Hair Follicle Drug Testing - Central Washita, OK

What it is, How it works

Hair testing is highly regarded as an effective method for identifying drug and alcohol consumption. It offers a prolonged history of substance use by capturing biomarkers within the growing hair fibers. When obtained near the scalp, the hair can reveal a detection period of up to around three months for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.

A 1.5-inch portion comprising roughly 200 strands of hair (comparable to the size of a #2 pencil) taken nearest to the scalp yields 100mg of hair, the preferred amount for analysis and verification. For EtG, extra tests, and/or assessments beyond 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample with a jeweler's scale. Should scalp hair be unavailable, a similar quantity of body hair can be gathered. When mentioning head hair, it implies scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four fundamental phases in laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning centers around integrating a sample into a lab's framework. This process confirms the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any requisite data entry absent from an electronic chain of custody system.

Screening offers an initial rapid evaluation for substances of abuse. While Screening is an economical means to exclude drug utilization in most samples, a positive result necessitates confirmation for legal validity. Any samples indicated as presumptively positive require further confirmation testing.

Should a sample appear presumptively positive at the Screening phase, additional hair is extracted from the original specimen for Extraction. Here, substances are extracted from hair at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), rendering hair drug screening the most intricate methodology to execute.

Confirmation of any positive Screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive undergo cleaning prior to Confirmation as needed. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for as long as 90 days, as opposed to urine tests with a briefer detection span.
• Hard to manipulate: It is notably challenging to deceive a hair drug test, ensuring greater accuracy of results.
• Offers historical insights: It provides an overview of substance use patterns over time, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs usually become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are typically more costly compared to other drug testing techniques.
• Result variations: Elements like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: The term "hair follicle tests" is often used, although the test examines 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
