Hair Follicle Drug Testing - Northwest Comanche, OK

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance use. Hair captures a comprehensive history of alcohol and other substances by embedding biomarkers within the fibers of the developing hair shaft. When harvested near the scalp, this can offer a detection period of up to roughly three months for alcohol and other substances. Hair collection is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch portion consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the ideal amount for screening and validation. For EtG, additional tests, and/or panels exceeding ten, it is advised to obtain 150mg of the sample. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unattainable, the same amount of body hair can be used instead. References to head hair pertain only to scalp hair, while body hair denotes all other hair varieties (including facial, axillary, etc.).

Process Overview

The primary stages in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial enrollment of a sample into a lab's process. This incorporates verifying that the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not provided by an electronic custody system.

Screening performs a preliminary assessment for substance abuse. Though Screening is a budget-friendly method to dismiss drug involvement in most samples, a positive screen needs validation for court acceptability. Samples marked presumptively positive during Screening need additional confirmation.

If a sample is marked presumptively positive at the Screening phase, additional hair is extracted from the primary sample and prepped for Extraction. During this phase, substances are retrieved from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluids), which makes hair drug screening a more challenging technique.

Any positive screen result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is washed before they are confirmed if necessary. Each step from Accessioning to Confirmation is undertaken in line with both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can track substance usage for up to 90 days, whereas urine tests provide a shorter span.
• Hard to trick: It is exceedingly hard to deceive a hair drug test, enhancing result precision.
• Offers historical evidence: It showcases drug usage patterns over time, not just recent activity.

Limitations:

• Does not detect recent consumption: It usually takes 5-7 days for substances to be traced in hair.
• Expense: Hair drug examinations typically incur higher costs compared to other testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence the levels of drug metabolites in the hair.

Note: While commonly known as "hair follicle tests", the analysis targets the hair strand and excludes the hair follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Northwest Comanche, OK, the advantages of hair testing outshine traditional urine tests. Hair tests detect drug use over a far extended timeframe, unlike the short window for urine.

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.
