Hair Follicle Drug Testing - Rainier, OR

What it is, How it works

Hair analysis is now recognized as an effective method for detecting substance use, providing a detailed history through biomarkers trapped in hair fibers. Collected near the scalp, hair can indicate alcohol and drug use over a period of up to 3 months. It is easy to acquire, hard to alter, and straightforward to transport.

A 1.5-inch cut of roughly 200 hair strands (approximately #2 pencil thickness) from the scalp yields 100mg, an ideal quantity for tests. For EtG, add-ons, and/or tests beyond 10 panels, 150mg is preferred. Using a jeweler’s scale is suggested for accuracy. If scalp hair isn’t accessible, a similar amount from body hair can be used. Head hair pertains only to scalp hair, while body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates sample processing into the lab’s system. This involves checking sample sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and entering any data not already in an electronic chain of custody.

Screening is an initial quick test for drugs of abuse. While economical for ruling out usage in most samples, a positive screen requires confirmation for court admissibility. All samples presumptively positive in screening must be confirmed.

If presumption is positive during Screening, additional hair is gathered for Extraction. Here, drugs are extracted from hair at low concentrations, making hair drug screening a complex process.

Confirmation of positive screens is done using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are washed prior to confirmation as needed. The full lab process from Accessioning to Confirmation is under the purview of CAP (College of American Pathologists) and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Prolonged detection: Hair tests can reveal drug use for up to 90 days, unlike the shorter span of urine tests.
• Hard to manipulate: Hair drug tests are very difficult to falsify, ensuring more precise results.
• Historical insight: It demonstrates a drug use pattern over time, beyond mere recent use.

Limitations:

• Cannot trace recent usage: Detection in hair requires 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variation: Factors like hair color and personal hair growth rates can affect drug metabolite concentration in the hair.

Note: The test usually termed "hair follicle tests" actually examines the hair strand, not the follicle under the scalp.

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
