Hair Follicle Drug Testing - Ranier, MN

What it is, How it works

Hair analysis has emerged as a formidable method for uncovering drug and alcohol consumption. Hair chronicles a prolonged history of substance use by encapsulating biomarkers within the fiber of the developing hair strand. When procured near the scalp, hair can illuminate up to roughly a 3-month timeframe for detecting alcohol and drugs. Hair's acquisition is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's diameter) nearest the scalp will produce 100mg of hair, the optimal sample for evaluation and verification. For EtG, add-ons, and tests exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to measure the sample. In cases of absent scalp hair, a corresponding amount of body hair is permissible. Head hair pertains solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The quartet of fundamental steps in the lab's handling of a drug test result includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into the lab system. This step involves confirming the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any outstanding data input not provided by an electronic chain of custody system.

Screening constitutes an initial swift assessment for substance abuse. Although Screening is a cost-efficient means to exclude drug usage in most samples, a positive result demands confirmation for legal admissibility. Samples that indicate a presumptive positive in Screening necessitate a secondary corroboration.

When a sample is presumptively positive in the Screening phase, additional hair is drawn from the initial sample and readied for Extraction. During Extraction, drugs are isolated from hair at substantially lower concentrations compared to other methods (e.g., urine or saliva), rendering hair drug screening the most challenging technique to execute.

Confirmation of any screening positive is executed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleaned prior to confirmation as required. The entire lab workflow from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and is accredited in compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can discover drug use for as long as 90 days, unlike urine tests that have a briefer detection span.
• Difficulty to cheat: Hair drug tests are challenging to deceive, resulting in more reliable outcomes.
• Provides historical data: Demonstrates a pattern of drug use over time, not merely recent activity.

Limitations:

• Cannot detect recent use: It generally requires 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests typically cost more than other testing techniques.
• Variations in results: Elements, like hair color and individual growth differences, can impact drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the examination scrutinizes the hair strand 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.
