Hair Follicle Drug Testing - Elsmere, DE

What it is, How it works

Hair testing is now recognized as a potent method for identifying drug and alcohol consumption. Hair serves as an extended timeline for alcohol and other drug use by embedding biomarkers within the fibers of the developing hair strand. When harvested near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and other drugs. Collection of hair is straightforward, relatively challenging to tamper with, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (similar to the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional assessments, and/or evaluations exceeding 10 panels, a 150mg specimen is advised. It is suggested to use a jeweler’s scale for weighing the specimen. If scalp hair is inaccessible, an equivalent volume of body hair can be gathered. References to head hair pertain exclusively to scalp hair. All other hair types (facial, axillary, etc.) fall under the term 'body hair'.

Process Overview

The laboratory workflow of processing a drug test sample entails four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary entry of a sample into a lab's procedures. This phase consists of validating the proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and inputting any supplementary information absent from the electronic chain of custody system.

Screening comprises an initial swift evaluation for drugs of abuse. Although Screening provides a cost-efficient approach to exclude drug usage in most samples, any positive finding must be validated for court acceptability. Samples deemed presumptively positive in Screening necessitate a secondary confirmation.

Upon a presumptive positive result in the Screening phase, additional hair is extracted from the original specimen for preparation in the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any Screening positive result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug usage for up to 90 days, surpassing the shorter detection period of urine tests.
• Challenging to falsify: Tampering with a hair drug test is quite difficult, ensuring more precise outcomes.
• Compiles historical data: It can outline a pattern of drug usage across time, beyond recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug tests often incur higher costs than alternative drug testing approaches.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the analysis focuses on the hair strand and 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.
