Hair Follicle Drug Testing - Duquette, MN

What it is, How it works

Hair analysis has gained recognition as a potent means for identifying drug and alcohol consumption. Hair offers an extensive record of drugs and alcohol use by capturing biomarkers within the fibers of the growing hair strand. When sampled near the scalp, hair can disclose up to roughly a 3-month detection window for alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and easy to transport.

A 1.5-inch section of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional analysis, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair may be gathered. When referencing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the preliminary processing of a sample into a lab's system. This step confirms that the sample was sealed and dispatched correctly, designates a random LAN (Laboratory Accessioning Number), and concludes any outstanding data entry not offered through an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. Although Screening is an economical approach to eliminate drug consumption in most samples, a positive screening requires confirmation to be valid in legal contexts. Any samples that are initially positive in Screening necessitate subsequent confirmation.

Should a sample be initially positive in the Screening stage, additional hair is extracted from the original specimen and prepared for Extraction. During this phase, drugs are isolated from the hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), underscoring why hair drug screening is the most intricate methodology.

Confirmation of any positive screening outcome is pursued via GC/MS, GC/MS/MS, or LC/MS/MS. All samples initially positive are cleaned before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug testing can identify drug usage up to 90 days, unlike urine testing's shorter detection range.
• Resistance to tampering: It’s notably arduous to manipulate a hair drug test, enhancing accuracy.
• Yields historical insight: It can illustrate a timeline of drug use over an interval, not solely recent use.

Limitations:

• Inability to detect recent consumption: Detection in hair typically begins around 5-7 days post-drug use.
• Expense: Hair drug testing is frequently pricier compared to other methods.
• Result variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the examination assesses the hair strand rather than 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.
