Hair Follicle Drug Testing - Roff, OK

What it is, How it works

Recognized as a potent technique, hair testing is utilized for identifying the usage of alcohol and drugs. Hair captures a long-term trace of alcohol and other substances by embedding biomarkers within the fibers of the growing hair strand. When sampled near to the scalp, hair can offer a detection window of up to around three months for alcohol and drugs. It's easy to gather, somewhat challenging to tamper with, and simple to ship.

A 1.5-inch segment of approximately 200 hair strands (resembling the size of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or panels beyond 10, a 150mg specimen is advisable. It is suggested to weigh the sample on a jewelry scale. If scalp hair isn't accessible, a similar amount of body hair is acceptable. Head hair specifies only scalp hair, while body hair covers all other hair types (like facial, axillary, etc.).

Process Overview

The key stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the preliminary processing of a sample into a laboratory system. It includes verifying that the sample was correctly sealed and dispatched, providing it with an arbitrary LAN (Laboratory Accessioning Number), and completing any additional data input not supplied by an electronic chain of custody system.

Screening consists of a swift initial check for abuse drugs. While being cost-effective for negating drug use on most samples, a positive screening result needs confirmation for admissibility in legal proceedings. Samples showing presumptive positives during Screening require a follow-up confirmation.

In the event of a presumptive positive at the Screening phase, extra hair is extracted from the initial sample and prepped for Extraction. This stage involves extracting drugs from hair at much lower concentrations than other methodologies (like urine or oral fluid), thus making hair drug tests the most challenging methodology to perform.

The Confirmation process for any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleansed prior to confirmation if necessary. The laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair specification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests identify drug usage for up to 90 days, contrasting with urine tests that have a shorter span.
• Challenging to falsify: It's extremely tough to manipulate a hair drug test, thus increasing result accuracy.
• Offers historical data: Presents a drug use pattern over time, not just recent consumption.

Limitations:

• Incapable of detecting recent usage: It takes about 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are typically costlier than other screening methods.
• Result variance: Factors like hair hue and individual growth variations can influence the concentration of drug metabolites in the hair.

Note: Despite being frequently termed as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
