Hair Follicle Drug Testing - Howard, OH

What it is, How it works

Hair analysis is now recognized as a potent method for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers within the fibers of the maturing hair strand. If collected near the scalp, hair can present a detection range extending up to nearly three months for alcohol and various drugs. Hair collection is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch sample comprising approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. Measuring the specimen on a jeweler's scale is recommended. Should scalp hair be absent, an equivalent portion of body hair might be collected. The term head hair refers specifically to scalp hair, while body hair pertains to all other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial processing of a sample into a laboratory’s system. This process verifies that the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug use in most cases, a positive screen requires confirmation for court admissibility. Samples showing presumptive positive results during Screening need additional confirmation.

In cases where a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. Here, drugs are retrieved from hair at lower concentrations compared to other techniques (e.g., urine or oral fluid), emphasizing the intricacy of hair drug testing.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as needed. From Accessioning to Confirmation, the entire lab process is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can monitor drug use for up to 90 days, unlike urine tests which have a shorter detection range.
• Difficulty to tamper with: Cheating a hair drug test is highly challenging, enhancing the accuracy of the results.
• Provides historical insights: Hair testing reveals a drug usage pattern over time, not limited to recent consumption.

Limitations:

• Cannot detect recent use: It takes roughly 5-7 days for drugs to become detectable in hair.
• Cost: Compared to other testing methods, hair drug tests tend to be pricier.
• Variations in results: Factors including hair color and individual hair growth diversity can influence the concentration of drug metabolites in the hair.

Note: Often termed as "hair follicle tests", the examination focuses on the hair strand rather than the hair 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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
