Hair Follicle Drug Testing - Gloucester Courthouse, VA

What it is, How it works

Hair testing is regarded as a potent instrument for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of the emerging hair strand, hair offers a prolonged history of alcohol and other substances. When obtained near the scalp, hair can furnish up to about a 3-month detection interval for alcohol and drugs. Hair is easy to collect, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (analogous to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for testing and validation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the specimen on a jeweler’s scale. If no scalp hair is available, a comparable volume of body hair can be gathered. With respect to head hair, we specifically mean scalp hair. Body hair comprises all other hair types (facial, axillary, etc.).

Process Overview

The key steps implicated in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the first processing phase of a sample into a laboratory’s framework. This step includes ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not available in an electronic chain of custody system.

Screening entails an initial rapid examination for drugs of abuse. Although Screening is a cost-efficient means to eliminate drug usage for the majority of samples, a positive screen mandates verification to be valid in legal proceedings. Samples that are presumptively positive during Screening require a following confirmation.

If a sample is potentially positive during the Screening process, additional hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are extracted from hair at considerably lower concentrations than other processes (e.g., urine or oral fluid), hence why hair drug screening is the most complex methodology to execute.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as needed. The full laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug tests can identify drug use for up to 90 days, while urine tests have a more limited detection period.
• Hard to manipulate: It is notably challenging to deceive a hair drug test, thus enhancing accuracy of the results.
• Yields historical information: It can demonstrate a trend of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent intake: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair drug tests are usually pricier compared to other drug testing techniques.
• Result variations: Aspects such as hair color and individual differences in hair growth can influence the levels of drug metabolites in the hair.

Note: Commonly known as "hair follicle tests", the test itself examines 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.
