Hair Follicle Drug Testing - Barronett, WI

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair captures biomarkers within the fibers of the growing strand, offering a long-term record of substance use. When cut near the scalp, hair can reveal a detection timeframe of up to roughly 3 months for drugs and alcohol. It is straightforward to gather, relatively challenging to tamper with, and simple to transport.

A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp will provide 100mg, which is the ideal quantity for analysis and verification. For EtG, additional tests, or screening beyond 10 panels, a sample of 150mg is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair can be utilized. When we mention head hair, it refers solely to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The key procedures in assessing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about the initial incorporation of a sample into a lab’s database. This phase involves checking that the sample has been securely sealed and sent, assigning a LAN (Laboratory Accessioning Number) randomly, and entering any additional data not captured by an electronic chain of custody system.

Screening performs an initial drug presence check. Although it’s a cost-effective approach to exclude drug use in most samples, a positive finding must be verified to be valid for legal purposes. Any samples that test positive during Screening require further confirmation.

In cases where a sample tests positive in Screening, additional hair from the initial collection is readied for Extraction. This stage extracts drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which is why hair drug screening is particularly challenging.

Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples are washed as required. Every step from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and meets ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can uncover drug use for up to 90 days, unlike urine tests with shorter windows.
• Hard to manipulate: Cheating a hair drug test is highly difficult, ensuring more precise outcomes.
• Captures historical usage: Offers insights into patterns of drug use over time, not just recent activity.

Limitations:

• Limited immediate detection: Drugs take roughly 5-7 days to show in hair.
• Price: Hair tests tend to be costlier than other testing techniques.
• Result variability: Hair attributes such as color and personal growth differences can influence drug metabolite levels in hair.

Note: Commonly referred to as "hair follicle tests", the examination analyzes the hair strand, not the follicle within 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. 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.
