Hair Follicle Drug Testing - Rochester, IN

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug usage by trapping biomarkers in the hair’s fibrous structure as it grows. When collected near the scalp, hair can offer a detection timeline of up to three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch hair sample consisting of about 200 strands (approximately the width of a #2 pencil) nearest to the scalp provides 100mg of hair, the ideal sample for both screening and confirmation purposes. For EtG, additional tests, and/or panels exceeding 10, 150mg of specimen is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be used. When referencing head hair, we refer exclusively to scalp hair. Body hair includes all other types (facial, armpit, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into the laboratory’s system. This step verifies that the sample was appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of abuse. While Screening is an economical method to eliminate drug use in most samples, a positive result requires Confirmation to be valid in court. Samples with a presumptive positive in Screening necessitate a secondary confirmation.

If Screening results are presumptively positive, additional hair is taken from the initial sample and prepped for Extraction. This stage involves extracting drugs from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging technique to perform.

Confirmation of any positive Screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The end-to-end laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, as opposed to urine tests, which have a shorter window.
• Difficulty to cheat: Cheating a hair drug test is exceedingly difficult, ensuring more reliable results.
• Provides historical data: It provides a timeline of drug use over time, not just recent use.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are generally more costly than other testing methods.
• Variations in results: Factors such as hair color and individual hair growth rates may influence the concentration of drug metabolites in hair.

Note: Although commonly referred to as "hair follicle tests", the test itself examines the hair strand, 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.

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.
