Hair Follicle Drug Testing - Lawndale, MN

What it is, How it works

Hair examinations have become recognized as an influential means for identifying drug and alcohol consumption. The fibers in growing hair strands capture biomarkers, providing a long-term history of substance intake. When hair is collected near the scalp, it can offer up to a 3-month window for detecting drugs and alcohol. Collecting hair is straightforward, difficult to tamper with, and convenient to transport.

A 1.5-inch sample comprised of roughly 200 hair strands (around the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal amount for both screening and verification. For EtG, add-ons, or tests with more than 10 panels, 150mg of the hair sample is advised. Using a jeweler’s scale to weigh the sample is suggested. In cases where scalp hair isn't available, an equivalent quantity of body hair may be gathered. References to head hair pertain solely to scalp hair, whereas body hair refers to all other types (such as facial and axillary hair).

Process Overview

The primary stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins with the initial integration of a sample into the system of a laboratory. This step includes ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data input not covered by an electronic chain of custody system.

Screening involves a preliminary rapid assessment for substances of abuse. While Screening is a budget-friendly method to exclude drug usage in most samples, a positive screening result must be confirmed for court viability. Any samples potentially testing positive in Screening necessitate further confirmation.

For samples appearing positive in the Screening phase, additional hair is extracted from the collected specimen and readied for Extraction. In this process, drugs are recovered from hair at a much lower concentration compared to alternative methods (like urine or saliva), which is why hair drug analyzing is the most challenging method to execute.

Any positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All potentially positive samples undergo washing prior to confirmation if needed. The comprehensive laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can uncover drug intake for up to 90 days, whereas urine tests offer a briefer detection frame.
• Hard to manipulate: Hair drug tests are challenging to deceive, increasing result reliability.
• Delivers historical insight: It shows patterns of drug consumption over a duration, not merely recent use.

Limitations:

• Unable to detect recent intake: It requires about 5-7 days for drugs to show in hair.
• Expense: Hair drug tests tend to be pricier compared to other testing methods.
• Result variability: Elements such as hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly known as "hair follicle tests", this test examines the strand of hair, not the follicle embedded under 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.
