Hair Follicle Drug Testing - Teeds Grove, IA

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands of the growing hair, offering a prolonged record of alcohol and other drugs. When taken near the scalp, hair can reveal drug and alcohol use for up to about three months. Collecting hair is straightforward, with minimal chance for tampering, and it can be easily transported.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) taken closest to the scalp, yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is absent, a similar amount of body hair can be collected. When we refer to head hair, it pertains solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a sample into a laboratory’s system. This step ensures the sample’s seal and shipment were handled correctly, allocates a random LAN (Laboratory Accessioning Number), and completes any further data entry that is absent from an electronic chain of custody system.

Screening offers a preliminary, swift assessment for drugs of abuse. Even though Screening is economically efficient for negating drug usage in most samples, confirmed results are essential for court admissibility. Any Screening results that indicate presumptive positivity necessitate further Confirmation.

For samples showing presumptive positivity in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In Extraction, drugs are isolated from hair at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute effectively.

Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed appropriately. The thorough laboratory operation—from Accessioning through Confirmation—is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, as opposed to urine tests which cover a shorter detection span.
• Hard to falsify: Falsifying results in a hair drug test is highly challenging, ensuring greater accuracy.
• Offers historical insight: It reveals a drug use pattern over an extended timeframe, rather than merely recent consumption.

Limitations:

• Unable to detect recent usage: Detection of drugs in hair takes roughly 5-7 days.
• Price: Hair drug tests generally cost more than other drug testing procedures.
• Result variability: Individual differences in hair growth and hair color can influence drug metabolite concentration within hair.

Note: Often termed "hair follicle tests", these tests actually analyze the hair strand, not the follicle beneath 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.
