Hair Follicle Drug Testing - Togo, MN

What it is, How it works

Hair analysis is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive record of alcohol and other substance use by capturing biomarkers within the strands as they grow. When gathered near the scalp, a hair sample can provide an approximately 3-month window for detecting alcohol and other substances. Hair samples are straightforward to collect, rather resistant to tampering, and simple to transport.

A sample measuring 1.5 inches consisting of about 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair—ideal for both screening and confirmation. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of the sample is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not an option, an equivalent quantity of body hair may be gathered. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types such as facial and axillary hair.

Process Overview

The procedure for processing a drug test result in the lab includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial process of integrating a sample into a lab’s system. This step includes confirming the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data not covered by an electronic chain of custody system.

Screening entails a preliminary analysis for abuse substances. While Screening is an economical method to exclude drug use for most samples, a screen showing positive must undergo confirmation to be legally valid. Any samples with a presumptive positive in Screening need an additional confirmation step.

Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples showing presumptive positive results receive a wash before confirmation if necessary. The complete lab process from Accessioning through Confirmation undergoes review under the CAP (College of American Pathologists) Hair criteria and meets the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for up to 90 days, unlike urine tests which have a reduced detection period.
• Hard to circumvent: Cheating a hair drug test is extremely challenging, resulting in more reliable outcomes.
• Offers historical insights: It can reveal drug use patterns over time, rather than simply indicating recent use.

Limitations:

• Not able to detect recent use: It typically takes around 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug testing is usually pricier than alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth differences may impact the level of drug metabolites in hair.

Note: Although often labeled as "hair follicle tests", the test assesses the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Togo, MN, hair follicle testing surpasses urine testing due to its superior detection capability. Hair tests detect drug use with greater accuracy and over a longer period, offering employers a more reliable testing solution.

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.
