Hair Follicle Drug Testing - Fort Dodge, IA

What it is, How it works

Hair testing is now widely recognized as an essential method for identifying drug and alcohol consumption. Hair retains a comprehensive timeline of alcohol and drug intake by embedding biomarkers within the strands of growing hair. By collecting hair near the scalp, it can offer a detection timeframe of up to three months for alcohol and drug usage. Hair is easy to gather, relatively resistant to tampering, and straightforward to transport.

A sample of 1.5 inches consisting of around 200 strands of hair (approximately akin to the size of a #2 pencil) sourced closest to the scalp yields 100mg of hair, which is the preferable quantity for evaluation and confirmation. For EtG, supplements, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair might be utilized. When mentioning head hair, it solely pertains to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The four primary phases in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial processing of a sample into a lab’s framework. This task includes confirming that the sample was sealed and conveyed correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry that is not submitted by an electronic chain of custody system.

Screening checks for initial signs of drug abuse. Although Screening is an economical approach to exclude drug usage in the majority of samples, a positive result requires confirmation to be admissible in legal scenarios. Samples with a presumptive positive in Screening necessitate a follow-up confirmation.

For samples yielding presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this stage, drugs are extracted from hair at far lower concentrations compared to other methods (e.g., urine or oral fluid), presenting hair drug screening as the most challenging methodology to execute.

Confirmation for any positive Screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The entire laboratory process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair certification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests are capable of identifying drug use for up to 90 days, whereas urine tests have a shorter timeframe.
• Resistance to deception: Cheating on a hair drug test is extremely difficult, thereby enhancing result accuracy.
• Delivers historical insight: It can establish a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Inability to reveal recent use: It requires approximately 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests typically impose a higher cost compared to other methods of drug testing.
• Result variations: Factors such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Commonly referred to as "hair follicle tests", these tests actually assess the hair strand rather than the hair follicle itself underneath 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.

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.
