Hair Follicle Drug Testing - Cajahs Mountain, NC

What it is, How it works

The utilization of hair testing has emerged as a robust method for detecting drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by ensnaring biomarkers within the strands as they grow. When collected near the scalp, hair can offer a detection period of up to roughly 3 months for various substances. Hair collection is straightforward, relatively tamper-resistant and easily shippable.

A 1.5-inch sample consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, 150mg of the sample is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair might be collected. Head hair specifically refers to scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

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

Accessioning involves incorporating a sample into the laboratory’s system. The process includes confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody system.

Screening entails an initial rapid assessment for signs of substance abuse. Though Screening offers an economical approach to exclude drug usage in most cases, a positive screen requires confirmation to be legally admissible. Any sample presumptively positive in Screening requires further confirmation.

When a sample tests presumptively positive during Screening, more hair is extracted from the initial sample and prepared for Extraction. In this phase, substances are separated from hair at markedly lower concentrations than in other methodologies (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology to execute.

Using GC/MS, GC/MS/MS or LC/MS/MS, positive screening results undergo Confirmation. All presumptive positive samples are cleansed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption up to 90 days prior, unlike urine tests that have a relatively limited detection period.
• High resistance to tampering: Cheating a hair drug test is exceedingly challenging, which enhances result accuracy.
• Offers historical insights: It can reveal drug usage patterns over time rather than just recent use.

Limitations:

• Inability to identify recent consumption: Drugs typically become detectable in hair approximately 5-7 days post-use.
• Higher cost: Hair drug tests tend to be pricier compared to alternative drug testing techniques.
• Result variations: Elements such as hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed "hair follicle tests", the analysis involves the hair strand itself 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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
