Hair Follicle Drug Testing - Crescent City, IL

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Through embedding biomarkers in the strands of hair as they grow, hair offers a prolonged record of alcohol and drug presence. When the sample is collected near the scalp, it allows for an estimated 3-month window of detection for substance use. The process of collecting hair is straightforward, resistant to tampering, and convenient for shipping.

A sample comprising 1.5 inches of approximately 200 hair strands (roughly equivalent to the girth of a #2 pencil) near the scalp will yield 100mg of hair, which is considered optimal for screening and confirmation. When testing for EtG, additional panels, or when exceeding 10 panels, 150mg of the specimen is advisable. It is suggested that the sample be measured using a jeweler's scale. If scalp hair cannot be used, an equal quantity of body hair can be collected instead. When addressing head hair, we mean scalp hair specifically, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The primary phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into the lab’s framework. This phase verifies that the sample is properly sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not completed by an electronic custody chain system.

Screening serves as an initial examination for substances of abuse. While cost-effective, Screening is mainly used to eliminate drug use in most samples; a positive result here requires confirmation for legal validity. Any specimens that potentially test positive during Screening necessitate subsequent confirmation.

Should a sample yield a presumptively positive result during Screening, additional hair will be extracted from the original specimen for preparation for the Extraction phase. Here, drugs are drawn from hair at a significantly lower concentration compared to other methods such as urine or oral fluid testing, thereby making hair testing a challenging protocol to develop.

GC/MS, GC/MS/MS, or LC/MS/MS methodologies are employed to confirm any positive Screening results. Before confirmation, all samples that are initially positive undergo washing as needed. The complete laboratory workflow, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation as well as ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a shorter detection timeframe.
• Difficulty to cheat: Manipulating a hair drug test is extremely hard, ensuring more precise outcomes.
• Provides historical data: It offers a timeline of drug use patterns over an extended duration, not only current use.

Limitations:

• Cannot detect recent use: Drugs take around 5-7 days to become traceable in hair.
• Cost: Hair drug testing is frequently more costly compared to other drug testing techniques.
• Variations in results: Elements like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair strands.

Note: Although commonly referred to as "hair follicle tests", the assessment actually evaluates the hair strand, not the follicle located below 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
