Hair Follicle Drug Testing - Darwin, IL

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the strands as they grow. Sampling hair at the scalp can reveal drug and alcohol use within a roughly 90-day detection period. It is straightforward to gather, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (equivalent to a #2 pencil's thickness) near the scalp yields 100mg of hair, ideal for both testing and confirmation purposes. For EtG extensions and tests exceeding ten panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing. If scalp hair is absent, an equivalent amount of body hair is acceptable. 'Head hair' specifically refers to scalp hair. 'Body hair' describes all other types (such as facial, axillary, etc.).

Process Overview

The core stages in lab processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates initial sample processing into a lab's inventory. This step ensures the sample’s proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and handles any extra data entry not covered by an electronic custody chain.

Screening serves as a preliminary evaluation for illegal substances. Though Screening offers a cost-efficient method to assess most samples, any positive findings must be confirmed for courtroom acceptance. Samples testing positive in Screening require a follow-up confirmation step.

Should a sample test positive in Screening, more hair is extracted from the original sample for the Extraction phase. Here, the drugs are isolated from the hair at a significantly reduced concentration than other techniques (e.g., urine or oral fluids), making hair drug testing the most challenging technique to execute.

Confirmation of positive results is achieved using GC/MS, GC/MS/MS or LC/MS/MS. Prior to Confirmation, all presumptive positives undergo washing as necessary. The complete procedure from Accessioning to Confirmation follows both the CAP (College of American Pathologists) guidelines for Hair and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days, as opposed to urine tests with a shorter span.
• Resistance to cheating: Hair drug tests are harder to tamper with, offering increased accuracy.
• Historical usage pattern: It can map drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair drug tests are typically pricier than other testing types.
• Result disparities: Factors such as hair color and individual hair growth rates can influence drug metabolite concentrations.

Note: Though often labeled as "hair follicle tests", the procedure tests the hair strands rather than the follicle itself beneath 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.
