Hair Follicle Drug Testing - Lawrence Creek, OK

What it is, How it works

Hair analysis has gained recognition as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within its growing strands. When sourced near the scalp, hair can offer an approximate three-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches and consisting of around 200 hair strands (roughly the diameter of a #2 pencil) from near the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, a specimen volume of 150mg is advisable. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair is not accessible, a similar amount of body hair may be used. Reference to head hair signifies scalp hair exclusively. Body hair encompasses all other categories (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results encompasses four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the introductory processing of a sample into a lab’s system. This step involves confirming that the sample was sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any incomplete data entry not covered by an electronic chain of custody system.

Screening entails a preliminary swift assessment for drugs of abuse. While cost-effective for excluding drug use in most samples, a positive screen must be verified to be court-admissible. Any samples testing presumptively positive in Screening require subsequent confirmation.

Should a sample test presumptively positive during Screening, additional hair is taken from the initial specimen for the Extraction process. Here, the drugs are extracted from hair at a notably lower concentration than other methods (e.g., urine or oral fluid), contributing to hair drug screening being the most challenging technique to undertake.

Confirmation of any positive screening outcome is performed with GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples undergo washing before confirmation when necessary. The entire lab series from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair provision and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use up to 90 days, compared to urine tests with a shorter detection frame.
• Challenging to bypass: Cheating a hair drug test is extremely difficult, enhancing result accuracy.
• Reveals historical usage patterns: It offers a timeline of drug use across an extended period rather than just recent usage.

Limitations:

• Inability to detect recent usage: Detecting drugs in hair approximately requires 5-7 days.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Elements like hair color and individual hair growth variance can impact drug metabolite concentration in hair.

Note: Though often termed "hair follicle tests", the analysis is conducted on the hair strand, not the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Comparing hair and urine tests in Lawrence Creek, OK reveals that hair follicle tests excel in detection effectiveness. While urine tests detect recent use, hair testing offers a longer detection window, providing a more reliable substance history overview.

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.
