Hair Follicle Drug Testing - Lake City, IA

What it is, How it works

Hair testing is increasingly viewed as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged trace of alcohol and drugs by locking in biomarkers within the hair strand fibers as they grow. If gathered near the scalp, hair can offer around a 90-day window for detecting alcohol and drugs. Hair is straightforward to obtain, rather resistant to tampering, and simple to transport.

Gathering a 1.5-inch segment of about 200 strands of hair (roughly the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is considered the optimal sample for conducting screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest utilizing a jeweler’s scale for measurement. If scalp hair is not available, the equivalent amount of body hair may be used. When mentioning head hair, we mean scalp hair only. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

In processing a drug test outcome, the laboratory follows four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into the lab’s system. This step includes checking that the sample was sealed and delivered correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody system.

Screening serves as a preliminary rapid assessment for drugs of abuse. Whereas Screening is a budget-friendly option to dismiss drug usage in most samples, any screen testing positive needs confirmation to be legally eligible. Samples showing presumptive positives in Screening must undergo further confirmation.

For samples deemed presumptive positives during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are derived from hair at notably lower concentrations than those in alternative methods (e.g., urine or oral fluid), making hair drug screening the most intricate method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive results in the screening process. All presumptive positive samples are often cleansed before confirmation as required. The cycle from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug usage for up to 90 days, while urine tests cover a shorter detection range.
• Challenging to falsify: It is incredibly challenging to manipulate a hair drug test, ensuring result accuracy.
• Provides historical insight: It offers an overview of drug use over a time span, not merely recent intake.

Limitations:

• Incapacity to identify recent use: Approximately 5-7 days are necessary for drugs to surface in hair.
• Expense: Hair drug tests tend to cost more than alternative drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can alter drug metabolite concentrations in the hair.

Note: While often called "hair follicle tests", the analysis involves the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lake City, IA, hair follicle testing stands out over traditional urine tests due to its superior capabilities.

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. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
