Hair Follicle Drug Testing - Castle Danger, MN

What it is, How it works

The utilization of hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair acts as a repository of drug and alcohol biomarkers within the fibers of the hair as it grows. When gathered near the scalp, the hair can reveal a substance use history spanning up to around three months. This method is straightforward to gather, somewhat resistant to tampering, and convenient to transport.

A hair sample measuring 1.5 inches, comprising approximately 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp, results in about 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG detection, additional tests, or screenings over 10-panel tests, it's advisable to utilize 150mg of the hair sample. We suggest measuring the sample with a jeweler's scale. In cases where scalp hair is not available, a similar amount of body hair can be used. When referring to head hair, it specifically means scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary stages in processing a lab drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample’s initial intake into the lab system. This step confirms that the sample has been properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent in an electronic chain of custody system.

Screening entails an initial swift assessment for drug presence. Although Screening is an economical method to rule out drug use for most samples, a positive result must be verified to be legally valid. Samples flagged as presumptively positive during Screening necessitate further confirmation.

When a sample is deemed presumptively positive during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to other methods (such as urine or oral fluid), underscoring the challenge of hair drug screenings.

Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as needed. The comprehensive lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can identify drug use up to 90 days, unlike urine tests which have more limited detection periods.
• Hard to manipulate: Cheating a hair drug test is notably challenging, enhancing accuracy.
• Chronological data: It reveals a pattern of drug use over time, not merely recent consumption.

Limitations:

• Incapable of identifying recent use: Drugs need approximately 5-7 days post-use to become detectable in hair.
• Expense: Hair drug testing is typically costlier than other testing approaches.
• Result variability: Factors like hair pigmentation and individual growth rates can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis concerns the hair shaft rather than 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.
