Hair Follicle Drug Testing - Marble City Community, OK

What it is, How it works

Hair testing is now perceived as a robust method for identifying drug and alcohol consumption. It offers a comprehensive timeline of alcohol and drug use by encapsulating biomarkers within the fibers of the hair as it grows. Collected near the scalp, hair can reveal drug and alcohol use within an approximate 3-month timeframe. This method is straightforward to collect, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment, comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, extra tests, and/or those exceeding 10 panels, a 150mg specimen is advised. It's beneficial to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, a comparable amount of body hair can be used. When referencing head hair, it signifies scalp hair solely. Body hair denotes all other variations (facial, axillary, etc.).

Process Overview

The drug test result process in the laboratory is comprised of four chief stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial introduction of a sample into the laboratory's system. This covers verifying the sample's secure sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody documentation.

Screening is a preliminary swift evaluation for drugs of abuse. While Screening is an economical arrangement to dismiss drug consumption on most samples, a positive result necessitates confirmation for it to be recognized in court. Samples that return a presumptive positive in Screening demand further confirmation.

Should a sample be presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. During Extraction, drugs are drawn from hair at concentrations much lower than other methods (e.g., urine or oral fluid), highlighting why hair drug screening is among the most intricate methodologies.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive are cleansed before confirmation as needed. Each step of the laboratory process, from Accessioning to Confirmation, undergoes scrutiny in compliance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests detect drug use for up to 90 days, unlike the shorter detection window of urine tests.
• Hard to manipulate: Hair drug tests are highly resistant to tampering, ensuring result precision.
• Shows usage patterns: They offer an insight into drug usage trends over time, not merely immediate use.

Limitations:

• Cannot reveal immediate use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests usually incur greater costs than other testing methods.
• Result variability: Elements like hair pigmentation and personal growth rates can influence drug metabolite concentrations in the hair.

Note: Commonly known as "hair follicle tests", the assessment 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.
