Hair Follicle Drug Testing - Funkley, MN

What it is, How it works

Hair assessment has emerged as a robust technique for detecting substance and alcohol consumption. Hair captures a historical account of alcohol and other substances by encapsulating biomarkers within the fibers of the growing hair shaft. When collected near the scalp, hair can offer a detection span of up to around 3 months for alcohol and other drugs. Hair is straightforward to collect, fairly challenging to tamper with, and simple to transport.

A 1.5-inch segment comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample for screening and confirmation. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be gathered. In regard to head hair, we specifically refer to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four primary steps involved in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab’s system. This encompasses confirming that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry not provided by an electronic chain of custody system.

Screening involves an initial rapid assessment for substances of abuse. While Screening is an economical approach to rule out substance usage in most samples, a positive screen must be substantiated to be valid in legal settings. Any samples that are presumptively positive in Screening necessitate a secondary confirmation.

If a sample is presumptively positive in the Screening stage, more hair is extracted from the initial sample and prepped for Extraction. During this stage, drugs are removed from hair at a considerably lower concentration than in other methodologies (e.g., urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficult to tamper: Cheating a hair drug test is quite challenging, enhancing the accuracy of results.
• Offers historical information: It can illustrate a pattern of substance use over time, not merely recent consumption.

Limitations:

• Incapable of detecting recent use: It requires about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variations: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed as "hair follicle tests", the test itself examines the hair shaft and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle versus urine testing in Funkley, MN, the benefits of hair testing become apparent. Hair tests offer superior detection accuracy, capturing drug use over a longer period.

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.
