Hair Follicle Drug Testing - Corbett, OK

What it is, How it works

Hair analysis has become recognized as a potent method for the identification of drug and alcohol consumption. Hair traps biomarkers within the fibers of the developing hair shaft, offering a lengthy timeline for drug and alcohol monitoring. Hair collected near the scalp can provide an estimated 3-month window for detecting drugs and alcohol. Hair is easy to gather, relatively hard to tamper with, and straightforward to transport.

A sample measuring 1.5 inches and consisting of around 200 hair strands (approximately the size of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the preferred quantity for screening and validation. For EtG, additional tests, and/or evaluations exceeding 10 panels, a recommendation for 150mg of the sample is advised. It's suggested to weigh the sample on a jeweler’s scale. If scalp hair is not available, a comparable volume of body hair may be used. When we mention head hair, it specifically denotes scalp hair. Body hair covers all other types of hair (facial, axillary, etc.).

Process Overview

The key stages involved in the laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within a laboratory’s framework. This process checks that the sample was correctly sealed and delivered, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent from an electronic chain of custody protocol.

Screening executes an initial rapid assessment for potential drug abuse. While Screening serves as an economical approach to rule out drug use for most samples, any positive findings need confirmation to be permissible in legal settings. Samples presumed positive during Screening necessitate further confirmation.

Should a sample indicate a presumptive positive result during the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. In this phase, drugs are isolated from hair at a notably lower concentration than in alternative methods (e.g., urine or saliva), explaining why hair drug testing is the most complex methodology to carry out.

Verification of any positive Screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo cleaning prior to confirmation if necessary. The entire laboratory workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for as long as 90 days, in contrast to urine tests with shorter detection timelines.
• Challenging to manipulate: Cheating on a hair drug test is very difficult, enhancing result accuracy.
• Historical data provision: Offers a record of drug usage over time, not just recent consumption.

Limitations:

• Incapable of identifying recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Generally, hair drug tests are pricier than other testing techniques.
• Result variations: Elements like hair color and personal hair growth differences can influence metabolite concentrations in hair.

Note: Although often labeled as "hair follicle tests", the test 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.
