Hair Follicle Drug Testing - Isle La Motte, VT

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair encases biomarkers within the strands as it grows, providing a prolonged record of alcohol and drug use. When hair is obtained close to the scalp, it can reveal alcohol and drug usage for roughly a 3-month duration. Hair collection is straightforward, hard to compromise, and simple to transport.

Obtaining a 1.5-inch segment of roughly 200 hairs (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg of hair is advised. It's suggested to use a jeweler's scale for weighing the specimen. If scalp hair cannot be collected, a similar quantity of body hair may be used. Reference to head hair implies scalp hair exclusively, whereas body hair includes all other types (such as facial, and axillary).

Process Overview

Laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is integrated into the lab's system. This step ensures the sample was correctly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes any extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary fast test to check for drug abuse. Although Screening is cost-efficient for eliminating drug use in most samples, a positive result must be verified for court acceptance. Samples that are tentatively positive in Screening require another confirmation.

If Screening suggests a positive result, additional hair is taken from the original sample for Extraction. At this stage, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), marking hair drug screening as one of the most complex methodologies to carry out.

Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any tentatively positive samples undergo washing before confirmation as necessary. The end-to-end lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation in line with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug usage for up to 90 days, whereas urine tests offer a shorter detection period.
• Hard to manipulate: Manipulating a hair drug test is extremely challenging, ensuring more precise results.
• Offers historical insight: This method can trace a history of drug use over time, not just recent use.

Limitations:

• Incapable of identifying recent use: Drugs take about 5-7 days to become noticeable in hair.
• Expense: Hair drug tests generally cost more than other drug testing approaches.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite commonly being called "hair follicle tests," the test evaluates the hair strand itself, 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.
