Hair Follicle Drug Testing - Struble, IA

What it is, How it works

Hair testing is recognized as an effective method for identifying the use of drugs and alcohol. The hair captures a prolonged record of these substances by embedding biomarkers within the growing strands. When collected near the scalp, hair facilitates a detection period of up to about three months for alcohol and various drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch sample comprising around 200 hair strands (resembling the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for conducting screening and confirmation. For EtG, add-on tests, and tests exceeding 10 panels, it is advisable to use 150mg of the sample. We recommend using a jeweler's scale for measuring the specimen. In the absence of scalp hair, an equivalent amount of body hair can be collected. When mentioning head hair, we refer exclusively to scalp hair. Body hair pertains to all other hair varieties (facial, axillary, etc.).

Process Overview

The primary procedures in laboratory drug test result processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample within a lab's system. This step entails confirming the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any further data entry lacking from an electronic custody chain system.

Screening comprises an initial swift examination for drug abuse. Though Screening is a cost-efficient method for eliminating drug use in most samples, admittance in court requires verification of a positive screening. Any presumptively positive samples in Screening necessitate secondary confirmation.

If a sample yields a presumptive positive during Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are drawn out from hair at substantially lower concentrations than found with other methods (e.g., urine or oral fluid). Hence, hair drug screening emerges as the toughest methodology to execute.

Confirmation of any positive screening outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to required confirmation. The entire lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests reveal drug usage for up to 90 days, contrasting with urine tests that have a brief detection span.
• Challenging to deceive: Cheating a hair drug test is arduous, ensuring more precise outcomes.
• Supplies historical data: Provides a usage pattern over time, unlike recent-use detection.

Limitations:

• Incapable of spotting recent usage: It takes around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests generally cost more than other testing approaches.
• Result variations: Factors like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the examination assesses the hair strand rather than the follicle 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. 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.
