Hair Follicle Drug Testing - Cherry, IL

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol use. Hair captures biomarkers within the strands, providing a long-term record of alcohol and drug usage. When collected near the scalp, hair offers a detection period of up to roughly three months for these substances. Hair is easy to gather, challenging to tamper with, and convenient to transport.

A 1.5-inch section of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample size for screening and confirming results. For tests including EtG, add-ons, or those exceeding 10 panels, 150mg of the specimen is advised. Utilizing a jeweler's scale to weigh the specimen is suggested. If scalp hair is not available, an equivalent amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types, such as facial and axillary hair.

Process Overview

The laboratory processing of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of incorporating a sample into a laboratory's system, involving verification of proper sealing and shipment, assignment of a random LAN (Laboratory Accessioning Number), and completion of any data entry not supplied by an electronic chain of custody system.

Screening serves as an initial rapid assessment for drugs of abuse. While it is economical for excluding drug usage in most samples, a positive screening requires confirmation to be legally valid. Any samples preliminarily positive in Screening necessitate a secondary confirmation.

If a sample tests presumptively positive in the Screening phase, additional hair is taken from the original specimen for Extraction. During this phase, drugs are extracted from hair at concentrations lower than those in other methods (e.g., urine or oral fluid), making hair drug screening a more complex methodology to execute.

Confirmation of any positive results from screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is overseen by both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a more limited detection period.
• Difficulty to cheat: Cheating a hair drug test is very challenging, enhancing result accuracy.
• Provides historical data: The test can reveal a drug use pattern over time, not just recent activity.

Limitations:

• Cannot detect recent use: Drugs take around 5-7 days to be detectable in hair.
• Cost: Hair drug tests are typically more costly than other testing methods.
• Variations in results: Elements such as hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being commonly called "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
