Hair Follicle Drug Testing - Le Roy, MN

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair strands provide an extended history of substance use by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can offer a detection span for substances up to about three months. It's easy to gather, tough to tamper with, and convenient to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) from close to the scalp amounts to 100mg, the ideal quantity for both screening and confirming. For EtG assessments, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. It's best to weigh the sample using a jeweler's scale. If scalp hair isn't accessible, an equivalent amount of body hair is an alternative. When discussing head hair, it specifically means scalp hair. Body hair encompasses all other types (like facial and axillary hair).

Process Overview

There are four essential phases in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the sample's incorporation into the lab's system. This process verifies that the sample is properly sealed and transported, allocates a unique LAN (Laboratory Accessioning Number), and completes any supporting data entry absent in an electronic chain of custody protocol.

Screening acts as an initial rapid assessment for drug abuse. Although Screening serves as an economical means of dismissing drug use in most cases, a positive outcome necessitates confirmation for legal admissibility. Any samples indicated as potentially positive during Screening require secondary confirmation.

If a test shows a potential positive at the Screening stage, additional hair from the original sample is used and prepped for Extraction. In this step, drugs are drawn out from hair in lower concentrations compared to other methods (such as urine or oral fluid), which contributes to the complexity of hair drug screening.

Confirmation of any positive result from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a potential positive indication undergo washing prior to confirmation as necessary. The entire laboratory workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and accreditation according to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests, hair tests provide up to 90 days of detection time for drug use.
• Challenging to deceive: A hair drug test is difficult to manipulate, enhancing the accuracy of its results.
• Historical insight: This test offers a usage pattern over time rather than just recent activity.

Limitations:

• Inability to track recent usage: Drugs require around 5-7 days to become noticeable in hair strands.
• Expense: Compared to other drug testing types, hair tests usually have higher costs.
• Result variability: Aspects like hair color and individual hair growth differences can influence the drug metabolite levels in hair.

Note: Widely called "hair follicle tests", this testing method examines the hair itself, 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.
