Hair Follicle Drug Testing - Ivanhoe, IL

What it is, How it works

The effectiveness of hair testing in identifying substance intake has been acknowledged. Hair retains a historical record of substance consumption by encapsulating markers within the strands of the growing hair. When hair is sampled near the scalp, it can reveal drug or alcohol use over approximately a three-month duration. Collection is straightforward, tampering is challenging, and transport is convenient.

Acquiring a 1.5-inch portion comprising roughly 200 hair strands (similar to the size of a #2 pencil) closest to the scalp yields 100mg, the optimal quantity for analysis and verification. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to measure the sample is suggested. In the absence of scalp hair, an equivalent weight of body hair may be procured. Head hair exclusively denotes scalp hair. Body hair includes all other types (e.g., facial, axillary).

Process Overview

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

Accessioning marks the beginning of a sample's incorporation into a lab's workflow. This step confirms the sample's intact sealing and proper dispatch, assigns a unique LAN (Laboratory Accessioning Number), and completes any pending data not covered by an electronic chain of custody system.

Screening entails a preliminary assessment for drugs of misuse. While this step is economical for identifying drug absence in most samples, legal validity requires that a positive result undergoes confirmation. Samples with a preliminary positive outcome in Screening necessitate further verification.

In instances where Screening indicates a presumptive positive, an additional amount of hair is extracted from the original sample and readied for Extraction. This stage involves extracting drugs from hair at concentrations lower than those used in other techniques (e.g., urine or oral fluid), rendering hair drug screening the most complex method to execute.

Confirmation for any positive results from screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All specimens marked as presumptively positive undergo cleansing prior to confirmation as deemed necessary. The comprehensive lab process from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation alongside the accreditation for ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect substance use for up to 90 days, contrasting with urine tests which have a more limited detection period.
• Difficulty to cheat: Cheating on a hair drug test is highly challenging, thereby enhancing accuracy.
• Provides historical data: This test outlines a timeline of drug use over a prolonged duration, beyond just recent consumption.

Limitations:

• Cannot detect recent use: A timeframe of about 5-7 days is needed before substances become traceable in hair.
• Cost: Generally, hair drug testing incurs higher costs than other testing methodologies.
• Variations in results: Influences such as hair color and personal differences in hair growth may alter the concentration of drug metabolites in hair.

Note: Commonly termed "hair follicle tests", it examines the strand and not 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.
