Hair Follicle Drug Testing - Witt, IL

What it is, How it works

Hair testing is perceived as an effective method for identifying drug and alcohol presence. The fibers of a hair strand in growth capture biomarkers, offering an extended timeline of alcohol and drug history. When taken close to the scalp, hair can reveal usage of alcohol and drugs up to roughly three months back. Hair is straightforward to gather, less prone to tampering, and convenient to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil diameter) from near the scalp provides 100mg, which is ideal for screening and confirmation. For EtG, additional panels, and tests exceeding 10 panels, 150mg is suggested. Utilizing a jeweler's scale for specimen weighing is advised. If scalp hair isn't available, an equal quantity of body hair might be collected. By head hair, we mean solely scalp hair. Conversely, body hair includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial phase whereby a sample enters the laboratory system. It includes verifying the integrity and proper shipment of the sample, generating a LAN (Laboratory Accessioning Number) randomly, and finalizing any outstanding data entry absent from an electronic chain of custody system.

Screening serves as a preliminary examination for drug presence. While Screening is a budget-friendly approach to exclude drug use in most samples, a favorable screen requires a confirmation for court validity. Samples that test presumptive positive in Screening undergo further confirmation.

Presumptive positives in Screening necessitate additional hair extraction from the initial specimen for further Extraction. During this phase, drugs are isolated from the hair at a considerably lower concentration than alternative methods (like urine or oral fluid), illustrating why hair testing is among the most challenging methodologies.

Positive screening results are substantiated through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens are cleaned before confirmation if necessary. The entire laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing identifies drug usage for up to 90 days, surpassing the briefer period of urine tests.
• Resistance to dishonesty: Hair drug tests are notably hard to falsify, enhancing result accuracy.
• Delivers historical context: It offers a usage pattern over extended periods, not solely recent activity.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to become recognizable in hair.
• Expense: Hair drug tests tend to cost more than other testing approaches.
• Potential result variation: Elements such as hair color and unique growth rates can influence drug metabolite levels in hair.

Note: While commonly termed "hair follicle tests", the analysis is conducted on the hair strand itself, 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.
