Hair Follicle Drug Testing - Greshamville, GA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. The growing hair strand encapsulates biomarkers, offering a long-term record of alcohol and substance use. When taken near the scalp, hair samples can reveal drug and alcohol use over an approximate three-month span. Hair collection is straightforward, hard to tamper with, and convenient to transport.

An ideal test involves a 1.5-inch sample consisting of around 200 hair strands (about the width of a #2 pencil), yielding 100mg—optimal for screening and confirmation. For EtG, additional evaluations, or tests exceeding 10 panels, a 150mg sample is suggested. It's advisable to weigh the sample with a jeweler's scale. If scalp hair isn't an option, a comparable volume of body hair is suitable. References to head hair imply only scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The lab handling of a drug test outcome undergoes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase, integrating a sample into a lab's system. This process involves ensuring the sample is adequately sealed and dispatched, assigning a LAN (Laboratory Accessioning Number), and conducting any outstanding data entry absent from an electronic chain of custody system.

Screening performs an initial rapid assessment for drug misuse. Although Screening is an economical approach to dismiss drug use in most samples, a positive outcome requires verification for legal admissibility. Any samples showing tentative positives in Screening necessitate additional confirmation.

On detection of a tentative positive during Screening, extra hair is sourced from the primary specimen for Extraction. In this phase, drug compounds are isolated from hair at considerably lower concentrations than those found using alternative methods (like urine or oral fluid), posing challenges in hair drug analysis.

Confirming any positive screen result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Each sample with a preliminary positive is cleansed before confirmation, as necessary. The complete lab operation from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the capability to identify drug use up to 90 days, whereas urine tests have a shorter time frame.
• Hard to deceive: The challenge of tampering with a hair drug test enhances result accuracy.
• Historical insights: Hair drug tests reveal a pattern of drug use over a duration, rather than solely recent consumption.

Limitations:

• Inability to identify recent usage: It typically requires 5-7 days for drugs to register in hair analyses.
• Expense: Hair drug testing tends to be costlier relative to other testing methods.
• Variable outcomes: Aspects like hair color and individual variances in growth may influence drug metabolite concentrations in the hair.

Note: Commonly called "hair follicle tests," this procedure examines the hair strand, 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.

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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
