL

What it is, How it works

Testing hair is now recognized as a significant method for detecting substance use. Hair captures a detailed timeline of drug and alcohol usage by embedding biomarkers within its fibers as it grows. When hair is taken from near the scalp, it can reveal a detection period of up to roughly 90 days for substances. Hair is easy to gather, somewhat resistant to tampering, and straightforward to transport.

A sample of 1.5 inches consisting of about 200 hair strands (equivalent to a #2 pencil in size) from the scalp provides 100mg of hair, ideal for both screening and confirmation tests. For comprehensive tests exceeding 10 panels, and for EtG add-ons, a specimen of 150mg is advised. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable amount of body hair can be utilized. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

There are four essential steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially processing a sample into a laboratory's database. This process includes confirming the sample's seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and entering any other data absent from an electronic chain of custody system.

Screening provides an early rapid check for drug misuse. While cost-effective for ruling out drug use on most samples, a positive screening requires confirmation to be valid for legal use. Any sample that tests presumptively positive in Screening will need secondary confirmation.

If the Screening stage returns a presumptive positive, additional hair from the original sample is extracted for the Extraction stage. Here, drugs are leached from the hair at lower concentrations compared to using other testing methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging technique.

Confirmation of any positive screening result uses GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation as necessary. The full laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can track drug consumption for up to 90 days, unlike urine tests which cover a shorter timeframe.
• Testing is hard to evade: Cheating a hair drug test is very complicated, enhancing result reliability.
• Historical data provision: It reveals a pattern of drug use over time, not just recent usage.

Limitations:

• Recent usage detection: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug testing is typically pricier than other testing methods.
• Result inconsistencies: Diverse factors like hair color and hair growth variations can influence drug metabolite levels in hair.

Note: The term "hair follicle tests" is commonly used, but the test itself evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When assessing drug use in East Galesburg, IL, hair follicle tests hold a decided edge over traditional urine tests. Not only do they offer higher detection accuracy, but their reliability reduces false negatives.

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.
