Hair Follicle Drug Testing - Eugene, OR

What it is, How it works

Hair testing is now regarded as a significant means for identifying drug and alcohol consumption. By embedding biomarkers within its fibers, hair retains a long-term record of alcohol and drug usage. When gathered near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. Hair is straightforward to gather, tough to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hairs (about the diameter of a #2 pencil) closest to the scalp results in 100mg of hair, which is the preferred sample size for screening and confirmation. For EtG, additional tests, and/or over 10-panel screens, a 150mg sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, an equivalent portion of body hair may be used. References to head hair pertain solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four fundamental steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step involving the process of inputting a sample into the laboratory’s system. This step ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry not captured by an electronic chain of custody system.

Screening involves a preliminary rapid test for drugs of abuse. While Screening serves as a cost-efficient method to dismiss drug usage in most samples, a positive Screening necessitates confirmation for legal admissibility. Samples that are possibly positive in Screening require a secondary Confirmation process.

In the case of a preliminary positive result from Screening, additional hair is extracted from the original sample for the Extraction phase. During this stage, drugs are separated from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to perform.

Confirmation for any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleaned prior to Confirmation as necessary. The full lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use up to 90 days, unlike urine tests that have a shorter detection period.
• Hard to deceive: Tampering with a hair drug test is quite difficult, which enhances the result's accuracy.
• Historical insights: They can illustrate a pattern of drug use over a duration, beyond just recent use.

Limitations:

• Incapable of detecting recent use: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more compared to other drug testing techniques.
• Variable results: Factors like hair color and personal hair growth differences can influence drug metabolite levels in the hair.

Note: Though often called "hair follicle tests", the analysis actually focuses on the hair strand and not the follicle beneath 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.
