Hair Follicle Drug Testing - Remington, IN

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair documents a long-term record of alcohol and drug usage by embedding biomarkers within the structure of the hair as it grows. Hair samples collected near the scalp can reveal a history of up to three months for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.

A sample of 1.5 inches consisting of around 200 hairs (similar to the width of a #2 pencil) from the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, supplementary tests, or analyses exceeding 10 panels, a sample weight of 150mg is advised. The specimen should be measured using a jeweler’s scale. In cases where scalp hair is not accessible, an equivalent volume of body hair is suitable. When discussing head hair, this refers exclusively to scalp hair. Body hair includes all other forms, such as facial or axillary hair.

Process Overview

Laboratory processing of drug tests encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing stage, where a sample is integrated into a laboratory’s workflow. This step involves confirming the secure sealing and shipment of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any missing information beyond what the electronic chain of custody system provides.

Screening serves as a preliminary, rapid inspection for substance abuse. Though cost-effective for excluding drug use in most samples, positive screens require confirmation for legal acceptance. Therefore, any samples that initially test positive in Screening must undergo further validation.

Upon receiving a presumptively positive result from the Screening, additional hair is extracted from the initial sample for further analysis during Extraction. This stage rigorously extracts drugs from hair at considerably lower concentrations compared to other test methods, such as urine or saliva, making hair drug screening particularly challenging.

Confirmation of positive results from screenings is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed when necessary prior to confirmation. The comprehensive laboratory workflow, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and validated against ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over approximately 90 days, while urine tests have shorter detection spans.
• Resilience against manipulation: Hair drug tests are difficult to falsify, ensuring greater result reliability.
• Chronological data: They provide insights into an extended pattern of drug use rather than just recent occurrences.

Limitations:

• Lack of recent use detection: Drugs take about 5-7 days post-consumption to manifest in hair.
• Expense: Hair drug tests often incur higher costs than alternative drug testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair samples.

Note: Commonly called "hair follicle tests", the analysis targets the hair shaft and not the follicle beneath the surface.

Why Hair Follicle Testing Beats Urine Testing

Choosing hair follicle testing over conventional urine tests in Remington, IN, brings clear advantages.

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.
