Hair Follicle Drug Testing - Hazel Green, KY

What it is, How it works

Hair analysis is increasingly recognized as a powerful method for identifying drug and alcohol consumption. By capturing biomarkers in the strands of hair as they grow, it offers a comprehensive history of substance use. When collected close to the scalp, hair can provide a detection window for drugs and alcohol of up to roughly three months. It's simple to collect, challenging to tamper with, and easy to transport.

To obtain an ideal sample for screening and confirmation, a 1.5-inch segment consisting of around 200 hair strands, comparable to the thickness of a #2 pencil, is necessary to yield 100mg of hair. For tests like EtG, add-ons, or any beyond 10 panels, it is advisable to gather 150mg of hair. It’s recommended to use a jeweler's scale for weighing the sample. If scalp hair isn't available, an equivalent amount of body hair may be collected. The term head hair refers exclusively to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step, where a sample is processed into a lab’s system. This involves ensuring the sample was sealed and shipped correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry needed that isn't covered by an electronic chain of custody system.

Screening is the next step, providing an initial evaluation for the presence of drugs. While Screening is a cost-efficient technique to dismiss drug use in most samples, confirmation is required for a positive screen to be valid in legal proceedings. Any samples that are preliminarily positive in Screening require a subsequent confirmation.

If a sample shows a presumptive positive result in the Screening phase, more hair will be taken from the original sample and prepared for Extraction. During Extraction, drugs are extracted from hair at a lower concentration compared to other methods like urine or oral fluid, making hair drug screening one of the most complex methodologies to execute.

Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect drug use for up to 90 days, unlike urine tests which have a shorter detection duration.
• Resistance to cheating: Hair drug tests are hard to tamper with, ensuring more reliable results.
• Historical usage insight: Provides a timeline of drug usage over a long span, instead of only recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than other drug testing approaches.
• Result variations: Factors like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Even though often called "hair follicle tests", the test processes the hair strand and not the hair follicle located 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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
