Hair Follicle Drug Testing - Williamsburg, OH

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands, offering a comprehensive history of alcohol and substance usage over time. When cut close to the scalp, hair can reveal drug and alcohol use over a period of up to 90 days. Hair samples are easy to obtain, challenging to tamper with, and simple to transport.

A 1.5-inch hair sample, consisting of roughly 200 strands (comparable to the thickness of a #2 pencil), equates to 100mg of hair—the optimal quantity for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is urged. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair can be collected. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other types such as facial and axillary hair.

Process Overview

The laboratory processing of drug test results comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves incorporating a sample into the laboratory system initially. This step includes verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry absent from an electronic chain of custody system.

Screening is a preliminary and efficient method for detecting drug abuse. Although it is a cost-effective strategy for discounting drug use in most cases, a positive screening must be confirmed for legal admissibility. Any presumptively positive samples from Screening require further confirmation.

Should a sample show a presumptive positive in Screening, a portion from the initial sample is prepared for Extraction. This phase extracts drugs from hair in much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is among the most intricate methods to execute.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation, as needed. From Accessioning to Confirmation, the complete laboratory process is evaluated under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use up to 90 days, unlike urine tests with shorter detection periods.
• Challenging to evade: Hair drug tests are difficult to cheat, resulting in more reliable outcomes.
• Traces historical patterns: They uncover patterns of drug use over time, rather than recent consumption alone.

Limitations:

• Incapable of detecting recent use: Hair takes around 5-7 days to reflect drug presence.
• Expense: Hair drug tests are generally pricier compared to other detection methods.
• Result variability: Factors like hair color and individual growth rates can influence metabolite concentration in hair.

Note: Despite often being termed "hair follicle tests", the analysis evaluates the hair strand rather than 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.

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