Hair Follicle Drug Testing - Cuzco, IN

What it is, How it works

Hair testing has emerged as a potent means for identifying drug and alcohol consumption. The hair captures biomarkers within its fibers, creating a prolonged history of substance use as it grows. By collecting hair near the scalp, it yields around a three-month detection window for substances. Hair is easily obtained, relatively tamper-resistant, and straightforward to transport.

A segment of hair that's 1.5 inches and comprises roughly 200 strands (about the width of a #2 pencil) near the scalp provides 100mg of hair, which is ideal for preliminary and confirmatory testing. For EtG, supplementary assays, and tests surpassing 10 panels, a 150mg sample is advised. Using a jeweler’s scale to measure the sample's weight is recommended. If scalp hair is absent, the equivalent amount of body hair may be utilized. References to head hair pertain solely to scalp hair, while body hair includes all other types (like facial or underarm hair).

Process Overview

The key procedures in processing drug tests in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning addresses the initial phase of incorporating a sample into a lab's framework. This involves ensuring the sample is adequately sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any other data input not managed by an electronic chain of custody system.

Screening is a preliminary test to detect drugs of abuse. Although it's a cost-efficient tactic to exclude drug use for most specimens, positive findings must be confirmed for court admissibility. Presumptively positive samples during Screening require secondary verification.

Should a sample be presumptive positive at the Screening phase, additional hair is extracted from the original sample for the Extraction step. Here, drugs are retrieved from hair at significantly reduced concentrations than in alternatives (such as urine or saliva), which makes hair drug testing one of the more challenging methodologies to execute.

Confirmation of positive screenings occurs through GC/MS, GC/MS/MS, or LC/MS/MS processes, with all presumptive positive specimens being cleansed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized according to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify substance use extending to 90 days, unlike urine tests, which have shorter windows.
• Challenging to bypass: The stringent nature of hair drug testing increases result accuracy.
• Depicts historical patterns: It reveals drug use trends over time, not merely recent activities.

Limitations:

• Inability to detect immediate use: Drugs take about 5-7 days before becoming traceable in hair.
• Expense: Hair drug tests are often costlier compared to other methods.
• Result variations: Hair color and personal growth rates can influence drug metabolite levels in the hair.

Note: While commonly labeled as "hair follicle tests", the assessment actually evaluates the hair strand and not the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing

The advantage of hair follicle testing over traditional urine tests is clear in Cuzco, IN. Hair testing provides superior detection accuracy and reliability.

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.
